## Abstract The solvolysis rate constants __k__ for the 6‐__endo__‐substituted 2‐__exo__‐norbornyl toluenesulfonates **7** have been determined. Values of log__k__ correlate well with the respective inductive constants of the substitutents except when the latter are nucleophilic and therefore lead

The large difference between the reaction constants p, for the solvolysis of the 6-exo-and 7-anti-substituted norbornyl tosylates 3 and 1, respectively, is further proof for the hypothesis that 2-norbornyl cations are anisotropic with regard to the transmission of polar effects and that through spac

The effect of substituents at C4, 5, 6 and 7 on solvolysis rates and products of 2-exo-and 2-endo-norbornyl tosylates confirms that differential carbon participation is responsible for varying exo/endo rate and product ratios.
