The 7-sila-7-norbomadienylcation congener, 4, has a bent structure similar to the 7-norbomadienyl cation (Fig. 19). The silicon chemical shift is strongly shielded in the equilibrium C, structure, but it is deshielded in the Qv transition state 5 (while the chemical shifts of transition structures cannot be observed, the calculated values provide useful interpretive information [49]). The relative stability of 4 vs the 7-norbomadienyl cation is 15.1 kcal mof at MP2-FC/6-31G according to Eq. 3.
