4-NITRO-2-TRICHLOROMETHYLBENZENESULFENIC ACID DERIVATIVES, THEIR PREPARATION, AND FUNGICIDES CONTAINING THESE COMPOUNDS

摘要

4-Nitro-2-trichloromethylbenzensulfenic acid derivatives of the formula where R1 is nitroimidazolyl, which is substituted by alkyl, phenyl or benzyl, or R1 is S-alkyl, which is substituted by an S-S-phenyl radical, itself substituted in the phenyl moiety by nitro and trichloromethyl, or which is substituted by -O-CO-R2, where R2 is unsubstituted or substituted alkyl, unsubstituted or phenyl-substituted alkenyl, or unsubstituted or chlorine- or nitro-substituted phenyl, or monoalkylamino or dialkylamino, or unsubstituted or mono-chlorine-substituted or polychlorine-substituted aminophenyl, or R1 is -S-R3, where R3 is unsubstituted or carboxyl-substituted aryl, triazolyl, unsubstituted or alkyl-substituted thiadiazolyl, alkyl-, cyano- or oxo-substituted pyridyl, or unsubstituted or alkyl-, amino-, hydroxy- or oxo-substituted pyrimidinyl. These tives have a fungicidal action that make them usuful as fungicides.
