Rates of hydride abstractions from j3-silyl-, j3-germyl-, and B-stannyl-substituted silanes (HSiMeZ(CHz- 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. ~~ ~~ ~~
