Modification of commercially available monophosphine ligands with either aryl bromides or chlorides by rhodium(I)‐catalyzed, tertiary phosphine directed C−H activation is described. A series of ligand libraries containing mono‐ and diaryl‐substituted groups, having different steric and electronic properties, were obtained in high yields. Based on the outstanding properties of their parent scaffolds
描述了通过铑(I)催化的叔膦定向的CH活化来用芳基溴化物或氯化物修饰市售单膦配体。以高收率获得了一系列含有单和二芳基取代基的配体库,这些基团具有不同的空间和电子性质。基于其母体支架的出色性能,已发现修饰的配体在有机反应中具有强大的功能。
