For the preparation of compounds of formula I wherein Q is a group Qi to Q and R8 is OH, according to Reaction Scheme 1 , Route a), the starting materials used are carboxylic acid derivatives of formula III wherein X is a leaving group, e.g. halogen, for example iodine, bromine or especially chlorine, N-oxyphthalimide or N,O-dimethylhydroxylamino or part of
an activated ester, e.g. (formed from dicyclohexylcarbodiimide
Figure imgf000030_0001
(DCC) and the corresponding carboxylic acid) or 2 s ~~ i '3 3'2 (formed from
N-ethyl-N'-(3-dimethylaminopropyl)-carbodiimide (EDC) and the corresponding carboxylic acid). Those starting materials are reacted in an inert organic solvent, for example a halogenated hydrocarbon, e.g. dichloromethane, a nitrile, e.g. acetonitrile, or an aromatic hydrocarbon, e.g. toluene, and in the presence of a base, for example an alkylamine, e.g. triethylamine, an aromatic amine, e.g. pyridine or 4-dimethylaminopyridine (DMAP), with a dione derivative of formula IV to form isomeric enol ethers of formula Ic. The esterification takes place at temperatures of from 0°C to 110°C.
The isomerisation of the ester derivatives of formula Ic to form the dione derivatives of formula I (R8 = OH) can be carried out, for example, analogously to EP-A-0 369 803 in the presence of a base, for example an alkylamine, e.g. triethylamine, or a carbonate, e.g. potassium carbonate, and a catalytic amount of a cyanide source, for example acetone cyanohydrin or potassium cyanide.
According to Reaction Scheme 1 , Route b), the desired diones of formula I (R8 = OH) can be obtained, for example, analogously to Chem. Lett. 1975, 1045 by esterification of the carboxylic acids of formula Id with the dione derivatives of formula IV in an inert solvent, for example a halogenated hydrocarbon, e.g. dichloromethane, a nitrile, e.g. acetonitrile, or an aromatic hydrocarbon, e.g. toluene, in the presence of a base, for example an alkylamine, e.g. triethylamine, and a coupling agent, for example 2-chloro-1 -methyl-pyridinium iodide. The esterification is carried out, depending upon the solvent used, at temperatures of from 0°C to 1 10°C and yields first, as described under Route a), the isomeric ester of formula Ic, which can be isomerised as described under Route a), for example in the presence of a base and a catalytic amount of a cyanide source, to form the desired dione derivative of formula I (R8 = OH). According to Reaction Scheme 2, the compounds of formula I wherein Q is a group Q5 can be obtained in a manner analogous to that described, for example, in Reaction Scheme 1 or Tetrahedron 36, 2409 (1976), either
a) by esterification of a carboxylic acid derivative of formula III with the hydroxypyrazole derivative of formula IVa in an inert organic solvent and in the presence of a base, or b) by esterification of the carboxylic acid of formula Id with the hydroxypyrazole derivative of formula IVa in an inert solvent in the presence of a base and a coupling agent, and subsequent isomerisation of the intermediately formed ester of formula le, for example with the aid of a base and a catalytic amount of cyanide source.
The preparation of the compounds of formula I wherein Q is the group Q6 can be carried out in accordance with Reaction Scheme 3 advantageously either
via Route a) by reacting the β-diketone derivative of formula V, e.g. analogously to Synthesis 1991 , 301 ; ibid. 1988, 793; or Tetrahedron 32, 3055 (1976), with carbon disulfide in the presence of a base, for example a carbonate, e.g. potassium carbonate, a metal hydride, e.g. sodium hydride, or potassium fluoride on aluminium, and an alkylating reagent of formula VI wherein XT is a leaving group, e.g. halogen, for example iodine, bromine or
especially chlorine, R25OSO2O-, CH3SO2O- or ■ The reaction is
Figure imgf000031_0001
advantageously carried out in a solvent, for example an amide, e.g. N,N-dimethylformamide (DMF), a sulfoxide, e.g. dimethyl sulfoxide (DMSO), or a nitrile, e.g. acetonitrile. The resulting ketene thioacetal of formula VII is cyclised with the aid of hydroxylamine hydrochloride in the presence of a base, for example sodium acetate, in a solvent, for example an alcohol, e.g. ethanol, or an ether, for example tetrahydrofuran, to form a compound of formula If wherein R13 is R25S-. The cyciisation reaction is advantageously carried out at temperatures of from 0°C to 100°C. If desired, the compound of formula If can be oxidised analogously to known standard procedures, e.g. with peracids, for example meta-chloroperbenzoic acid (m-CPBA) or peracetic acid, to form the corresponding sulfone or sulfoxide of formula If (Rι3 = R25SO- or R25SO2-); or can be carried out
via Route b), by converting the β-diketone derivative of formula V analogously to J. Het. Chem. 20, 645 (1983) with an orthoacid amide of formula VIII, for example dimethylformamide dimethyl acetal, into the enamine derivative of formula IX and then cyclising that derivative with the aid of hydroxylamine hydrochloride, in the presence of a base, e.g. sodium acetate, in a solvent, for example an alcohol, e.g. ethanol, to form a compound of formula If.
The preparation of the 4-benzoylisoxazole derivatives of formula I (Q=Q6) wherein R13 is COORie, COR15, cyano, nitro or CONH2 can also be carried out, for example, analogously to WO 96/21357 and references cited therein.
The carboxylic acids of formula Id can be prepared analogously to known procedures, e.g. in accordance with the methods given in Reaction Schemes 4 and 5 below.

ld(R2=CH3;n=1 or 2) The alkenylation of the salicylic acid derivative of formula XX wherein R28 is d-C4alkyl in accordance with Route a) in Reaction Scheme 4 is carried out, for example, analogously to standard etherification methods by means of reaction with an allyl halide of formula XXV wherein Hal is halogen, especially chlorine, bromine or iodine, in an aprotic solvent, for example an amide, e.g. N,N-dimethylformamide (DMF) or 1 -methyl-2-pyrrolidone (NMP), a sulfoxide, e.g. dimethyl sulfoxide (DMSO), a ketone, e.g. acetone, or a nitrile, e.g. acetonitrile, in the presence of a base, for example a carbonate, e.g. potassium or caesium carbonate, or a metal hydride, e.g. sodium hydride. The reaction temperatures are generally in the range of from 0°C to 110°C.
The subsequent Claisen rearrangement of the allyl ether of formula XXI in Reaction Scheme 4 can be carried out, for example, thermally at temperatures of from 100°C to 300°C, optionally in an inert solvent, for example an aromatic hydrocarbon, e.g. xylene. Alternatively the thermal Claisen rearrangement can be carried out, for example, also without a solvent in a microwave oven. Such Claisen rearrangements are described, for example, in C. Ferri, "Reaktionen der organischen Synthese", Georg Thieme Verlag, Stuttgart, 1978, page 461 ff..
In accordance with Reaction Scheme 4, the resulting phenol derivative of formula XXII is then acylated, for example with a thiocarbamoyl halide of formula XXVI, e.g. N,N-dimethyl- thioformyl chloride, in an aprotic solvent, for example an amide, e.g. N,N-dimethylformamide (DMF) or 1-methyl-2-pyrrolidone (NMP), a sulfoxide, e.g. dimethyl sulfoxide (DMSO), a ketone, e.g. acetone, or a nitrile, e.g, acetonitrile, in the presence of a base, for example a carbonate, e.g. potassium or caesium carbonate, or a metal hydride, e.g. sodium hydride. The acylation is advantageously carried out at temperatures of from 0°C to 110°C.
The rearrangement of the thiocarbamate of formula XXIII in Reaction Scheme 4 is effected, for example, thermally in an inert solvent, for example an ether, e.g. diphenyl ether, at temperatures of from 100°C to 300°C and yields the thiolcarbamate of formula XXIV. That compound is then hydrolysed and cyclised using base or acid catalysis to form a compound of formula Id wherein R2 = CH3 and n = 0. This is effected advantageously either with a metal hydroxide, e.g. sodium hydroxide, or with a mineral acid, e.g. hydrochloric acid or sulfuric acid, at temperatures of from 0°C to 110°C. Suitable solvents are, for example, water, ethers, e.g. tetrahydrofuran, halogenated hydrocarbons, e.g. dichloromethane, and aromatic hydrocarbons, e.g. toluene. The resulting benzothiophene derivative of formula Id wherein R2 is methyl and n is 0 can then be oxidised in accordance with various standard methods. Advantageously the oxidation is carried out, for example, with hydrogen peroxide in an acidic solvent, for example an organic acid, e.g. acetic acid, or with an organic peracid, for example meta- chloroperbenzoic acid (m-CPBA), in an inert solvent, for example a halogenated hydrocarbon, e.g. dichloromethane, or an aromatic hydrocarbon, e.g. toluene. The reaction temperatures for the oxidation are generally in the range of from 0°C to 110°C. The degree of oxidation at the sulfur atom (n = 1 or 2) can be controlled by the amount of oxidising agent.
The above reaction sequence via acylation of the phenol derivative of formula XXII to form a thiocarbamate of formula XXIII, rearrangement of the latter compound to form a thiol- carbamate of formula XXIV and hydrolysis and cyclisation to form a compound of formula Id (n = 0) is carried out, for example, analogously to Org. Synth. 51 , 139 (1971 ), and the oxidation to form a compound of formula Id (n = 1 or 2) is carried out, for example, as described in H. O. House, "Modern Synthetic Reactions" W. A. Benjamin, Inc., Menlo Park, California, 1972, pages 334-335 and 353-354.
The electrophilic bromination according to Route b) in Reaction Scheme 4 is carried out, for example, analogously to Chem. Communic. 1972, 214. The bromination of the salicylic acid derivative of formula XX can be effected, for example, in an inert solvent, for example a halogenated hydrocarbon, e.g. dichloromethane, and in the presence of a Lewis acid, for example titanium halide, e.g. titanium tetrachloride, at temperatures of from 0°C to 100°C. The subsequent coupling of the resulting bromosalicylic acid derivative of formula XXb to a trialkyltin-olefin of formula XXVb wherein R29 is d-C alkyl is carried out analogously to Angew. Chem. 98, 504 (1986) in an organic solvent, for example an ether, e.g. tetrahydrofuran, an aromatic hydrocarbon, e.g. toluene, and in the presence a palladium catalyst, for example tetrakis(triphenylphosphine)palladium. The reaction temperature is advantageously from 0°C to 200°C. The coupling product of formula XXII obtained by Route b) can then, for example in a manner analogous to that described under Route a), be acylated, rearranged, hydrolysed and cyclised, and optionally oxidised to form a compound of formula Id.
The aromatic nucleophilic substitution of the ortho-bromobenzoic acid ester of formula XXa wherein R28 is d-C4alkyl in Reaction Scheme 5 can be carried out analogously to known procedures, as described, for example, in J. March, "Advanced Organic Chemistry", 4th Edition, John Wiley & Sons, New York, 1992, pages 641-676. Accordingly, the benzoic acid ester of formula XXa is reacted with an alkenyl sulfide of formula XXVa in an aprotic solvent, for example an amide, e.g. N,N-dimethylformamide (DMF) or 1-methyl-2- pyrrolidone (NMP), a sulfoxide, e.g. dimethyl sulfoxide (DMSO), a ketone, e.g. acetone, or a nitrile, e.g. acetonitrile, in the presence of a base, for example a carbonate, e.g. potassium or caesium carbonate, or a metal hydride, e.g. sodium hydride, at temperatures of from 0°C to 200°C.
The subsequent Claisen rearrangement of the resulting thioallyl ether of formula XXIa in Reaction Scheme 5 can advantageously be carried out in a manner analogous to that described in J. Org. Chem. USSR 13, 2437 (1977) and under Reaction Scheme 4 for the allyl ether of formula XXI, at temperatures of from 100°C to 300°C. The subsequent hydrolysis and cyclisation of the thiophenol of formula XXIIa and the optional oxidation of the resulting dihydrobenzo[b]thiophene derivative of formula Id (n=0) are advantageously likewise carried out as already described under Reaction Scheme 4.
The activated carboxylic acid derivatives of formulae III and I in Reaction Schemes 1 and 2 (Route a)) wherein X is a leaving group, for example halogen, e.g. bromine, iodine or especially chlorine, can be prepared according to known standard procedures as described, for example, by C. Ferri in "Reaktionen der organischen Synthese", Georg Thieme Verlag, Stuttgart, 1978, page 461 ff., such as, for example, in accordance with Reaction Scheme 6 below.

III or I
In accordance with Reaction Scheme 6, the preparation of the compounds of formula III (X = leaving group) and I (X = halogen) is carried out, for example, advantageously by the use of a halogenating agent, for example a thionyl halide, e.g. thionyl chloride or bromide; a phosphorus halide or phosphorus oxyhalide, e.g. phosphorus pentachloride or phosphorus oxychloride, or phosphorus pentabromide or phosphoryl bromide; or an oxalyl halide, e.g. oxalyl chloride, or by the use of a reagent for forming activated esters, for example N,N'- dicyclohexylcarbodiimide (DCC) or N-ethyl-N'-(3-dimethylaminopropyl)-carbodiimide (EDC) of formula X. Where the compound of formula X is a halogenating agent, the group X is, for example, a leaving group, for example halogen, e.g. fluorine, bromine or iodine or especially chlorine, and Wi is, for example, PCI2, SOCI, SOBr or CICOCO.
The operation is optionally carried out in an inert organic solvent, for example in an aliphatic, halogenated aliphatic, aromatic or halogenated aromatic hydrocarbon, for example n-hexane, benzene, toluene, a xylene, dichloromethane, 1 ,2-dichloroethane or chlorobenzene, at reaction temperatures in the range of from -20°C to the reflux temperature of the reaction mixture, preferably at from 40 to 150°C, and in the presence of a catalytic amount of N,N-dimethylformamide. Such reactions are known and various variations thereof in respect of the leaving group X are described in the literature.
The compounds of formulae V, VII and IX (Reaction Scheme 3) are novel. They are important intermediates for the synthesis of the compounds of formula If. The invention therefore relates also to those compounds.
The compounds of formula IV (Reaction Scheme 1 ) wherein Zi = C(R6)R7, Z2 = (W)n6, Z3 = C(R6)R7 and n = 0 are known and can be prepared in a manner analogous to that described, for example, in US-A-5 006 150, WO 97/08164, DE-OS-3 818 958 and DE-OS-3 902 818.
The compounds of formula IV (Reaction Scheme 1 ) wherein Zi = CH, Z2 = O, S or -(CH2)n5-, Z3 = CH and n4 = 2 are known and can be prepared in a manner analogous to that described, for example, in EP-A-0 338 992.
The compounds of formula IV (Reaction Scheme 1 ) wherein Zi = CH2, Z2 = CHNHRg, Z3 = CH2 and n4 = 0 are known and can be prepared in a manner analogous to that described, for example, in EP-A-0 278 907.
The compounds of formula IV (Reaction Scheme 1 ) wherein ZΛ = NR10, Z2 = O, Z3 = C(R6)R7 and n = 0 are known and can be prepared in a manner analogous to that described, for example, in WO 96/26192 and US-A-5 336 662. The compounds of formula IVa (Reaction Scheme 2) wherein Rn and Ri2 are as defined for formula I are known and can be prepared in a manner analogous to that described, for example, in WO 96/26206 and WO 97/08164.
The compounds of formula V in Reaction Scheme 3 can be obtained in accordance with standard procedures, for example from the corresponding esters of formula XXVII
(XXVII),
Figure imgf000039_0001
wherein Ri to R5 and n are as defined for formula I and R28 is d-C4alkyl, for example via Claisen condensation, or from the compounds of formula III by reaction with a ketocarboxylic acid salt of formula XXVIII
COO" M+ CH2 (XXVIII), scoa.
wherein Rι4 is as defined for formula I and M+ is an alkali metal ion (see, for example, WO 96/26192, EP-A-0 496 631 ).
The salicylic acid derivatives of formula XX (Reaction Scheme 4) are either known (some of them being commercially available, for example when R5 is amino (4-aminosalicylic acid)) or can readily be prepared by standard procedures, for example starting from 4-aminosalicylic acid via diazotisation, Sandmeyer reaction and aromatic, nucleophilic substitution (see e.g. J. March, "Advanced Organic Chemistry", 4th Edition, John Wiley & Sons, New York, 1992, pages 641 -676) or Heck reaction of the resulting halide.
The benzoic acid derivatives of formula XXa (Reaction Scheme 5) are either known or can readily be obtained by bromination of the corresponding benzoic acid derivatives (see Reaction Scheme 4, Route b)).
The reagents of formulae VI, VIII, X, XXV, XXVa, XXVb and XXVI used in Reaction Schemes 3 to 6 are either known or can be prepared analogously to disclosed procedures. For the preparation of all other compounds of formula I functionalised in accordance with the definitions of Ri and R2 (2-position of the dihydrobenzo[b]thiophene ring), a large number of known standard procedures are available, for example alkylation, halogenation, acylation, amidation, oximation, oxidation and reduction, the choice of a suitable preparation process being governed by the properties (reactivities) of the substituents in the respective intermediates (see e.g. EP-A-0 796 856).
For the preparation of all other compounds of formula I functionalised in accordance with the definition of R8 wherein Q is a group Qi to Q4, a large number of known standard procedures are available, for example alkylation, acylation and treatment with a sulfur reagent (e.g. P2S5 or Lawesson), the choice of a suitable preparation process being governed by the properties (reactivities) of the substituents in the respective intermediates (see e.g. WO 97/08164 and DE-OS-3 902 818).
All other compounds within the scope of formula I can readily be prepared, taking into account the chemical properties of the dihydrobenzo[b]thiophene or Q moiety in relation to the structure of the dihydrobenzo[b]thiophene or Q rings, in a manner analogous to that described in Preparation Examples P1 to P1 1 or, for example, to that described in the patent specifications indicated.
The end products of formula I can in conventional manner be isolated by concentration or evaporation of the solvent and purified by recrystallisation or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons, by distillation or by means of column chromatography and a suitable eluant. The sequence in which it is advantageous to carry out certain reactions in order to avoid possible secondary reactions will also be familiar to the person skilled in the art. Unless the synthesis is specifically aimed at the isolation of pure isomers, the product may be obtained in the form of a mixture of two or more isomers. The isomers can be separated according to methods known per se.
For the use according to the invention of the compounds of formula I, or of compositions comprising them, there come into consideration all methods of application customary in agriculture, for example pre-emergence application, post-emergence application and seed dressing, and also various methods and techniques such as, for example, the controlled release of active ingredient. For that purpose a solution of the active ingredient is applied to minerai granule carriers or polymerised granules (urea/formaldehyde) and dried. If required, it is also possible to apply a coating (coated granules), which allows the active ingredient to be released in metered amounts over a specific period of time.
The compounds of formula I may be used in unmodified form, that is to say as obtained in the synthesis, but they are preferably formulated in customary manner together with the adjuvants conventionally employed in formulation technology, for example into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. Such formulations are described, for example, on pages 9 to 13 of WO 97/34485. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, wetting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.
The formulations, that is to say the compositions, preparations or mixtures comprising the compound (active ingredient) of formula I or at least one compound of formula I and, usually, one or more solid or liquid formulation adjuvants, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with the formulation adjuvants, for example solvents or solid carriers. Surface-active compounds (surfactants) may also be used in addition in the preparation of the formulations. Examples of solvents and solid carriers are given, for example, on page 6 of WO 97/34485.
Depending on the nature of the compound of formula I to be formulated, suitable surface- active compounds are non-ionic, cationic and/or anionic surfactants and surfactant mixtures having good emulsifying, dispersing and wetting properties. Examples of suitable anionic, non-ionic and cationic surfactants are listed, for example, on pages 7 and 8 of WO 97/34485.
In addition, the surfactants conventionally employed in formulation technology, which are described in, inter alia, "McCutcheon's Detergents and Emulsifiers Annual" MC Publishing Corp., Ridgewood New Jersey, 1981 , Stache, H., "Tensid-Taschenbuch", Carl Hanser Verlag, Munich/Vienna 1981 , and M. and J. Ash, "Encyclopedia of Surfactants", Vol. I-III, Chemical Publishing Co., New York, 1980-81 , are also suitable for the preparation of the compositions according to the invention.
The herbicidal formulations generally contain from 0.1 to 99 % by weight, especially from 0.1 to 95 % by weight, of herbicide, from 1 to 99.9 % by weight, especially from 5 to 99.8 % by weight, of a solid or liquid formulation adjuvant, and from 0 to 25 % by weight, especially from 0.1 to 25 % by weight, of a surfactant. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. The compositions may also comprise further ingredients, such as stabilisers, for example vegetable oils or epoxidised vegetable oils (epoxidised coconut oil, rape oil or soybean oil), anti- foams, for example silicone oil, preservatives, viscosity regulators, binders, tackifiers, and also fertilisers or other active ingredients.
The compounds of formula I can be used successfully either in the form of a mixture of the isomeric forms li to l and Ic (Q is a group Qi to Q4 and R8 is OH) or l6, 17 and le (Q is a group Q5) or in the form of pure isomeric forms to l or Ic, or l6, I7 or le, generally on plants or the locus thereof, at rates of application of from 0.001 to 4 kg/ha, especially from 0.005 to 2 kg/ha. The concentration required to achieve the desired effect can be determined by experiment. It is dependent on the nature of the action, the stage of development of the cultivated plant and of the weed and on the application (place, time, method) and may vary within wide limits as a function of those parameters.
The compounds of formula I are distinguished by herbicidal and growth-inhibiting properties, allowing them to be used in crops of useful plants, especially cereals, cotton, soybeans, sugar beet, sugar cane, plantation crops, rape, maize and rice, and also for non-selective weed control. The term "crops" is to be understood as including also crops that have been made tolerant to herbicides or classes of herbicides as a result of conventional methods of breeding or genetic techniques. The weeds to be controlled may be either monocotyl- edonous or dicotyledonous weeds, such as, for example, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Phaseolus, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.
The following Examples further illustrate but do not limit the invention. Preparation Examples:

Examples of specific formulations for compounds of formula I, such as emulsifiable concentrates, solutions, wettable powders, coated granules, extruder granules, dusts and suspension concentrates, are described on pages 9 to 13 of WO 97/34485.
Biological Examples
Example B1 : Herbicidal action prior to emergence of the plants (pre-emerαence action) Monocotyledonous and dicotyledonous test plants are sown in standard soil in plastics pots. Immediately after sowing, the test compounds, in the form of an aqueous suspension or emulsion prepared from a 25 % wettable powder (Example F3, b), as described, for example, in WO 97/34485, or in the form of an emulsion (prepared from a 25 % emulsifiable concentrate (Example F1 , c), as described, for example, in WO 97/34485), are applied by spraying in a concentration corresponding to 2000 g of active ingredient/ha (500 litres water/ha). The test plants are then grown in a greenhouse under optimum conditions. After a test duration of 3 weeks, the test is evaluated in accordance with a scale of nine ratings (1 = total damage, 9 = no action). Ratings of from 1 to 4 (especially from 1 to 3) indicate good to very good herbicidal action.
Test plants: Cyperus, Sinapis, Solanum
The compounds according to the invention exhibit good herbicidal action.
Examples of the good herbicidal activity of the compounds of formula I are given in Table B1. Table B1 : Pre-emerαence action:

In a greenhouse, monocotyledonous and dicotyledonous test plants are grown in standard soil in plastics pots and at the 4- to 6-leaf stage are sprayed with an aqueous suspension or emulsion of the test compounds of formula I, prepared from a 25 % wettable powder (Example F3, b), as described, for example, in WO 97/34485, or in the form of an emulsion (prepared from a 25 % emulsifiable concentrate (Example F1 , c), as described, for example, in WO 97/34485), in a concentration corresponding to 2000 g of active ingredient/ha (500 litres water/ha). The test plants are then grown on in a greenhouse under optimum conditions. After a test duration of about 18 days, the test is evaluated in accordance with a scale of nine ratings (1 = total damage, 9 = no action). Ratings of from 1 to 4 (especially from 1 to 3) indicate good to very good herbicidal action.
Test plants: Setaria, Sinapis, Solanum, Stellaria
In this test too, the compounds of formula I exhibit strong herbicidal action.
Examples of the good herbicidal activity of the compounds of formula I are given in Table B2.
