Halogenation of Et3N, (i-Pr)2EtN, and N-ethylmorpholine or of enamines with dichlorotriphenylphosphorane gives in up to 75% yield the corresponding [2-(dialkylamino)vinyl]triphenylphosphonium chlorides, which can be readily converted into the corresponding stable crystalline tetraphenylborates (Schemes 2 and 3).
Et 3 N,(i-Pr)2 EtN和N-乙基吗啉或烯胺用二氯三苯基磷烷卤化可产生高达75%的产率,相应的[2-(二烷基氨基)乙烯基]三苯基phosph氯化物可以很容易地转化为相应的稳定的结晶四苯基硼酸酯(方案2和3)。
