The perchlorates of 7-tropylionorbornane (3), 2-tropyliobicyclooctane (4), and 2-tropylioadamantane (5) were found to undergo stereomutation in acetonitrile at 25-85 deg C, as evidenced by following the change in the 13C NMR spectra of their deuter

Optically active (1-methylpropyl)tropylium ion (1) and (2-bicyclooctyl)tropylium ion (2) have been synthesized.The first-order rate constants of racemization via intermolecular prototropy of 1 provide a novel scale for the kinetic Broensted basicit
