SPECIFICATION

THIAZOLYLCINNAMONITRILES AND PEST CONTROLLING AGENTS

Field of Invention:

The present invention relates to novel thiazolylcinnamonitriles and pest controlling agents containing the said compounds as active ingredients.

Background Art:

A large number of pest controlling agents, such as insecticides and acaricides, have been used so far. However, many of them are hardly satisfactory as controlling agents because of insufficient efficacy, restrictions on their use due to drug resistance problems, phytotoxicity or pollution on plants, or strong toxicity on humans, domestic animals and fish. Therefore, there bas been a desire for the development of agents applicable safely and having less of the drawbacks mentioned above.

As for cinnamonitrile derivatives similar to the compounds of the present invention, for example, 3-hydroxy-2-(4-phenyl-2-thiazolyl)-cinnamonitriles are disclosed in Japanese Patent Laid- open No. Sho 53-92769, Japanese Patent Laid-open No. Sho 55-154963 and EP 189960, and their alkali metal and ammonium salts in Japanese Patent Laid-open No. Sho 55-154962. However, none of them has been put to practical use as insecticides because of insufficient efficacy and other problems.

Further, WO 95/29591 and Japanese Patent Laid-open No. Hei 10-158254 have disclosed cinnamonitrile derivatives, similar to the compounds of the present invention, that are useful as anti- fouling agents for aquatic adhesive organisms. There are, however, no descriptions on their insecticidal activities.

Compositions containing the compounds of the present invention obtained in such ways as those mentioned above are useful, for example, as agricultural and horticultural insecticides, acaricides, sanitary insect pest controlling agents and anti- fouling agents for aqueous adhesive organisms. It is particularly preferable to apply compositions containing the compounds of the present invention as agricultural and horticultural insecticides and acaricides.

The compounds of the present invention can be used in the pure form without adding other ingredients, when they are actually applied as agricultural and horticultural insecticides or acaricides. When applied as agrochemicals, they may be used in forms that general agrochemicals can take, such as wettable powders, granules, dusts, emulsifiable concentrates, water soluble powders, flowable concentrates and flowables.

In order to make solid formulations, vegetable powders such as soybean flour and wheat flour; fine mineral powders such as diatomaceous earth, apatite, gypsum, talc, bentonite, pyrophylite and clay; and organic and inorganic compounds such as sodium benzoate, urea and Glauber’s salt can be used as additives and carriers. When the purpose is to prepare liquid formulations, as additives and carriers, petroleum fractions such as kerosene, xylene and solvent naphtha, cyclohexane, cyclohexanone, DMF,

DMSO, alcohol, acetone, trichloroethylene, methyl isobutyl ketone, mineral oils, vegetable oils, water and the like can be used as solvents.

It is possible to further add surfactant, if required, to make these formulations homogeneous and stable forms. There are no particular restrictions on surfactant used.

Their examples include nonionic surfactant such as polyoxyethylene-added alkylphenyl ethers, polyoxyethylene-added alkyl ethers, polyoxyethylene-added higher fatty acid esters, polyoxyethylene-added sorbitan higher fatty acid esters and polyoxyethylene- added tristylylphenyl ethers; polyoxyethylene-added alkylphenyl ether sulfates, alkylbenzenesulfonates, higher alcohol sulfates, alkylnaphthalene sulfonates, polycarboxylic acid salts, lignin sulfonates, condensation products of alkylnaphthalene sulfonates with formaldehyde, and copolymers of isobutylene and maleic anhydride.

An amount of the active ingredient (a compound of the present invention) in a formulation is preferably 0.01 to 90% by weight, more preferably about 0.05 to 85% by weight. The obtained wettable powders, emulsifiable concentrates, flowable concentrates and flowables are diluted with water to specified concentrations to use as suspensions or emulsions. The dusts and granules are used as they are to directly spray on plants or soil.

Many pests such as diamond-back, planthoppers, leafhoppers and aphids, and phytophagous mites have developed resistance against organophosphorus pesticides, carbamate insecticides and acaricides. Therefore, the chemicals have had the problem of lack of efficacy. There has been a desire for chemicals effective on pests and mites of resistant strains. The compounds of the present invention are chemicals having excellent insecticidal and acaricidal effects on pests resistant to organophosphorus pesticides, carbamate insecticides or pyrethroid type agents and mites resistant to acaricides, as well as those of sensitive strains.

The compounds of the present invention induce very slight chemical injuries, have low toxicity on fish and warm-blood animals, and are highly safe.

To a solution of 0.8g (4.2 mmol) of 2-trifluoromethylbenzoic acid in 10 ml of THF was added 0.69g (4.2 mmol) of carbonylbisimidazole, followed by stirring at room temperature for an hour. To the mixture was added 1.0g(4.2 mmol) of 2-cyanomethyl-4- (2,6-difluorophenyl)thiazole, and then, 0.17g (4.2 mmol) of sodium hydride (60% in oil) in an ice-bath. After stirring at room temperature for an hour, another equivalent of sodium hydride (0.17g, 4.2 mmol : 60% in oil) was added, followed by stirring at room temperature overnight. The reaction mixture was poured into ice-water, acidified with dilute hydrochloric acid, and then, extracted with ethyl acetate. The organic layer was concentrated under diminished pressure, followed by chromatography on silica-gel column (ethyl acetate/n-hexane = 1/1, as an eluent) to give 1.1g(64%) of the title compound. Melting point : 170-172C.
