Patent number: 6717013
Abstract: The present invention provides an aniline derivative represented by the formula (I)
wherein R1 and R2 are each H, (C1-12)alkyl, (C3-8)cycloalkyl, hydroxy(C1-12)alkyl, hydroxycarbonyl (C1-12)alkyl, (C1-6)-alkoxycarbonyl(C1-6)alkyl, —COR8, wherein R8 is H, halo-(C1-12)alkyl, (C3-8)cycloalkyl or (substituted) phenyl, COOR9, wherein R9 is a halo(C1-6)alkyl group, (substituted) phenyl or (substituted) benzyl; R3, R4, R5, R6 and R7 are each H, halogen, OH, nitro, halo(C1-12)alkylthio, (substituted) amino-(C1-2)alkyl, (substituted) phenyl, (substituted) benzyl, amino, —N(R10)R11 wherein R10 and R11 are each H, alkyl, cycloalkyl, (substituted) phenyl, (substituted) benzyl, —COR8 or COOR9, or (C2-27)perfluoroalkyl, etc., and a process for producing the aniline derivative. According to the process of the present invention, perfluoroalkylaniline derivatives can be obtained by using various anilines as the substrate with a high position selectivity and high yield.

Patent number: 6337341
Abstract: A 1,2,3-thiadiazole derivative represented by general formula (I) or a salt thereof:
wherein R1 is H, (halo) C1-C4 alkyl, 5- or 6-membered heterocycle containing 1 to 3 same or different O, N or S or the like, A is a group of the following formulas:
wherein R2 and R3 are H, halogen, cyano, formyl, alkylthio, alkoxycarbonyl, substituted or unsubstituted phenyl, or the like, or R2 and R3, taken conjointly, may form a 3- to 7-membered ring including a C2-C6 alkylene group which may be intercepted by —O—, —S(O)n— (n is 0-2), —CO— or —NR8— (R8 is H, halogen or the like), B is cyano or an unsubstituted or substituted 5- or 6-membered heterocycle containing 1-3 hetero atoms selected from O, N and S, and m is 0-4; salts thereof; an agrohorticultural disease controller containing said derivative or salt; and method for using said disease controller.
