Abstract

The lithiocarbyne [W(≡CLi)(CO)₂(Tp*)] (Tp*=hydrotris(3,5-dimethylpyrazol-1-yl)borate) reacts with [PtCl₂(L₂)] (L₂=1,5-cyclo-octadiene, norbornadiene) to furnish ditungsten ethanediylidyne complexes, [W₂{μ-C₂Pt(L₂)}(CO)₄(Tp*)₂], wherein a trigonal platinum(0) center unsymmetrically ligates one W≡C bond in the solid state but rapidly shimmies between the two W≡C bonds in solution. The η⁴-dienes are displaced by monodentate CO or isocyanide ligands to provide derivatives where both W≡C bonds coordinate to a single Pt⁰ center, attended by significant distortion of the WCCW spine.
