The second order rate constants have been determined for the nucleophilic substitution reaction of benzylsulfonyl chloride with anilines in MeOH-(Me)_2CO mixtures at 25℃ and 35℃. Results were shown that (ⅰ)the rate constant of the reaction is the largest in 100-90% MeOH solvent and increase with the electron donating substituent anilines, (ⅰ) the magnitudes of ρ and β associated with a change of substituent in the nucleophile are large and indicate a relatively advanced bond-formation in the transition state, (ⅲ) the reaction procceds via S_n2 mechanism with product-like transition state from solvent effect and quantum mechanical approach.
