Modification of commercially available monophosphine ligands with either aryl bromides or chlorides by rhodium(I)‐catalyzed, tertiaryphosphine 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

A phosphorus(III)-directed C−H aminocarbonylation of monodentate phosphines has been developed for modularassembly of bidentate hemilabileligands. The use of mono-N-protected amino acid (MPAA) ligands is crucial for the inhibition of catalyst poisoning.
