摘要

Methods of synthesis of acylate phosphabetaines by reactions of triphenylphosphine with methacrylic, cinnamic, and p-methoxycinnamic acids are developed.The phosphabetaine form is proposed to exist in equilibrium with the sigma~5-oxaphospholane form. The features of methylation of the phosphabetaines are discussed.
