SUBSTITUTED CINNAMIC OXIME AND HYDROXAMIDE DERIVATIVES

摘要

Substituted cinnamic oxime derivatives (I) and hydroxamide derivatives (II) (formulae I and II) where R<1> = halogen, NO2, CN, CF3; R<2> = H, halogen; R<3> = H, halogen, C1-C6 alkyl halide, C3-C6 alkenyl, C3-C6 alkinyl, hydroxy-C1-C4 alkyl; R<4> = H, halogen, -S-, -O-CO-, -O-SO2 or a chemical bond; Y' = -O- or -S-; R<5> = possibly substituted C1-C6 alkyl or C1-C6 alkyl halide, C3-C6 alkenyl, C3-C6 alkinyl, possibly substituted phenyl or phenyl C1-C6 alkyl; or, if Y is -O-, -S- or a chemical bond, (C1-C6 alkyl) carbonyl or (C1-C6 alkoxy) carbonyl; or, if Y is a chemical bond, hydrogen or halogen; R<5'> = R<5>, H or (C1-C6 alkyl halide) carbonyl; R<6> = H, C1-C6 alkyl, C1-C6 alkyl halide, C3-C6 cycloalkyl, C3-C6 alkenyl, C3-C6 alkinyl, hydroxy C1-C6 alkyl, C1-C6 alkoxy C1-C6 alkyl, C1-C6 alkylthio C1-C6 alkyl, cyano C1-C6 alkyl, (C1-C6 alkoxy) carbonyl C1-C6 alkyl, (C1-C6 alkyl) carbonyl C1-C6 alkyl, (C1-C6 alkyl) carbonyloxy C1-C6 alkyl or possibly substituted phenyl C1-C6 alkyl or, if Y is oxygen or sulphur, R<5> + R<6> together = substituted C1-C3 alkylene; Cyc = N-(3,4,5,6 tetrahydrophthalimido) or (a), X<1>, X<2> = oxygen or sulphur; R<7> = H, C1-C6 alkyl, C1-C6 alkyl halide, NH2; R<8>, R<9> = H, halogen, C1-C6 alkyl, C1-C6 alkyl halide or possibly substituted phenyl; and salts of I and II. Use: herbicides; desiccation/defoliation of plants.
