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

aryl phosphines would provide a foundation for the modularsynthesis of electronically and stericallytunable biaryl phosphines. However, this central task is challenging owing to the unfavorable four-membered cyclometalation and high tendency to undergo further interannular arylation. Herein phenolic compounds have been found to be effective ligands to determine single, double, or triple C–H arylation
