Ion-cyclotron resonance studies of alkylsilyl ions. VI. The reactions of 2,2-dimethylpropan-1-ol and 1-methoxy-2,2-dimethylpropane with the trimethylsilyl cation

Abstract

The trimethylsilyl cation forms 1 : 1 adducts with both 2,2- dimethylpropan-1-ol and 1-methoxy-2,2-dimethylpropane, with both adducts eliminating C₅H₁₀ by (at least) two mechanisms. One mechanism involves a 1,2-hydride transfer from the carbon α to oxygen to the oxygen acceptor site; the other a 1,4-transfer from a γ-carbon substituent.
