Phosphine-induced reductive elimination from cis-arylmethylnickel(II) complexes having a 1,2-bis(dimethylphosphino)ethane ligand

Article abstract of DOI:10.1021/om50004a042

A series of cis-arylmethyl(1,2-bis(dimethylphosphino)ethane)nickel(II) complexes, cis-Ni(C₆H₄X)-(Me)(dmpe) (X = p-OMe, p-Me, H, p-F, o-Me), has been prepared by the ligand exchange reaction of trans-Ni-(C₆H₄X)(Me)(PEt₃)₂ with a stoichiometric amount of dmpe at low temperature. Addition of phosphorus ligands such as PEt₃, P(aryl)₃, dmpe, P(OEt)₃, and PCy₃ to the complexes induces facile reductive elimination of MeC₆H₄X.
