The activity of [Pd(C6H4CH2NH2-kappa(2)-C-N)PPh3MOBPPY]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(C6H4CH2NH2-kappa(2)-C-N)PPh3MOBPPY]OTf complex in N, N-dimethylformamide at 120 degrees C. In comparison to conventional heating conditions, the reactions under microwave irradiation gave higher yields in shorter reaction times.
