Description

The present invention relates to new and valuable sulfurous diurethanes having an excellent herbicidal action, herbicides containing these compounds, and processes for controlling the growth of unwanted plants with these compounds.

It is known to use methyl-N-(3-(N'-(3'-methylphenyl)-carbaraoyloxy)-phenyl)-carbaraate, ethy1-N-(Ν'-phenylcarbamoy1oxy)-pheny1-carbamate,.methy1-N-(3-N’-methy1-N *-phenylcarb amoy1oxy)-phenyl-carbamate (German Printed Application DAS 1,567,151) and 3-isopropyl-2,l,3-t>en20thiadiazInone-(4)-2,2-dioxide (German Printed Application DAS 1,542,836) as herbicides.

These effects are better than those achieved by prior art active ingredients. - 4 4 6 a 0 s The new compounds may for instance be prepared by the follow12 3 1) ing methods, the radicals A,B,D,E,R ,R ,R ,R and X and n having the above meanings. Where mention is made in the following of urethanes and chloroformic acid esters, these two terms are also intended to cover thiono-, thio- and dithiourethanes and chloroformic acid thionoesters, chloroformic acid thioesters and chloroformic acid dithioesters. 43905 The interrelationships between the starting compounds will be readily apparent from this reaction scheme. It will also be clear that the one or the other route may be more advantageous, depending on the nature of the substituents A,B,D,E,R1,R2,R^,R2t and X, and on the availability of the reactants. The reaction of F to H is preferred.

Starting from prior art m-nitranilines (A), m-nitropheny1iso(thio)cyanates (B) may be produced (W. Siefken, J. Liebigs Annalen der Chemie, 562, 75 et sea., 1949), which in turn smoothly react with the components R^-BH to give nitro(thio)urethanes (C) (S.Petersen,· Methoden der Organ. Chemie, VIII, 131, Georg Thieme-Verlag, Stuttgart, 4th edition, 1952), which are, however, also accessible direct from m-nitranilines (A) with chloroformic acid esters (R^-B-CA-C1) (German Laid-Open Appli)θ cation DOS 1,643,763), or with carbon disulfide or carbonyl sulfide, base and alkylating agent (Methoden der Organ. Chemie, IX, 831 et seq., Georg Thieme-Verlag, Stuttgart, 4th edition, 1955). Subsequent reduction gives the amino compounds (F; R =H) (S. Schroter, Methoden der Organ. Chemie, XI/1, 360 et seq., Georg Thieme-Verlag, Stuttgart, 4th edition, 1957), which are reacted direct, or after conversion into the product monosubο stituted on the amino nitrogen (P; R =H) (Methoden der Organ. Chemie, Xl/1, 24 et seq., Georg Thieme-Verlag, Stuttgart, 4th edition, 1957), with chloroformic acid esters (R^D-CE-Cl) (German Laid-Open Application DOS 1,643,763) or with carbon disulfide or carbonyl sulfide, base and alkylating agent (Methoden der Organ.

Chemie, IX, 831 et seq., Georg Thieme-Verlag Stuttgart, 4th edition, 1955) to give the desired diurethanes (H). The aminourethanes (F) may also be obtained by reaction of m-phenylenediamines (D) with ehloroformic acid esters. Λ further synthesis route is the reaction of aryl-l,3-diBo(thio)cyanates (£) with only one mole of component R^-BH; this reaction gives the iso(thio)cyanatourethanes (G) (J.A. Parker, J.J. Thomas and C.L. Zeise, J. Org. Chem., 22, 594-596, 1957), which are also obtainable by (thio)phosgenation of aminourethanes (F) (German Laid-Open Application DOS 1,914,270, p. 5, Ex. 8). Subsequent 4 reaction with the component R DH gives the desired end products. 4 It should be noted that the -CABR and -CEDR groupings may be in any order.

The preferred synthesis steps are described in more detail below: a) The 3-nitrophenyliso(thio)cyanates (B) are reacted with or without a catalyst conventionally used for iso(thio)cyanate reactions, e.g., tertiary amines (triethylamine, 1,4-diazabicyclo-(2,2,2)-octane), nitrogenous heterocycles (pyridine, 1,2-dimethylimidazole) or organic tin compounds (dibutyl tin diacetate, dimethyl tin dichloride) if desired in a solvent inert under the reaction conditions, e.g., hydrocarbons (ligroin,gasoline, toluene, pentane, cyclohexane), halohydrocarbons (methylene chloride, chloroform, dichloroethane, chlorobenzene, 0-, m- and p-dichlorobenzene), nitrohydrocarbons (nitrobenzene, nitromethane), nitriles (acetonitrile, butyronitrile, benzonitrile), ethers (diethyl ether, tetrahydrofuran, dioxane), esters - 7 46905 (ethyl acetate, methyl propionate), ketones (acetone, methyl ethyl ketone) and amides (dimethylformamide, formamide) (German Laid-Open Application DOS 1,568,138) at from 0° to 150°C, preferably from 40° to 100°C. b) 3-nitranilines (A) are reacted with chlorcforraic acid esters in a suitable solvent, e.g. water, alcohols (methanol, ethanol, isopropanol), or as under a), with the aid of a conventional acid binder, e.g., alkali metal hydroxides, carbonates, bi carbonates, alkaline earth metal oxides, hydroxides, carbonates, bicarbonates and tertiary organic bases (e.g., triethylamine, pyridine, N,N-dimethylaniline, Ν,Ν-dimethylcyclohexylamine, quinoline, trihutylamine), at from -20° to +150°c, preferably from +20° to 80°C. ' c) Nitrourethanes (C) may be reduced by a prior art process, e.g., catalytic hydrogenation, a metal-acid combination such as iron-acid, or a metal-alcohol combination such as zinc dust-aqueous alcohol or iron-aqueous alcohol. d) For the reaction of m-phenylenediamines (D), conditions comparable to those for b) apply; it may be advantageous to employ an excess of m-phenylenediamine. e) Aminourethanes (F) are reacted with chloroformic acid esters analogously to b); the solution obtained for instance by catalytic hydrogenation of nitrourethanes (C) may also be used direct without further purification.

Methyl-N-(3—(N * — (3’-methylphenyl)-carb amoyloxy)-phenyl)-carbamate and ethyl-N-(N'-phenylcarbamoyloxy)-phenyl-carbamate (German Printed Application DAS 1,567,151) are characterized by their - albeit different - action on broadleaved unwanted plants and are well tolerated by sugarbeets. However, as is known, the selectivity of the former compound is better in this crop than that of the latter. The range of application for 3-isopropy1-2,1,3-benzothiadiazinone-(4)-2,2-dioxide (German Printed Application 1,5^2,836) is completely different. This compound is used to combat various broadleaved weeds in soybeans, groundnuts, cereals, Indian corn and some vegetable species. However, there are gaps in the action. Methyl-N-(3—Ν’— -methyl-N'-phenylcarbamoyloxy)-phenyl-carbamate has a herbicidal action good for its class, but hardly any crop plant selectivity; for this reason, the compound has only been recommended for instance in soybeans for post-directed use (Arndt, F. and G. Boroschewsky: New Selective Herbicides, VIII International Plant Protection Congress, Reports and Information, Section III, Chemical Control, Part I, Moscow, 1975, pp. 42-49). In this method, the young shoots and leaves of the crop plants are not contacted by the spray liquor, which is used to treat the unwanted plants growing beneath them. 469 0 5 Examples demonstrating the herbicidal action of the novel sulfurous diurethanes Numerous test results give proof of the good herbicidal properties of the novel compounds. Their herbicidal potency and their selectivity in crop plants are demonstrated in the following examples.

Greenhouse experiments Plastic flowerpots having a volume of 300 cm3 were filled with a sandy loam and test plants, separated by species, were placed therein. Predominantly, seeds were sown or vegetatively reproducing species were transplanted. The active ingredients were suspended or emulsified in water as vehicle and sprayed (postemergence treatment) by means of finely distributing nozzles on to the leaves of the test plants and the surface of the soil. For the postemergence treatment, the plants were grown in the· pots to a height of from 3 to 10 cm, depending on habit, before being treated. Depending on the temperature requirements of the plants, they were placed in either cooler or warmer sections of the greenhouse. The experiments were run for from 2 to 2Q 4 weeks. During the experimental period, the plants were tended and their reaction to the individual treatments was evaluated. The application rates of the compounds are given in kg/ha of active ingredient. The scale for assessment of the activity was 0 to 100, 0 denoting no damage, and 100 complete destruction of the plants.

Results The figures in the- following tables illustrate the action of the active ingredients on treatment after emergence of the crop and unwanted plants (Tables 2 to 18). It is worthy of note that the herbicidal effectiveness and spectrum of action of the new compounds tend toward those of the diurethanes used for comparison purposes. However, their selectivity in crop plants is not the same. This can be excellently exemplified by the results in soybeans and cereals. These crops tolerate the new compounds to the same extent as 3-isopropyl-2,l,3-benzothiadiazinone-(4)-2,2-dioxide, which is known to be well tolerated in these crops (Tables 5,6). In addition, there are a number of crop plants whose tolerance precisely of the compounds according to the invention is conspicuous, whereas the comparative agents are unsuitable (Tables 2, 4, 5).

Possible application methods are soil incorporation or treatment of the soil surface, but the treatment of emerged plants is preferred. Special applications, such as post-directed or lay-by spraying, are also suitable. The jet is directed here in such a manner that the leaves of the sensitive crop plants are if possible not contacted; the agents thus reach the surface of the soil or the unwanted plants growing there.

In view of the variety of application methods, the agents according to the invention or compositions containing them may be used for removing unwanted plants from a much larger number of crop plants than those given in the tables. Application rates may be 0.1 to 15 kg/ha and more, depending on the objective to be achieved.

Of further interest is the fact that the compounds according to the invention may be mixed with mineral salt solutions used to overcome nutritional or trace element deficiencies. / ! 6 9 0 5 To ensure the herbicidal action sets in, spreader-stickers and non-phytotoxic oils may be added.

Application may be effected for instance in the form of directly sprayable solutions, powders, suspensions, disper5 sions, emulsions, oxi dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used; in any case they should ensure a fine distribution of the active ingre10 dient.

Por the preparation; of solutions, emulsions, pastes' and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, etc. and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as benzene, toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes and their derivatives such as methanol, ethanol, propanol, butanol, chloroform, carbon tetrachloride, cyclohexanol, cyclohexanone, chlorobenzene, isophorone, etc., ’20 and strongly polar solvents such as dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, water, etc. are suitable.

Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions or wettable powders by adding water. To prepare emulsions, pastes and oil dispersions the ingredients as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, 469 05 adhere ;s or =. ulsifiers. Concentrates which are suitable for dilution with water may be prepared from active ingredient, wetting agent, adherent, emulsifying or dispersing agent and possibly solvent or oil.

Examples of surfactants are: alkali metal, alkaline earth metal and ammonium salts of ligninsulfonic acid, naphthalenesulfonic acids, phenolsulfonic acids, alkylaryl sulfonates, alkyl sulfates, and alkyl sufonates, alkali metal and alkaline earth metal salts of dibutylnaphthalenesulfonic acid, lauryl ether sulfate, fatty alcohol sulfates, alkali metal and alkaline earth metal salts of fatty acids, salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of sulfated fatty alcohol glycol ether, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylated isooctylphenol, ethoxylated octylphenol and ethoxylated_nonylphenol, alkylphenol polygiycoi ethers, tributylphenol polygiycoi ethers, alkylaryl polyester alcohols, isotridecyl alcohols, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polygiycoi ether acetal, sorbitol esters, lignin, sulfite waste liquors and methyl cellulose.

Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier. 469 0 5 Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acid, silica gels, silicates, talc, kaolin, Attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain flours, bark meal, wood meal, and nutshell meal, cellulosic oowders, etc.

The formulations contain from 0.1 to 95, and preferably 0.5 to 90, ί by weight of active ingredient.
