Synthesis and Herbicidal Activity of N-(1-Arylethenyl)-2-chloroacetamides

Abstract

N-(1-Alkenyl)-2-chloroacetamides, which bear an aryl substituent at the 1-position of the alkenyl moiety, were synthesized and their herbicidal activities were tested. Some of them were active against paddy field weeds. In particular, a new type of chloroacetamide herbicide, 2-chloro-N-methyl-N-(2-methyl-1-phenylpropen-1-yl)acetamide, having no 2, 6-dialkyl substituted phenyl moiety, which has been considered essential for activity, was found to be active against barnyardgrass.
