Abstract

The reaction of the base-stabilized silyliumylidene triflate [LSi(DMAP)]OTf (1·OTf; L = PhC(NtBu)₂, DMAP = 4-dimethylaminopyridine) with [Rh(cod)Cl]₂ and W(CO)₅THF afforded [{L(DMAP)Si} ₂{μ-Rh(μ-Cl)₂Rh(cod)}](OTf)₂ (2) and [L(DMAP)Si→W(CO)₅]OTf (3), respectively. Their crystal structures determined by X-ray crystallography show that the silyliumylidene cation acts as a two-electron donor coordinating to the rhodium and tungsten atoms.
