Substitution mechanisms base-catalysed hydrolysis

Hydrolysis of an ester can be achieved by either base- or acid-catalysed reactions, and the nucleophilic substitution mechanisms follow processes that should... [Pg.256]

Analysis of the structure-reactivity cross-correlations shows the existence of isoparametric relationships in the reactions of Y-substituted benzyl bromides with X-substituted anilines in dioxane and in its mixtures with DMSO at 40 The kinetics of hydrolysis of 1-arylethyl ethers of salicyclic acid, catalysed intramolecularly by 0-CO2H, have been studied. Analysis of substituent effects in both arylethyl and leaving groups provides the most detailed available mechanistic insight into a reaction involving efficient intramolecular proton-transfer catalysis. The mechanism is very different from classical general acid-base catalysis. ... [Pg.367]
