Abstract

Abstract By reaction of triorganylphosphines with unsaturated dicarboxylic acids adducts of betaine structure were synthesized whose stability depended on the character of substituents at phosphorus and on the structure of acid. The betaine obtained from phosphines and maleic and fumaric acids redily underwent decarboxylation into the corresponding monoacyl phosphonium derivatives. The structure of the latter was ...
