ISOTHIAZOLE-5-CARBOXYLIC ESTERS AS MICROBICIDES

摘要

Novel isothiazolecarboxylic esters of formula (I) wherein R<1> represents a hydrogen atom, methyl or ethyl, R<2> represents a hydrogen atom or C1-4 alkyl, R<3> represents a hydrogen atom, chloro, methoxy or nitro, and R<4> represents a hydrogen atom or chloro, provided that where R<1>, R<3> and R<4> each represent a hydrogen atom and R<2> represents methyl, then the group CO2R<2> is bound to the 3-position of the phenyl group. A process for the preparation of the new compounds and their use as microbicides.
