Abstract
Aminal and isocyanate intermediates of the formulas ##STR1## for fungicidal N,N'-diacylaminals of the formula ##STR2## in which R.sup.1 is optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl or cycloalkenyl, R.sup.2 and R.sup.3 are hydrogen or various organic radicals, and X is oxygen or sulphur.
Claims8
An N-(2-cyano-2-oximino-acetyl)-aminal of the formula ##STR75## in which R.sup.1 stands for alkyl optionally substituted by a heterocyclic ring selected from the group consisting of the formula ##STR76## which is optionally monosubstituted, disubstituted or trisubstituted by identical or different alkyl having 1 or 2 carbon atoms,
- R.sup.2 stands for hydrogen or for alkyl optionally substituted by cyano, alkoxy, alkylthio, --COOR.sup.I, acylamino, optionally substituted aryl or optionally substituted cycloalkyl, or R.sup.2 furthermore stands for in each case optionally substituted alkenyl or alkinyl, for in each case optionally substituted cycloalkyl or cycloalkenyl or for optionally substituted aryl,
- R.sup.I stands for hydrogen or alkyl optionally substituted by halogen, or in each case optionally substituted aryl, cycloalkyl or cycloalkenyl, and
- HY stands for the equivalent of an inorganic or organic acid.
An isocyanate of the formula ##STR77## in which R.sup.1 stands for alkyl optionally substituted by a heterocyclic ring selected from the group consisting of the formula ##STR78## which is optionally monosubstituted, disubstituted or trisubstituted by identical or different alkyl having 1 or 2 carbon atoms,
- R.sup.2 stands for hydrogen or for alkyl optionally substituted by cyano, alkoxy, alkylthio, --COOR.sup.I, acylamino, optionally substituted aryl or optionally substituted cycloalkyl, or R.sup.2 furthermore stands for in each case optionally substituted alkenyl or alkinyl, for in each case optionally substituted cycloalkyl or cycloalkenyl or for optionally substituted aryl,
- R.sup.I stands for hydrogen or alkyl optionally substituted by halogen, or in each case optionally substituted aryl, cycloalkyl or cycloalkenyl, and
- HY stands for the equivalent of an inorganic or organic acid.
