DETAILS OF THE INVENTION

Compounds of Formula I can be prepared by reaction of the corresponding hydroxy compound (1) with the appropriate sulfonyl halide (2) and a base such as triethylamine or pyridine in a solvent such as dichloromethane or tetrahydrofuran as shown in Equation 1. In Equations 1-11, R¹, R², R³, R⁴, R⁵, R⁶ and G are as previously defined.

Equation 1

Sulfonyl halides 2 can be prepared by the reaction of an alkyl halide (3) with sodium sulfite followed by reaction with a halogenating agent such as phosphorous oxychloride and/or phosphorous pentachloride as shown in Equation 2. Sulfonyl halides can be also be prepared by other methods known to one skilled in the art (see Hoyle, J., In the Chemistry of Sulphonic Acids, Esters and their Derivatives; Patai, S. and

Rappoport, Z., Eds.; Wiley: New York, (1991), pp 351-399). Equation 2

It is known that Compounds 1 can exist as the carbonyl tautomer depending on the nature of the Q group. The synthesis of hydroxy Compounds 1 wherein Q is Q-1, Q-2, Q-3, Q-4, Q-8, Q-9 or Q-10 is described in the art.

A general review for the synthesis of hydroxypyrazoles can be found in Wiley, et al., The Chemistry of Heterocyclic Compounds, Pyrazolones, Pyrazolidones and Derivatives:, Vol. 20, Wiley, New York, (1964). More specifically, the hydroxy Compounds 1 wherein Q is Q-5 can be prepared from the appropriate β-dicarbonyl compound or a synthetic equivalent such as acetylenic ester or α-oxodithioketene acetal and the appropriate Compound 4 in the presence of base as shown in Equation 3. The synthesis of Compounds 4 is known.

Equation 3

Hydroxy Compounds 1 wherein Q is Q-6 can be prepared from alkoxy

compounds 5 by treatment with iodotrimethylsilane or aqueous acid such as hydrobromic acid in acetic acid as shown in Equation 4.

Equation 4

The compounds of Formula 5 can be prepared by treatment of an alkoxypyrazole 6 with the appropriate reagent (7) and base as shown in Equation 5. The synthesis of 4-alkoxypyrazoles is known to one skilled in the art see, for example, Pluempe, H. and Schegk, E., Arch. Pharm., 300, 704, (1967).

Equation 5

Alternatively, compounds of Formula I wherein Q is Q-5 or Q-7 can be prepared by reaction of a pyrazole sulfonate 8 with a compound of Formula 7 and base as shown in Equation 6. The ratio of products obtained will depend on the nature of the R³ and R⁴ groups. In some instances, only one product will be obtained.

Equation 6

The compounds of Formula 8 can be prepared by the reaction of a

hydroxypyrazole 9 with a sulfonyl halide and base as shown in Equation 7. The synthesis of compounds of Formula 9 is known. Equation 7

Analogously, compounds of Formula I wherein Q is Q-6 can be prepared from pyrazole sulfonates of Formula 10 which in turn can be prepared from hydroxy pyrazoles of Formula 11 as shown in Equation 8.

Equation 8

The hydroxy Compounds 1 wherein Q is Q-11 (which will exist predominantly as the carbonyl tautomer) can be prepared by treatment of the NH heterocycle 12 with the appropriate reagent 7 as shown in Equation 9. Equation 9

The compounds of Formula 12 wherein n=0 can be prepared from the appropriate α , β unsaturated acid (or ester) 13 and hydrazine as shown in Equation 10.

Equation 10

The compounds of Formula 12 wherein n=1 can be prepared by reduction of the corresponding compound of Formula 14 as shown in Equation 11. The synthesis of compounds of Formula 14 is known to one skilled in the art.

Equation 11

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of

protection/deprotection sequences into the synthesis will aid in obtaining the desired products. The use and choice of the protecting group will be apparent to one skilled in chemical synthesis. EXAMPLE 1

Arthropod pests are controlled and protection of agronomic, horticultural and specialty crops, animal and human health is achieved by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of foliar and soil inhabiting arthropods and nematode pests and protection of agronomic and/or nonagronomic crops, comprising applying one or more of the compounds of Formula I, or compositions containing at least one such compound, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. A preferred method of application is by spraying. Alternatively, granular formulations of these compounds can be applied to the plant foliage or the soil. Other methods of application include direct and residual sprays, aerial sprays, seed coats, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds can be

incorporated into baits that are consumed by the arthropods or in devices such as traps and the like.

The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, and synergists and other solvents such as piperonyl butoxide often enhance compound efficacy.

The rate of application required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.001 kg/hectare may be sufficient or as much as 8 kg hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required.

The following TESTS demonstrate the control efficacy of compounds of this invention on specific pests. "Control efficacy" represents in3ibition of arthropod development (including mortality) that causes significantly reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Tables A-E for compound descriptions.

TEST A

Southern Corn Rootworm

Test units, each consisting of an 8 ounce (230 mL) plastic cup containing a one- inch square (2.54 cm²) of a wheatgerm diet, were prepared. Solutions of each of the test compound in 75/25 acetone/distilled water solvent were sprayed into the tray and cup. Spraying was accomplished by passing the tray and cup, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 p.s.i. (207 kPa). After the spray on the cups had dried, five second-instar larvae of the southern corn rootworm (Diabrotica undecimpunctata howardi) were placed into each cup. The cups were then held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. The same units were read again at 6 days later. Of the compounds tested, 80% or greater control was achieved using the following compounds: 1, 2, 3, 4, 13, 14*, 15 and 16.

* - tested at 250 ppm.

TEST B

Aster Leafhopper

Test units were prepared from a series of 12 ounce (350 mL) cups, each containing oat (Avena sativa) seedlings in a 1 inch (2.54 cm) layer of sterilized soil. The test units were sprayed as described in TEST A with individual solutions of the test compounds. After the oats had dried from the spraying, between 10 and 15 adult aster leafhoppers (Mascrosteles fascifrons) were aspirated into each of the cups. The cups were covered with vented lids and held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested, 80% or greater control was achieved using the following compounds: 1, 4, 14*, 15 and 16.

* - tested at 250 ppm.

TEST C

Two-Spotted Spider Mite

One inch squares (2.54 cm) of kidney bean leaves that had been infested on the undersides with 25 to 30 adult mites (Tetranychus urticae) were sprayed with their undersides facing up on a hydraulic sprayer with a solution of the test compounds in 75/25 acetone/distilled water solvent. Spraying was accomplished by passing the leaves, on a conveyor belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.55 pounds of active ingredient per acre (about 0.5 kg/ha) at

30 p.s.i. (207 kPa). The leaf squares were then placed underside-up on square of wet cotton in a petri dish and the perimeter of the leaf square was tamped down onto the cotton with forceps so that the mites cannot escape onto the untreated leaf surface. The test units were held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested, 80% or greater control was achieved using the following compound: 4.

TEST D

Boll Weevil

Five adult bollweevils (Anthonomus grandis grandis) were placed into each of a series of 9 ounce (260 mL) cups. The test units were sprayed as described in TEST A with individual solutions of the test compounds. Each cup was then covered with a vented lid and held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, 80% or greater control was achieved using the following compound: 16.

TEST E

Black Bean Aphid

Individual nasturtium leaves were infested with 10-15 aphids (all stages of Aphis fabae) and sprayed with their undersides facing up as described in TEST A. The leaves were then set in 3/8 inch (0.94 cm) diameter vials containing 4 mL of sugar water solution and covered with a clear plastic 1 ounce (29 mL) portion cup to prevent escape of aphids that drop from the leaves. The test units were held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, 80% or greater control was achieved using the following compounds: 15 and 16.
