effects of substitution on the phenoxy esters have been assessed by means of, the Hammettequation. The results for the methyl esters are related to the steric effect of substituents using the Taft equation. All the pseudo-esters are hydrolysed with rate-determining attack by hydroxide anion at the carbonyl group, followed by rapid ring fission to form the carboxylate anion of the corresponding acid as the
