title: Reactions of a methylzirconocene cation with phosphinoalkynes: an alternative pathway for generating Cp2Zr(II) systems.
abstract: A methylzirconocene cation (with a [B(C(6)F(5))(4)](-) counterion) transfers a methyl cation equivalent to diphenylphosphino-alkynes to generate (η(2)-alkyne)ZrCp(2) complexes bearing the [RC≡CPPh(2)Me](+) ligand. Two examples of the PMe(3) ligand stabilized [(Me(3)P)Cp(2)Zr(η(2)-RC≡CPPh(2)Me)(+)][B(C(6)F(5))(4)(-)] salts were characterized by X-ray diffraction.
