Double Insertion of Coordinated Phosphanylalkyne Ligands into a Pt-C(6)F(5) Bond.
Enhanced reactivity is shown by uncoordinated C identical withC bonds in the proximity of a metal in phosphanylacetylene complexes. cis-[Pt(C(6)F(5))(2)(thf)(2)] reacts with [M(C(6)F(5))(2)(PPh(2)C identical withCPh)(2)] (M=Pt, Pd) to form binuclear complexes containing the novel 2,3-bis(diphenylphosphanyl)-1,3-butadien-1-yl bridging ligand. Substitution of the solvent ligands with, for example, PPh(2)H (see picture) provides species that could be characterized by X-ray crystallography.
