DETAILS OF THE INVENTION
An art expert will appreciate that not everyone
991599463 nitrogen containing heterocycles may form A-oxides since nitrogen requires an electron pair available for oxidation of the oxide; one skilled in the art will recognize those nitrogen-containing heterocycles that may form oxides. One skilled in the art will also recognize that tertiary amines may form A-oxides. Synthetic methods for the preparation of heterocycle A-oxides and tertiary amines are well known to those skilled in the art including oxidation of heerocycles and tertiary amines with peroxyacids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of A-oxides have been extensively described and reviewed in the literature, see for example: TL Gilchrist in Comprehensive Organic Synthesis, vol 7, pp 748-750, SV Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol 3, pp 18-20, AJ Boulton and A.

The starting pyrazoles 12 where R<sup>2</sup> CF3, Cl or Br are known compounds. Pyrazole 12 where R<sup>2</sup> is CF 3 may be prepared by literature procedures (J. Fluorine Chem. 1991, 53 (1), 61-70). Pyrazoles 12 where R<sup>2</sup> is Cl or Br may also be prepared by literature procedures (H. Reimlinger and A. Van Overstraeten, Chem. Ber. 1966, 99 (10), 3350-7). A useful alternative method for the preparation of 12 wherein R<sup>2</sup> is Cl or Br is represented in Scheme 14. Metallation of sulfamoylpyrazole 15 with n-butyllithium followed by direct halogenation of the anion with hexachloroethane (for R<sup>2</sup> where Cl) or 1,2dibromotetrachloroethane (for R<sup>2</sup> where Br) produces halogenated derivatives 16 (where R<sup>2</sup> is Cl or Br). Removal of the sulfamoyl group with trifluoroacetic acid (TFA) at room temperature proceeds cleanly and in good yield to produce pyrazoles 12 wherein R<sup>2</sup> is Cl or Br respectively.

Suitable base may be, for example, but not limited to, sodium hydride, potassium t-butoxide, sodium dimsil (CH<sub>3</sub>S (0) CH2-Na<sup>+</sup>), alkali metal carbonates or hydroxides (such as lithium, sodium or potassium), tetralkyl fluorides or hydroxides (such as methyl, ethyl or butyl) ammonium, or 2-tert-butylimino-2-diethylamino1,3-dimethyl-perhydro -1,3,2-diazaphosphonin. Suitable organic solvent may be, for example, but not limited to acetone, acetonitrile, tetrahydrofuran, dichloromethane, dimethyl sulfoxide, or N, N-dimethylformamide. The cyclization reaction is usually conducted within a temperature range of from about 0 to 120 ° C. The effects of solvent, base, temperature and addition time are all interdependent, and the choice of reaction conditions is important to minimize the formation of by-products. A preferred base is tetrabutylammonium fluoride.
Dehydration of the compound of Formula 18 to give the compound of Formula 19, followed by hydrolysis of the carboxylic ester function, yields the compound of Formula 5. Dehydration is accomplished by treatment with a catalytic amount of a suitable acid. Catalytic acid may be, for example but not limited to sulfuric acid. The reaction is generally conducted using an organic solvent. As one skilled in the art will understand, dehydration reactions may be conducted in a wide variety of solvents, eg acetic acid, in a temperature range generally between about 0 and 200 ° C, more preferably between about 0 and 100 ° C. Carboxylic ester of Formula 19 can be converted to carboxylic acid of Formula 5 by a number of methods including nucleophilic cleavage under anhydrous conditions or hydrolytic methods involving the use of either acids or bases (see TW Greene and PGM Wutts, Protective Groups in Organic Synthesis, 2).<sup>The</sup> ed., John Wiley & Sons, Inc., New York, 1991, pp. 224-269 for a review of methods). For the method of Scheme 15, base catalyzed hydrolytic methods are preferred. Suitable bases include alkali metal hydroxides (such as lithium, sodium and potassium). For example, the ester may be dissolved in a mixture of water and an alcohol such as ethanol. Upon treatment with sodium hydroxide or potassium hydroxide, the ester is saponified to provide
ΡΕ1599463 is the sodium or potassium salt of carboxylic acid. Acidification with a strong acid, such as hydrochloric acid or sulfuric acid, yields the carboxylic acid of Formula
5.
Compounds of Formula 17 wherein R<sup>2</sup> is CF<sub>3</sub> may be prepared by the method outlined in Scheme 16. Treatment of a Formula 20 hydrazine compound with a Formula CH ketone<sub>3</sub>COLOR<sup>2</sup> in a solvent such as water, methanol or acetic acid gives the hydrazone of Formula 21.
Scheme 16
<img file="PT1599463E_D0026.tif" />
One skilled in the art will recognize that this reaction may require catalysis by an optional acid and may also require elevated temperatures depending on the molecular substitution pattern of the Formula 21 hydrazone. Reaction of the Formula 21 hydrazone with an alkyl chloro oxalate in a suitable organic solvent such as
For example, but not limited to dichloromethane or tetrahydrofuran in the presence of an acid scavenger such as triethylamine provides the compound of Formula 17.

A preferred method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention may be applied to plant foliage or soil. Compounds of this invention are also effectively distributed by plant uptake by contacting the plant with a composition comprising a compound of this invention applied as a soil remedy of a liquid formulation, a granular soil formulation, a treatment for a nursery in box or a sprinkler of transplants. The compounds are also effective for topical application of a composition comprising a compound of this invention at the infestation site. Other contact methods include applying a compound or composition of the invention by direct and residual spraying, aerial spraying, gels, seed coatings, microencapsulations, systemic absorption, baits, ear tags, bolus, nebulizers, fumigants, aerosols, powders and many others. The compounds of this invention may also be impregnated with materials for making invertebrate control devices (eg insect nests).
A compound of this invention may be incorporated into the composition of a bait that is consumed by an invertebrate pest or used with devices such as traps, bait stations, and the like. Such a bait composition may be in the form of granules comprising (a) an active ingredient, namely a compound of Formula
ΡΕ1599463
1, an N-oxide, or salt thereof, (b) one or more foods, (c) optionally an attractant, and (d) optionally one or more humectants. Of note are granules or bait compositions comprising from about 0.001-5% of the active ingredient; about 40-99% food and / or attractive; and optionally about 0.05-10% humectants; They are effective in controlling soil invertebrate pests at very low application rates, particularly at active ingredient dosages that are lethal by ingestion rather than by direct contact. Of note some foods will work as a source of food and attractive. Foods include carbohydrates, proteins and lipids. Examples of foods are flour, sugar, starches, animal fat, vegetable oil, yeast extracts and milk solids. Examples of attractants are odorants and flavors such as fruit and plant extracts, perfume, or other animal or plant component, pheromones or other agents known to attract an invertebrate pest. Example of humectants, ie moisture retaining agents, are glycols and other polyols, glycerin and sorbitol. Of note is a bait composition (and a method using such a bait composition) used to control invertebrate pests including individually or in combination with ants, termites, and cockroaches. An apparatus for controlling an invertebrate pest may comprise the present bait composition and a box adapted to receive the bait composition, wherein the box has at least one aperture of adequate size to allow the invertebrate pest to pass through the bait opening. so that

76 invertebrate pest can gain access to the bait composition from an off-box location, and wherein the box is further adapted to be placed on or near the site of the known potential activity of the invertebrate pest.
The compounds of this invention may be applied in their pure state, but most often the application will be a formulation comprising one or more compounds with suitable carriers, diluents and surfactants and possibly in combination with a foodstuff depending on the intended 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, spray tubes, adjuvants, other solvents, and synergists such as piperonyl butoxide often enhance the effectiveness of the compound. For non-agronomic uses such sprays may be applied from sprays such as a can, a bottle or other container, either by pump or by releasing pressurized container, eg a pressurized aerosol spray package. Such spray compositions may take various forms, for example, sprays, mists, foams, fumes or fog. Such spray compositions may still further comprise propellants, foaming agents, etc., as the case may be. Of note is a spray composition comprising a compound or composition of the present invention and a propellant. Representative propellants include, but
ΡΕ1599463 are not limited to methane, ethane, propane, iospropane, butane, isobutane, butene, pentane, iospentane, neopentane, pentene, hydrofluorocarbons, chlorofluorocarbons, dimethyl ether, and mixtures of the foregoing. Of note is a spray composition (and a method of using such a spray composition dispensed by a spray pack) used to control an invertebrate pest including individually or in combination mosquitoes, black flies, stable flies, deer flies, flies of horse, wasps, wasp (yellow jacktets), moscardos, ticks, spiders, ants, mosquito, (gnat), and the like.
The application rate required for effective control (ie biologically effective amount) will depend on such factors as the invertebrate species to be controlled, the pest life cycle, life stage, size, location, time of year, crop or host animal, feeding behavior, mating behavior, environmental humidity, temperature, and the like. Under normal circumstances application rates of about 0.01 to 2 kg active ingredient per hectare are sufficient for pest control in agronomic ecosystems, but as little as 0.0001 kg / hectare may be sufficient or as high as 8 kg / hectare may be required. For non-agronomic 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 high as 150 mg / square meter may be required. . a
The skilled artisan can readily determine the biologically effective amount required for the desired level of invertebrate pest control.
The following TESTS demonstrate the effectiveness of controlling compounds of this invention in specific pests.
