  • Trisubstituted 1,3,5-triazine-2,4,6-triones
    Patent number: 4876253
    Abstract: Fungicidally active trisubstituted 1,3,5-triazine-2,4,6-trione of the formula ##STR1## in which Ar represents optionally substituted aryl,R.sup.1 represents an optionally substituted aliphatic or cycloaliphatic radical andR.sup.2 represents an optionally substituted aliphatic radical,with the provisos that (a) when Ar is unsubstituted phenyl R.sup.1 and R.sup.2 are not alkyl or alkenyl, and (b) when Ar is phenyl substituted by 1 or 2 halogen, lower alkyl, nitro, lower alkoxycarbonyloxy or lower monoalkylcarbonyloxy radicals R.sup.1 and R.sup.2 are not identical alkyl radicals.

  • Preparation of 3-sulphenylmaleimides
    Patent number: 4874874
    Abstract: 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.
