Abstract

Abstract Addition of alcohols to bis (chloromethyl) phosphinoyl isocyanate, as well as the reaction of bis (chloromethyl) phosphinoyl chloride with urethanes or their silylated derivatives, gave the corresponding phosphorylated carbamates which undergo cyclization into 1, 3, 4-oxazaphospholines under the action of Et 3 N.
