N-p-propargyloxyphenethyl-thioacetic acid amides

Abstract

The invention relates to N-propargyloxy-phenethyl thioacetic acid amide derivatives of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein Ris hydrogen, alkyl, cycloalkyl or optionally substituted aryl, Rand Rare each independently hydrogen or alkyl, Ris alkyl, alkenyl or alkynyl, R, R, Rand Rare each independently hydrogen or alkyl, Ris hydrogen, optionally substituted alkyl, optionally substituted alkenyl or optionally substituted alkynyl, Ris optionally substituted aryl or optionally substituted heteroaryl, and Z is hydroxy, optionally substituted aryloxy, optionally substituted alkoxy, optionally substituted alkynyloxy, optionally substituted arylthio, optionally substituted alkylthio, optionally substituted alkynylthio, optionally substituted alkylsulfinyl, optionally substituted alkenysulfinyl, optionally substituted alkynylsulfinyl, optionally substituted alkylsulfonyl, optionally substituted alkenylsulfonyl, optionally substituted alkynylsulfonyl or a group —O—CO—R, —O—CO—O—Ror —O—CO—CO—O—Rwherein Ris hydrogen, optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted aryl or optionally substituted heteroaryl. 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
