摘要: A process for the preparation of a 3-sulphenylmaleimide of the formula ##STR1## in which R.sup.1 is alkyl, or optionally substituted cycloalkyl or aralkyl, andR.sup.2 is optionally substituted alkyl, cycloalkyl, aryl or aralkyl,comprising reacting a 3-sulphenylsuccinimide of the formula ##STR2## with an equimolar amount of hydrogen peroxide in the presence of a lower alkanecarboxylic acid. The compounds are fungicidal and those are new where R.sup.2 is not alkyl, or where R.sup.1 is not alkyl while R.sup.2 is optionally substituted phenyl.
