Abstract

Kinetics for the reaction of para-substituted benzyl bromides with 3-picoline have been studied with the changes of substituent, pressure and temperature. The activation parameters and the Hammett ρ-values were determined from the values of rate constants. The results of these studies showed that the positive charge developed in the reaction center and bond cleavage was greater than bond formation. The reaction rate and the ability of charge transfer were increased with elevating pressure. The effect of pressure for the charge transfer was more enhanced at low temperatures.
