diarylvinylphosphine ligands was designed and synthesized. A catalyst system, consisting of the ligands and palladium species, effectively catalyzed the coupling reaction of aryl bromides and chlorides with amines to afford the corresponding products in good to excellent yields. The efficiency is likely derived from an interaction between the palladium center and the cis-aryl moiety on the diarylvinylphosphine
设计并合成了一系列新的二芳基乙烯基膦配体。由配体和钯物质组成的催化剂体系有效地催化了芳基溴化物和氯化物与胺的偶联反应,从而以良好或优异的收率提供了相应的产物。该效率很可能源自钯中心与二芳基乙烯基膦配体上的顺式-芳基部分之间的相互作用,从而在偶联反应过程中稳定了催化中间体。
