Ortho-substituted phenylacetic acid amides, process of their preparation, fungicidal agent containing them, and phenyl acetonitrile derivative

摘要

In the present invention, there are disclosed ortho-substituted phenylacetic acid amides of the general formula I, in which W represents an alkoxyimino, alkoxymethylene or alkylthiomethylene group containing 1 to 4 carbon atoms in the alkyl moiety. There are described fungicidal agents containing a liquid or solid carrier substance and at least one amide of the general formula I and process for preparing the amide, wherein the corresponding phenyl acetonitrile derivative of the general formula IV is subjected to hydrolysis in the presence of a base or an acid and subsequently it is subjected on the amide nitrogen to mono- or bisalkylation with alkyl halide. Described are also phenyl acetonitrile derivatives of the general formula IV.
