α-Dialkylaminomethylphosphines and the corresponding arsines have been obtained by the following methods: (1) by direct Mannich reaction, (2) by reaction of secondary phosphines and arsines with bis(dimethylamino)methane, and (3) by reaction of methyleneammonium halides with secondary phosphines and arsines, silylphosphines and silylarsines, and alkali phosphides and alkali arsides, respectively. The
α-二烷基氨基甲基膦和相应的rs是通过以下方法获得的:(1)通过直接曼尼希反应,(2)通过仲膦和a与双(二甲基氨基)甲烷的反应,和(3)通过亚甲基卤化铵与二级膦和a,甲硅烷基膦和甲硅烷基,以及碱金属磷化物和碱金属砷化物。获得的化合物与N,N具有相似的反应活性-缩醛。氨基甲基被转移到H酸试剂中,与卤化物的反应分别生成亚甲基卤化铵和卤代膦或卤代s啶。对甲基碘的反应性受磷或砷原子上的取代基影响。在磷化合物的情况下,乙酰膦是通过与乙酰氯反应而获得的,而砷化合物则通过加入乙酰氯而得到铵盐。
