A series of PdII complexes containing various Group V-donors were reduced with diisobutylaluminum hydride and the products screened as potential catalysts for the coupling of representative vinyl- and aryl-trifluoromethanesulfonate substrates to the Reformatsky reagent BrZnCH(CH3)COOtC4H9.The desired coupling product was obtained only with "reduced" dichlorobis(1,1-diphenylphosphino)ferrocene as catalys and 2-naphthyl triflate as the substrate.These results are discussed in terms of the structural features of the reactants and catalyst.

The invention discloses a benzo polyaza and phosphole oxygen ligand and a complex containing same, a preparation method and application. The invention provides a benzo polyaza and phosphole oxygen ligand as shown in formula I and a complex containing same. A complex of the benzo polyaza and phosphole oxygen ligand and a transition metal halide enables direct coupling of carbon-carbon bonds betweenbig steric hindrance alkyl and aryl; the reaction conditions are gentle; the catalyzing efficiency is high; the coupling reaction process of the carbon-carbon bonds between big steric hindrance alkyland aryl can be extremely simplified; the practicability is high; the reaction cost can be obviously decreased, and the reaction period is reduced; the complex is free from other side products without being required in the catalyzing process. The formula refers to the description.
