Highly diversificated indolylphosphine ligands can be easily accessed by a simple one-pot assembly from commercially available indoles, acid chlorides, and chlorophosphines. The application of this ligand array in palladium-catalyzed Suzuki-Miyaura coupling reaction of aryl chlorides with arylboronic acids allows catalyst loading down to 0.01 mol% of Pd.
