The rate constants for the base-catalyzed Darzens reactionof p-substituted benzaldehydes and phenacyl chloride have been measured at two temperatures in aqueous dioxane.Enthalpies and entropies of activation have been evaluated.The reactivity of the p-substituted benzaldehydes was found to follow the order p-NO2> p-Cl> p-Br> H> p-CH3> p-OCH3.The kinetic data can be correlated with ρ values according to the Hammett equation.
