Article abstract of DOI:10.1246/cl.1992.489

Gas phase basicities of α-trimethylsilylstyrenes have been determined by measuring proton transfer equilibrium constants.Basicity of α-trimethylsilylstyrene was found to be comparable to that of α-alkylstyrene, suggesting that α-trimethylsilyl group as well as α-alkyl group stabilizes a carbenium ion.
