  Process for the preparation of phosphides, characterized in that phosphides of the general formula R14R15PM are prepared by the reaction in liquid ammonia of an alkali metal M with a phosphine of the general formula R13R14R15P, in which general formulae R13 represents a hydrocarbyl group which may or may not be substituted with polar groups and contains a C = C group which is linked to the phosphorus atom via only one aliphatic carbon atom, R14 is an aryl group which may or may not be substituted with polar groups and R15 represents a hydrocarbyl group which may or may not be substituted with polar groups, with the proviso that if R1 contains a C = C group which is linked to the phosphorus atom via only one aliphatic carbon atom, R1 and R1 are similar to one another.

  制备膦化物的工艺，其特征在于通式 R14R15PM 的膦化物是通过碱金属 M 与通式 R13R14R15P 的膦在液氨中反应制备的，其中通式 R13 代表可以被或不可以被极性基团取代的烃基，并含有仅通过一个脂族碳原子与磷原子相连的 C = C 基团、R14 是可以被或不可以被极性基团取代的芳基，R15 代表可以被或不可以被极性基团取代的烃基，但如果 R1 含有仅通过一个脂族碳原子与磷原子相连的 C = C 基团，则 R1 和 R1 彼此相似。
