1,2,4-Triazol derivatives, a process for their preparation, their use as insecticides and plant growth regulants, and insecticides containing these derivatives

摘要

The invention relates to new compounds of the formula I, IMAGE in which R1 is methyl or phenyl, which is optionally substituted by halogen atoms, (C1-C4) -alkyl radicals or (C1-C4) -alkoxy radicals, and R2 is an R3O group. in the R3 alkyl optionally substituted by halogen, (C1-C4) alkoxy or alkoxycarbonyl, alkynyl cycloalkyl optionally substituted by (C1-C4) alkyl, phenyl optionally by halogen and / or F3C group is substituted, or R2 is an R4 -? - group. in which R4 is hydrogen or (C1-C4) alkyl, which is optionally substituted by alkoxycarbonyl, and R5 (C1-C4) alkyl or phenyl, which is optionally substituted by halogen atoms, F3C radicals, (C1-C4) alkyl or (C1-C4) alkoxy or substituted by phenoxy or halophenoxy means, and a process for their preparation by reacting 1,2,4-triazole with a corresponding halide, and their use for pest control and as plant growth regulators. The halide used as the starting material is produced from the associated acid halide.
