Abstract: PROBLEM TO BE SOLVED: To obtain a new compound providing no fear of phytotoxicity to a useful plant body, having efficient activities for controlling plant disease, and useful as an agrochemical, especially a plant disease-controlling agent. SOLUTION: This new compound is the one of formula I (HetA is a group of formula II or the like; Q is H, a halogen or a lower alkyl; HetB is a group of formula III or the like; Y is H or a lower alkyl; HetC is a group of formula IV or the like; X is a lower alkoxy, cyano or the like; n is 0-3; with the proviso that the case in which HetA is a group of formula II or the like, HetB is a group of formula III or the like, and HetC is a group of formula IV is omitted), e.g. (E)-3-(3-methyl-1,2,5-thiadiazol-4-yl)pyridylmethanone O-(2-pyridyl)methyloxime. The compound of formula I is obtained by reacting a compound of formula V [e.g. 3-(3-methyl-1,2,5-thiadiazol-4-yl)pyridinemethanone oxime] with an alkylating agent (e.g. 2-picolyl chloride) in the presence of a base such as potassium carbonate.

Abstract: PROBLEM TO BE SOLVED: To obtain a new tricyclic phenylpyridine derivative which is useful as a component for practically excellent liquid crystals responding at high speeds in wide temperature ranges, has alkyl side chains not having oxygen functional groups, and contains a pyridine ring. SOLUTION: A tricyclic phenylpyridine derivative of formula I (R1 is a 1-12C alkyl; R2 is a 1-12C alkyl or H; ring A and ring B are each 1,4-phenylene, pyridin-2,5-diyl, provided that the ring B is 1,4-phenylene, when the ring A is pyridin-2,5-diyl). For example, 2-(4decylphenyl)-5-(4-octylphenyl)pyridine. The compound of formula I is obtained, for example, by reacting an alkylbromobenzene of formula II with buthyllithium or the like to form the lithio compound, reacting the lithio compound with trimethyl borate, reacting the obtained borate derivative with 2,5-dibromopyridine in the presence of a palladium catalyst, and then reacting the obtained bromophenylpyridine derivative with a Grignard reagent in the presence of a nickel catalyst.

Abstract: PURPOSE: To obtain an organic compound such as biaryls and alkenylarenes useful as functional organic materials such as liquid crystal, pharmaceuticals and agrochemicals in short step and high yield. CONSTITUTION: The objective unsaturated organic compound of formula R -R is produced by reacting an organic halosilane compound of formula R -SiR m X3-m (R is an aryl, an alkenyl or an alkyl; R is same as R or a lower alkyl; X is a halogen; (m) is 0-2) with an organic halide of formula R -Y (R is an aryl, a 1-alkenyl or a 2-alkenyl; Y is a halogen) in a solvent (e.g. THF) in the presence of a group 10 transition metal catalyst (e.g. triphenylphosphine-palladium acetate) and a base (e.g. NaOH) at 0-200 deg.C. The amount of the catalyst is 0.2-5mol% based on the organic halide and that of the base is 3-10mol based on 1mol of the organic halosilane compound.
