Kinetic studies of nucleophilic substitution reactions of substituted benzenesulfonyl chlorides with substituted N,N-dimethylanilines were conducted at 35.0℃ in methanol. Results showed that (ⅰ) the magnitude of ρ_X and β_X associated with a change of substitutent in the nucleophile are large and indicate a relatively advanced bond-formation in the transition state, (ⅱ) The large negative cross-interaction constant. ρ_(XY) = -0.53. These values show that aminolysis of benzenesulfonyl chlorides proceeds by S_N2 mechanism with some S_N2 -S_AN border reaction.
