Benzylenol ethers and their use as plant-protective agents

摘要

Benzyl enol ether derivatives of the formula I in which A denotes CH2, CHCl, CH-alkyl, CH-O-alkyl, CH-S-alkyl, N-O-alkyl and B denotes OH, alkoxy, alkylthio and alkylamino, U, V and W are identical or different and denote hydrogen, halogen, alkyl and alkoxy, R<1>, R<2> and R<3> are identical or different and denote hydrogen, cyano, halogen, amino, ester, amide, acyl, S(O)nR<4>, PO(OR<4>)2, alkyl, haloalkyl, cycloalkyl, halocycloalkyl, cycloalkyl-alkyl, alkoxy-alkyl, alkylthio-alkyl, arylthio-alkyl, alkenyl, haloalkenyl, cycloalkenyl, halocycloalkenyl, alkynyl, alkoxy, haloalkoxy, alkylthio, benzylthio, alkylcarbonyl, optionally substituted phenylcarbonyl, optionally substituted benzylcarbonyl, alkoxycarbonyl, optionally substituted phenoxycarbonyl, optionally substituted benzyloxycarbonyl, optionally substituted aryl, optionally substituted aryloxy, optionally substituted arylthio, optionally substituted arylalkyl, optionally substituted arylalkenyl, optionally substituted aryloxyalkyl, optionally substituted arylthioalkyl, optionally substituted hetaryl, optionally substituted hetaryloxy, optionally substituted hetarylthio, optionally substituted heteroarylalkyl, optionally substituted hetarylalkenyl, optionally substituted hetaryloxyalkyl, optionally substituted heterocyclyl and optionally substituted heterocyclyloxy, and the radical R<4> denotes hydrogen and C1-C4-alkyl, and R<1> and R<3> together and also R<2> and R<3> together can in each case form a carbocyclic or heterocyclic ring which, in turn, can be benzo-fused and substituted, and fungicides containing these compounds.
