Abstract

Abstract: Triazolylbenzoylketene S,S-acetals reacted with substituted phenylamines to give triazolylbenzoylketene N,S-acetals,and reacted with O-phenylenediamines,ethylenediamine, ethanolamines and 1-ethanol-2-thiol to afford the corresponding cyclic N,S;N,N;N,O and O,S-acetals. Their structures were identified by elementary and spectral analyses.The preliminary results of bioassay show that some of triazolylbenzoylketene N,S-acetals have plant-regulatory and fungicidal activities.

Key words: α-(1,2,4-Triazol-1-yl)-α-benzoylketene acetals, 1H-1,2,4-triazole, Bioassay
