The solvolysisrates and products of the 6endo-R-substituted 2endo-norbornyl toluenesulfonates 6a–6i have been determined. The rates of 6a–6g correlate with the inductive constants σ the 6endo-substituents and are not related to the size of the latter. It is therefore concluded that polar rather than steric effects control the exo/endo-rate ratios of norbornyl sulfonates. Products are derived mainly
