摘要：

In this study, the Pd(OAc)2-catalyzed hydrophosphination of terminal alkynes was investigated in detail by using various diphosphines, which have a P-P bond, and the detailed mechanistic insights led to the successful development of a novel Pd-catalyzed hydrophosphination of terminal alkynes using Ph2P(O)H as both the phosphorus and hydrogen source. This catalytic transformation was successfully promoted in the presence of catalytic Ph2P(O)-PPh2, and the corresponding alkenylphosphine oxide was obtained in moderate to excellent yields with excellent product selectivity.
