摘要:
Certain derivatives of cyclopropane carboxylic acid and their esters are useful and valuable intermediates for the preparation of broad spectrum pyrethroid type pesticides. The invention provides a novel method for the preparation of the derivatives of cyclopropane carboxylic acid and esters from stable sulfonium ylides.
