Rate coefficients have been measured for the alkalinehydrolysis of 3-substituted phenyl 2-acetyl-and 2-benzoyl-benzoates in 70%(v/v) dioxane–water at several temperatures. The enthalpies and entropies of activation have been evaluated. The effects of substitution have been assessed by means of the Hammett equation. Comparison of the reaction constants with those for model systems, as well as the relative
