Abstract
2-[1-(Trimethylsilyl)vinyl] -2-adamantyl cation (2) was prepared by the ionization of 2-[1-(trimethylsilyl)vinyl]-2-adamantanol in FSO 3 H/SO 2 CF at -130 o C and was characterized by 13 C NMR spectroscopy. For comparison, the 2-vinyl-2-adamantyl cation (4) was similarly prepared and characterized. The cationic center of 2 is deshielded by 11.5 ppm over that of 4, indicating no β-silyl stabilization effect (either inductive or hyperconjugative)
