The hydride transfer from a hydrosilane to the carbenium ion leads to the transient formation of a complex of tricoordinate silicon cation with solvent. Lambert et al. showed that if a stable counterion of very low nucleophilicity is used, the complex of silylenium ion with solvent is a persistent species [12]. Tetrakis(pentafluorophenyl)borate was successfiilly explored for this purpose, and this system was later used by Olah ef al. [1] for the generation of trisilyloxonium ions derived from D4...
