Abstract

Treatment of the hydrido hydrosilylene complex Cp∗(CO)2(H)Wi=Si(H)Tsi (1; Tsi = C(SiMe3)3) with 1 equiv of MeIiPr (MeIiPr = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene) caused deprotonation to afford the anionic silylene complex [Cp∗(CO)2Wi=Si(H)Tsi][HMeIiPr] (2). The hydrogen on the silylene ligand of 2 was then abstracted as a hydride with 2 equiv of B(C6F5)3 to give a mixture of 1 and tungsten-silylyne complex Cp∗(CO)2W≡SiTsi (4), from which 4 was isolated in pure form. The molecular structure of 4 was determined by X-ray crystal structure analysis.
