Dichloro[(2-dimethylamino)propyldiphenylphosphine]palladium (PdCl2(alaphos)) and dichloro[1,3-bis(diphenylphosphino)-propane]palladium (PdCl2(dppp)) were found to be much more effective catalysts than PdCl2(PPh3)2 and other palladium complexes for cross-coupling of sterically congested aryl triflates with aryl and alkynyl Grignard reagents.
