摘要：

The beta-silyl tropylium cation 9 has been successfully generated in the presence of the noncoordinating counterion tetrakis(pentafluorophenyl)borate in benzene and toluene. The C-13 and Si-29 NMR spectra of 9 demonstrate that the beta-silicon substituent interacts strongly with the aromatic pi-system of the cation by hyperconjugation. The crystal structure of 9 shows structural effects consistent with this interaction.
