Cyclopropane carboxylic ester(s) with halobenzyl alcohol(s) - useful as insecticides and acaricides, in plant protection, storage of food etc. and in hygienic applications

摘要

Cyclopropane carboxylic esters of formula (I) are new:-(R=F, Cl, Br, and when R=F or Br, then m=0-5, n=0-5 but m and n are not both 0. When R=Cl, m=0-4; n=1-5. When m=0 and n=5, R can also be CH3). (I) have low toxicity to warm-blooded animals, excellent residual activity on wood and clay, and are stable on white-washed surfaces. In an example, reaction of pentafluorobenzyl alcohol with 2,2-dimethyl-3-dichlorovinyl-cyclopropane carboxylic acid gave pentafluorobenzyl 2,2-dimethyl-3-dichlorovinyl-cyclopropanecarboxylate.
