| 摘要 |
The invention relates to phenyl-propargylether derivatives of the general formula Iincluding the optical isomers thereof and mixtures of such isomers, whereinR1 is hydrogen, alkyl, cycloalkyl or optionally substituted aryl,R2 and R3 are each independently hydrogen or alkyl,R4 is alkyl, alkenyl or alkynyl,R5, R6, R7, and R8 are each independently hydrogen or alkyl,R9 is hydrogen, optionally substituted alkyl, optionally substituted alkenyl or optionally substituted alkynyl,R10 is optionally substituted aryl or optionally substituted heteroaryl, andZ is halogen, optionally substituted aryloxy, optionally substituted alkoxy, optionally substituted alkenyloxy, optionally substituted alkynyloxy, optionally substituted arylthio, optionally substituted alkylthio, optionally substituted alkenylthio; optionally substituted alkynylthio, optionally substituted alkylsulfinyl, optionally substituted alkenylsulfinyl, optionally substituted alkynylsulfinyl, optionally substituted alkylsulfonyl, optionally substituted alkenylsulfonyl or optionally substituted alkynylsulfonyl. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi. |
