N-Phenylurea as an inexpensive and efficient ligand for Pd-catalyzed Heck and room-temperature Suzuki reactions

N-Phenylurea was found to constitute a highly efficient, yet low-priced, phosphine-free ligand for the Pd-catalyzed Heck and room-temperature Suzuki reactions of aryl bromides and iodides with very high turnover numbers (ca. 103-104).
