  Isolation of chloro-bridged arylpalladium complexes, [Pd2Ar2(μ-Cl)2(PR3)2], in palladium catalyzed C–C cross coupling reaction of triarylbismuth with arylhalides

  摘要：

  The reaction of [Pd2Cl2(mu-Cl)(2)(PR3)(2)] with triarylbismuth in dichloromethane at room temperature afforded chloro-bridged arylpalladium complexes, [Pd2Ar2(mu-Cl)(2)(PR3)(2)] (Ar = Ph or 4-MeC6H4 (tol)) in 85-90% yield as a yellow crystalline powder. These complexes were characterized by elemental analysis and NMR spectroscopy. Molecular structures of [Pd(2)tol(2)(mu-Cl)(2)(PEt3)(2)] and [Pd2Ph2(mu-Cl)(2)(PMePh2)(2)] were established by single crystal X-ray crystallography. These complexes are centrosymmetric dimers with trans configuration. The C-C coupling reaction between triarylbismuth and an arylhalide in the presence of a base is catalyzed by [Pd2Cl2(mu-Cl)(2)(PR3)(2)]. The reactions proceed via an arylpalladium complex formed by transmetallation reaction between [Pd2Cl2(mu-Cl)(2)(PR3)(2)] and Ar3Bi. Probable reaction routes for C-C coupling have been discussed.
