Pd(II)‐Catalyzed Synthesis of Unsymmetrical Biaryls from Tetraphenylborate and Aryl Halides Under Microwave Activation

Abstract A rapid and efficient method for synthesis of unsymmetrical biaryls under microwave irradiation conditions is described. The process involves the reactions of sodium tetraphenylborate with aryl halides in the presence of catalytic amount [PdCl2(PPh3)2] with KF/Al2O3 under microwave irradiation to afford the unsymmetrical biaryls in good to excellent isolated yields.
