Enthalpies of activation in solvolysis reactions
Abstract
New data for the rate of solvolysis of PhCH2Cl at 0 and 4 °C fit on the same Arrhenius plot as data at higher temperatures contradicting the sharp change in activation parameters reported by Hills and Viana; the solvent isotope effect at 4 °C is normal and changes in the aqueous solvent between 0 and 4 °C produce no marked effect on the reaction rate of either PhCH2Cl or CMe3Cl.
