摘要用一锅法从元素磷或磷酰亚胺制备了一系列挥发性和非挥发性伯烷基膦和仲烷基膦。元素或氯化物首先通过在萘或另一种增溶试剂存在下与钠反应转化为磷化三钠。随后加入两当量的叔丁醇和烷基卤，以相当好的产率得到单烷基膦。伯膦原位转化为二烷基膦是通过与BuLi或钠的甲基化和随后的烷基化来实现的。
Abstract A number of volatile and non-volatile primary and secondary alkyl phosphines have been prepared by one-pot procedures from elemental phosphorus or from phosphorus trichloride. The element or chloride was first converted into trisodium phosphide by reaction with sodium in the presence of naphthalene or another solubilisation reagent. Subsequent addition of two equivalents of t-butyl alcohol and an alkyl halide gave monoalkyl phosphines in fair to good yields. In situ conversion of the primary phosphine into a dialkyl phosphine was achieved by metallation with BuLi or sodium and subsequent alkylation.
