Structure of primary intermediates of the reaction of P(III) chlorides with aliphatic aldehydes was confirmed by their reactions with such aprotic reagents like ethylene oxide, trialkyl phosphites, acetals, and trialkyl orthoformates. Principle difference in the reactions of these nucleophiles with intermediates containing active chlorine atom at P(III) and those not containing was established. The
P(III)氯化物与脂族醛反应的主要中间体的结构已通过其与非质子传递剂(如环氧乙烷,亚磷酸三烷基酯,缩醛和原甲酸三烷基酯)的反应得到证实。确定了这些亲核试剂与在P(III)处含有活性氯原子的中间体和不含有这些中间体的反应的原理差异。前者以及所有其他P(III)氯化物直接与亲核试剂反应,而后者缓慢分解为醛和P(III)氯化物,后者与亲核试剂反应。
