Abstract

The reaction between nonstabilized alkylidenetriphenylphosphoranes and chlorodifluoromethane has been found to be a useful alternative to the Wittig reaction for the synthesis of many difluoromethylene olefins. Both primary and secondary ylidea which do not contain strongly electron-withdrawing substituents within the alkylidene portion of the ylide react with chlorodiiuoromethane to give the corresponding difluoromethylene olefins ...
