Analysis of the structure-reactivity cross correlations shows the existence of isoparametric relationships in the reaction of Y-substituted benzyl bromides with X-substituted anilines in dioxane and 2, 3, and 5 M solutions of dimethyl sulfoxide in dioxane

The kinetics of the reactions of 3- and 4-substituted benzyl bromides with amines having various structures in nitrobenzene at 40 deg C were investigated.The 4-substituted benzyl bromides have higher reactivity compared with that calculated on the basis of the linear correlations according to the Hammett-Taft equation for unsubstituted and 3-substituted benzyl bromides containing electron-withdrawning substituents.The reactivity of benzyl bromides containing electron-donating substituents obeys a linear correlation with the ?+ constants.The effects of structural changes in the substrate and the nucleophile on the character of the transition states of the investigated reactions is discussed.
