 Abstract
Kinetics for the nucleophiles have been studied under high vacuum and high pressures in various temperatures. Pseudo-first order rate constants, second order rate constants, thermodynamic parameters and Hammett -values are determined. The values of are all negative. The Hammett r-values are negative for the nucleophile (x) over the pressure range studied. The results of kinetic studies for pressure and nucleophilet show that these reactions proceed in typical reaction mechanism and change of mechanism.
