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
