Stereoisomeric ion pairs are implicated as intermediates in the solvolysis of cis and trans-8-hydrindanyl chloride 3, whereas 4-(cyclopenten-1-yl)butyl tosylate 5 appears to cyclize by way of an unsymmetrically solvated 8-hydrindanyl cation. This follows from the solvolysis products and rates of these compounds in aqueous solvents.

The intramolecular Schmidt reactions of tertiary alkyl, tertiarybenzylic, tertiary propargylic, and tertiary allylic carbocations with tethered azides are reported. Using product analysis and deuterium labeling studies, the role of cation rearrangement prior to Schmidt reaction is reported.
