A process for the preparation of a 3-sulphenylmaleimide of the formula <IMAGE> in which R1 is alkyl, or optionally substituted cycloalkyl or aralkyl, and R2 is optionally substituted alkyl, cycloalkyl, aryl or aralkyl, comprising reacting a 3-sulphenylsuccinimide of the formula <IMAGE> with an equimolar amount of hydrogen peroxide in the presence of a lower alkanecarboxylic acid. The compounds are fungicidal and those are new where R2 is not alkyl, or where R1 is not alkyl while R2 is optionally substituted phenyl. |
