Rates of hydride abstractions from β-silyl-, β-germyl-, and β-stannyl-substituted silanes [HSiMe2(CH2-MMe3), M = Si, Ge, Sn] and related compounds by diarylcarbenium ions have been measured. The intermediate silicenium ions, produced in the rate-determining step, are stabilized by hyperconjugation, but the effects are much smaller than in comparable carbenium ions.
