Summary

Treatment of the sterically hindered silanes TsiSiRR'H (where RR' = H2 or PhMe and Tsi = (Me3Si)3C) with the hydride abstraction agent Ph3CB(C6F5)4 affords cationic species TsiSiRR'+ which are in equilibrium with bridged cationic species. Bridged cations in which Ph or H bridge between 1,3-silicon atoms have been isolated and characterized by X-ray crystallography.
