The 2-formyl- and 2-acetylbenzoates of fragrance alcohols and their corresponding pseudo-esters (phthalides) are suitable precursors for the controlled release of fragrances by alkaline hydrolysis; the rate of benzoate hydrolysis depends on the structure of the alcohol released.

2-[(ethylamino)carbonyl]benzoates were found to have the highest rate constants for the alkaline ester hydrolysis, followed by unsubstituted 2-(aminocarbonyl)benzoates, or the corresponding isopropyl derivatives. To rationalize the influence of the different structural changes on the hydrolysis kinetics, the experimental data obtained for the 2-[(alkylamino)carbonyl]benzoates were compared with the
