Correlation of the Rates of Solvolysis of Electron-Rich Benzoyl Chloride Using the Extended Grunwald-Wistein Equation

for many years.However, the mechanismsof most of these reactions remain not well established,especially for electron-rich acyl transfer reactions. In order to obtain further understanding of the electron-rich acyl transfer mechanism, a kinetic study of the solvo-lysis of piperonyloyl chloride (1) (Eq. 1) in a variety of pureand binary solvents at 25.0 ??C was undertaken. Furthermore,the l, m, and h values were determined using the extendedGrunwald-Winstein equations [Eqs. (2) and (3)];
