as well as products, are largely determined by the degree of bridging between the cationic center and a dorsal C-atom in the transitionstate and in the resulting ion pairs. Since bridging is a directed bonding interaction, it is subject to the same angle and conformational strains as ordinary covalent bonds. But bridging requires less geometrical change than the formation of normal bonds and of nonclassical
The solvolysis rates and products of 6-exo- and 6-endo-bicyclo[3.2.1.]-octyl toluenesulfonate confirm that differential bridgingstrain is a major factor in determining the reactivity of epimeric bicyclic sulfonates.
