Abstract

A novel class of phosphinic acid derivatives, four-membered cyclic oxaphosphetanes, was synthesized by the reaction of bis(hydroxymethyl)phosphinic acids with a mixture of triphenylphosphine and diisopropyl azodicarboxylate in toluene-dichloromethane at room temperature via an intramolecular Mitsunobu reaction.
