The activity of [Pd(C 6 H 4 CH 2 NH 2 ‐κ 2 ‐C‐N)PPh 3 MOBPPY]OTf complex, A (MOBPPY = 4‐methoxybenzoylmethylenetriphenylphosphoraneylide) was investigated in the homocoupling reaction of a vast range of aryl halides under both conventional and microwave irradiation conditions and their results were compared. The complex was active and showed high efficiency in the formation of new C‐C bonds. The yields were excellent using a catalytic amount of [Pd(C 6 H 4 CH 2 NH 2 ‐κ 2 ‐C‐N)PPh 3 MOBPPY]OTf complex in N , N ‐dimethylformamide at 120 °C. In comparison to conventional heating conditions, the reactions under microwave irradiation gave higher yields in shorter reaction times. Copyright © 2011 John Wiley & Sons, Ltd.
