1,3,3-Trimethylbicyclo[2.2.1]heptan-2-endo-ol (fenchol) reacts with acetonitrile in the presence of sulfuric acid to selectively form an isofenchane derivative - N-acetyl-1,5,5-trimethylbicyclo[2.2.1]heptan-2-exo-amine as a result of nucleophilic addition at the most accessible carbon atom of a nonclassical 1,3,3-trimethylbicyclo[2.2.1]heptyl cation. The H2SO4-catalyzed reaction with acetic acid results in exclusive formation of 1,3,3-trimethylbicyclo[2.2.1]hept-2-exo-yl acetate, implying an SN2 reaction mechanism.

Solvolysis of 2αH-pinan-3α-yl toluene-p-sulphonate has been shown to proceed with concomitant 1,2-hydride shift to give the pinan-2-yl carbocation.Contrary to earlier reports, this species reacts normally to give, in good yield, pinan-2-yl substitution products.In contrast the pinan-3-ylamines react via a similar route, but give much smaller amounts of pinan-2-yl products.The usual reasons for differences between solvolysis and deamination (i.e. the intermediacy of diazonium ions and/or high-energy ions) can be discounted, and possible reasons for the differences in behaviour are discussed.
