Solvolysis of 3-substituted 4-homoadamantyl methanesulphonates. Can the ?-substituent effect distinguish between classical and non-classical ion intermediates?
that 3 (R = H) solvolyses via a classical ion intermediate. The logarithms of the solvolysis rate constants of 3 showed linear correlations with those of 1-R-2-adamantyl tosylates (1) and 1-R-exo-2-norbornyl tosylates (2), indicating that the linear free-energy relationship between the β-substituent effects on the solvolysis rate is not a definite measure to distinguish between classical and non-classical
