Formula (IV) → Formula (I) The aminoacetonitrile derivative of the formula (I) can be produced by reacting aminoacetonitrile derivatives of the formula (IV) with acid halides of the formula (III) in the presence of a base (for example, triethylamine, pyridine, etc.). The aminoacetonitrile derivative of the formula (I) can also be produced by condensation-reacting aminoacetonitriles of the formula (IV) with acids of the formula (II) by use of a condensing agent (for example, dicyclohexylcarbodiimide, 2-chloro-1-methylpyridiniumiodide, etc.). The acids of the formula (II) can be produced by known methods (for example, J. Org. Chem. 763, 1948, Organic Synthesis Coll., Vol. 1, 436, J. Org. Chem. 763, 1948, Organic Synthesis Coll., Vol. 1, 336, Beilsteins Handbuch 9, 573, Beilsteins Handbuch 9, 633, etc.). 2. Formula (VII)→ Formula (IV) The aminoacetonitriles of the formula (IV) can be produced, for example, by the reaction of carbonyl compounds of the formula (VII) with metal cyanides of the formula (VI) (for example, sodium cyanide, potassium cyanide, etc.) with amines of the formula (V). As the CN source, organic cyanides such as trimethylsilylnitrile and acetonecyanohydrin can be used. These reactions are a method known as Strecker reaction (for example, Formation of C-C Bonds Vol. 1, Georg Thieme Publishers 1973, Organic Synthesis Coll. Vol., 3, 88, etc.). The carbonyl compounds of the (VII) can be produced, for example, by the following production method. wherein R 3 , R 4 , R 5 , Ar 1 , Ar 2 , and a have the same meanings as described above, L represents a leaving group such as a halogen atom, a methylsulfonyloxy group or a p-methylbenzenesulfonyloxy group, W' is OH, SH or NHR 9 (where R 9 has the same meaning as described above, Rs are C 1 -C 6 alkyl groups which may be the same or different and represent a C 1 -C 4 alkylene group, or Rs together form a C 1 -C 4 alkylene group. The carbonyl compounds of the formula (VII) can be produced, for example, by reacting a compound of the formula (VIII-1) having a leaving group L with a compound of the formula (IX-1) in the presence of a base. Similarly, the carbonyl compounds of the formula (VII) can also be produced by reacting a compound of the formula (VIII-2) with a compound of the formula (IX-2). Moreover, the carbonyl compounds of the formula (VII) can be produced by deprotection-reacting a compound of the formula (XII) derived by reacting a compound of the formula (X-1) whose carbonyl group is protected in the form of acetal, ketal or the like with a compound of the formula (IX-1), under acidic conditions. Similarly, the compounds of the formula (XII) can be produced by reacting a compound of the the formula (X-2) with a compound of the formula (IX-2). Further, the carbonyl compounds of the formula (VII) can be produced by oxidizing a compound of the formula (XIII) derived by reacting an alcohol compound of the formula (XI-1) with a compound of the formula (IX-1) with using a suitable oxidizing agent (for example, potassium permanganate, etc.). Similarly, the compound of the formula (XIII) can be produced by reacting an alcohol compound of the formula (XI-2) with a compound of the formula (IX-2).

The agricultural and horticultural insecticide of the present invention is generally formulated in appropriate formulation convenient for use according to conventional methods for the production of agricultural chemicals before it can be used. That is, the aminoacetonitrile derivative of the formula (I) may be mixed in an appropriate amount with a suitable inert carrier and, as required, with an adjuvant to conduct dissolution, dispersion, suspension, mixing, dipping, adsorption or absorption and the mixture be formulated into a suspension, an emulsion, a liquid, a wettable powder, a granule, a dust, tablets or the like. The inert carrier which can be used in the present invention may be any of solids or liquids. Materials which can be used as solid carriers include, for example, soybean flour, cereal flour, wood flour, bark flour, sawdust, tobacco stalk flour, walnut shell flour, wheat bran, cellulose fiber, residue after formation of a plant extract, synthetic polymers such as pulverized synthetic resin, clays (for example, kaolin, bentonite, acid clay, etc.), talcs (for example, talc, pyrophillite, etc.), silicas (for example, diatomaceous earth, quartz sand, mica, white carbon (fine hydrated silicon, also referred to as silicic acid hydrate, which contains high-dispersion silicic acid; some products contain mainly calcium silicate), activated carbon, sulfur powder, pumice stone, calcined diatomaceous earth, brick pulverization product, fly ash and sand, inorganic mineral powders such as calcium carbonate, calcium phosphate, chemical fertilizers or composts of ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and ammonium chloride. These may be used singly or as mixtures of two or more of them. The liquid carrier includes one having itself a solvent effect and one free from a solvent effect but can disperse the active ingredient using an adjuvant. Typical examples include the following carriers, which can be used singly or as mixtures of two or more of them, for example, water, alcohols (for example, methanol, ethanol, isopropanol, butanol, ethylene glycol, etc.), ketones (for example, acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, cyclohexanone, etc.), ethers (for example, ethyl ether, dioxane, Cellosolve, dipropyl ether, tetrahydrofuran, etc.), aliphatic hydrocarbons (for example, kerosene, mineral oil, etc.), aromatic hydrocarbons (for example, benzene, toluene, xylene, solvent naphtha, alkylnaphthalen, etc.), halogenated hydrocarbons (for example, dichloroethane, chloroform, carbon tetrachloride, chlorinated benzene, etc.), esters (for example, ethyl acetate, phthalate, diisopropyl phthalate, dibutyl phthalate, dioctyl phthalate, etc.), amides (for example, dimethylformamide, diethylformamide, dimethylacetamide, etc.), nitriles (for example, acetonitrile, etc.), dimethyl sulfoxide, and the like. Other adjuvants include typical adjuvants exemplified below. These adjuvants are used depending on the purpose and they can be used singly or two or more of adjuvants can be used in combination. Alternatively, no adjuvant can be used in some cases. For the purpose of emulsification, dispersion, solubilization and/or wetting of the active ingredient compound, a surfactant is used. Examples of the surfactant include, for example, polyoxyethylene alkyl ether, polyoxyethylene alkylaryl ether, polyoxyethylene higher fatty acid ester, polyoxyethylene resin acid ester, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monooleate, alkyl aryl sulfonate, naphthalenesulfonic acid condensate, ligninsulfonate, higher alcohol sulfate, etc. The adjuvant can be used to stabilize the active ingredient compound and to adhere or bind the active ingredient compound. Examples of such an adjuvant includes casein, gelatin, starch, methyl cellulose, carboxymethylcellulose, gum Arabic, polyvinyl alcohol, wood turpentine oil, rice bran oil, bentonite, lignin sulfite liquor, etc. The adjuvant can be used to improve fluidity of solid products. Examples of such an adjuvant is, for example, wax, stearates, alkyl phosphates, etc. As the deflocculant for suspension products, adjuvants such as naphthalenesulfonic acid condensates, condensed phosphates, etc. can be used. As the defoaming agent, adjuvants such as silicone oil can be used. The amount of the active ingredient compound may be adjusted, if desired. For example, 0.01 to 50% by weight is suitable in the case of dust or granule and 0.01 to 50% by weight is also suitable in the case of emulsions and wettable powder. In order to control various pests, the agricultural and horticultural insecticide of the present invention can be applied in an amount effective to prevent insect damages as it is or suitably diluted with or suspended in water or the like, to crops on which emergence of the pests is expected or to the place where emergence of the pests is undesirable. The amount of the agricultural and horticultural insecticide of the present invention may vary depending on various factors such as purpose, pests to be treated, state of growth of crops, trend of emergence of pests, weather, environmental conditions, formulations, application methods, application sites and application periods. However, it may be selected suitably depending on the purpose within the range of 0.1 g to 10 kg per 10 ares as the active ingredient compound. The agricultural and horticultural insecticide of the present invention can be used in combination with other agricultural and horticultural agents for controlling diseases insect pests in order to further extend diseases and pests, optimal controlling time or reduce doses.
