Substituent effects of leaving group in benzylarenesulfonates solvolysis have been carried out in 10∼50% water-acetone mixtures by electric conductivity method. Results of solvent effects, substituent effects and variable rate difference of water contents, show that SN1 character almost predominates through the substituents, though p-MeO favors more or less SN2 character in low water contents.
