以市售路易斯酸、9-BBN和路易斯碱[Et4N]Cl为催化剂，在苯基硅烷存在下还原氯膦R2PCl。芳基氯膦主要提供二膦（P2R4），而烷基取代前体主要提供仲膦。使用组合催化剂可减少反应时间和温度，为二膦或仲膦的制备提供了快速、可扩展和简便的方案。
The commercially available Lewis acid, 9-BBN and Lewis basic [Et4N]Cl are used as catalysts for the reduction of chlorophosphines R2PCl in the presence of phenylsilane. Aryl-chlorophosphines afford primarily diphosphines (P2R4) while secondary phosphines predominate for alkyl-substituted precursors. Use of the combined catalysts leads to reduced reaction time and temperature, providing a rapid, scalable, and facile protocol for the preparation of diphosphines or secondary phosphines.
