A series of novel 2‐methylthio‐3′/4′‐substituted acetophenone oxime O ‐ethers were synthesized by the reaction of the corresponding acetophenone oximes with halides of pyrethroid alcohols in the presence of sodium hydroxide and phase‐transfer catalysis or with triethyl quaternary ammonium salts of halides of pyrethroid alcohols in the presence of sodium hydroxide. These compounds showed notable insecticidal activity against Homopteran and Lepidopteran pests. 2‐Methylthio‐4′‐fluoroacetophenone oxime O ‐[(2‐methylbiphenyl‐3‐yl)methyl] ether was more effective than the commercial insecticides chlorfenapyr and fenvalerate.
