Abstract

|
|
The reaction of β-picoline with substituted benzoyl chlorides has been studied by means of conductometry under various pressures in acetonitrile. From the values of pseudo-first order and second order rate constants, the activation parameters (△V≠, △β≠, △H≠, △S≠ and △G≠) and the pressure dependence of Hammett ρ value were studied. The activation volume, the activation compressibility coefficient and the activation entropy were all negative. By increasing pressure the rate constant and Hammett ρ value were increased, and the reaction mechanism was proceed in bond formation favored.
