Abstract

4-Nitro-2-trichloromethylbenzenesulfenic acid derivatives of the formula ##STR1## where R.sup.1 is nitroimidazolyl, which is substituted by alkyl, phenyl or benzyl, or R.sup.1 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--R.sup.2, where R.sup.2 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 R.sup.1 is --S--R.sup.3, where R.sup.3 is unsubstituted or carboxyl-substituted aryl, triazolyl, unsubstituted or alkyl-substituted thiadiazolyl, unsubstituted or alkyl-, cyano- or oxo-substituted pyridyl, or unsubstituted or alkyl-, amino-, hydroxy- or oxo-substituted pyrimidinyl, and fungicides containing these compounds.
