The rate constants (log k) for solvolysis of 2-, 3-, and 4-substituted bicyclooctyl p-nitrobenzenesulfonates 10, 11, and 12, respectively, correlate linearly with the corresponding inductive substituent constants ?qI.The formation of the ion pairs 9 is, therefore, controlled by the I effect of the neighboring substituents.It follows from the corresponding reaction constants ρI of -1.54, -1.12, and -1.22 that inductivity is highest at the positions α to C(1).It is lower and practically equal at the β- and γ-positions.Therefore, charge dispersal is similar to that previously observed in the quinuclidinium ion 7.
