Attack of isocyanide and carbon monoxide on a bridging alkylidyne ligand at a ditungsten centre. Cleavage of the C-N and C-O triple bonds with respective formation of tungsten-imido and -oxo groups and concomitant addition of the carbon atom to the bridging alkylidyne carbon yielding a bridging σ-W 12-W2 alkynyl ligand

Abstract

Isocyanide ligands and carbon monoxide, C≡X, where X = NBu t, NC6H3Me2-2,6, and O, react in hydrocarbon solvents with [(PriO)2W(μ-CSiMe 3)]2 to give compounds of formula (PriO)(X=) W(μ-CSiMe3)(μ-η21-CCSiMe 3)W(OPri)3; the compound where X = 2,6-dimethylphenylimido has been characterized by an X-ray study while that for X = O is formulated as an analogue based on i.r. and n.m.r. data.
