Abstract
The ortho-metallated complex [Pd(μ-Cl){ κ 2( C, C)-[C 6H 4(PPh 2CHC(O)C 6H 4-Ph-4)}] 2 ( 2a) was prepared by refluxing of Pd(OAc) 2 and {(Ph) 3PCHCOC 6H 4-Ph-4} (PhBPPY) of in CH 2Cl 2 followed by addition of an excess of KCl in MeOH Complex ( 2a) reacts with triphenylphosphine to give the mononuclear derivative [Pd(Cl)(PhC 6H 4COCHPPh 2C 6H 4)(PPh 3)] ( 3a) whose crystal structure has been determined by single crystal X-ray diffraction. The Suzuki reactions of aryl bromides and chlorides of varying electron density using complex ( 3a) as an efficient catalyst were performed, giving the cross-coupling products in good to excellent yields.
