Tungsten–platinum μ-carbido and μ-methylidyne complexes

Abstract

Reactions of the lithiocarbyne [W]CLi ([W] = W(CO)₂(Tp*); Tp* = tris(dimethylpyrazolyl)borate) with divalent platinum complexes [PtCl(terpy)]PF₆, [PtCl₂(η-C₄R₄)] (R = Me, Et), and [PtCl₂(phen)] afford access to μ-carbido, μ-methylidyne and carbyne-based metallo-ligand complexes [Pt(C[W])(terpy)]PF₆, [Pt(μ-HC[W])₂] and [Pt(C[W])Cl(phen-C[W]-2)], respectively, the last of which provides a rare example of intermolecular organometallic nucleophilic attack at coordinated phenanthroline.
