Abstract
4-Chlorophenyl cyclopropyl ketone is synthesized by acylation and cyclization with 4-chlorobutyryl chloride and chlorobenzene as starting materials.Intermediate of flucycloxuron,an insecticide,(4-chlorophenyl)(cyclopropyl)methanone O-(4-nitrobenzyl)oxime is obtained in "one-pot" reaction with the 4-chlorophenyl cyclopropyl ketone,hydroxylamine hydrochloride and p-Nitrobenzyl bromide as starting materials,the yield was 70.6%.The structure of the product and intermediates is characterized by 1H NMR and IR.The process can be simplified and the yield of(4-chlorophenyl)(cyclopropyl)methanone O-(4-nitrobenzyl)oxime increased through optimization.
