Abstract
3-(2'-chloro-3',3',3'-trifluoropropenyl)-2,2-dimethylcyclopropane-1-carboxy lic acid esters are prepared by dehydrohalogenation of the corresponding 3-(2',2'-dichloro-3',3',3-trifluoropropyl) compounds by reaction with an alkali metal carbonate in a polar aprotic solvent. The products are intermediates in the preparation of pyrethroid insecticides or are themselves insecticides.
