The Reaction of Benzyl Arenesulfonate with N,N-Dimethylanilines (). Substituent Effects of Leaving Group for Benzyl Arenesulfonate

[摘要] Substituent effect of the leaving groups of the reaction of benzyl arenesulfonate with dimethylanilines in acetone at 35¡É was obtained with the following results. 1. Substituent effect of the leaving groups was not variable when changed from pyridine to N,N-dimethylaniline in nucleophile 2.In acetone, the Hammett ¥ò constant of p-MeO of the leaving group was -0.35. 3. The weaker the nucleophilicity in dimethylaniline, the stronger the movement of electron from N to C, and the cleavage of the C¡¦0 bond in transition state proceeds.
