摘要:
Compounds having the general formula: wherein R is H, alkyl, cycloalkyl or cycloalkylalkyl, optionally substituted alkenyl or optionally substituted alkynyl, optionally substituted benzyl, or a metal ion; R' is an alkenyl, alkynyl, cyanoalkyl, heterocyclyl or allenylmethyl group, any of which groups can bear substituents or R 1 is alkyl substituted by alkoxy, halogen, alkylthio, alkoxycarbonyl, carbamoyl, alkylcarbamoyl or thiocarbamoyl; or R 1 is alkyl substituted by thiocarbamoyl and additionally by either optionally substituted aryl or optionally substituted heterocyclyl; R 2 is H or is a cyanoalkyl, alkenyl, alkynyl or allenylmethyl group, any of which groups can bear substituents; have fungicidal activity.
