The substitution reactions of methyl para-substituted benzenesulfonates with nucleophils such as methanol, pyridine and sodium methoxide in methanol at 30℃ were investigated by conductometry and spectrometry in order to understand the reactivityselectivity relationship. The Hammett plot of kinetic data showed ρ values of 1.29, 1.18, 1.04 for the nucleophilic substitution reaction with methanol, pyridine and methoxide, respectively. Taking ρvalues as a selectivity parameter of the nucleophiles and considering the results with a series of nucleophiles showing the increase of reactivity in that order, there seems to be an inverse relationship between reactivity and selectivity.
