General base catalysis of ester hydrolysis

Both nucleophilic and general base mechanisms of catalysis by acetate anions are observed for the hydrolysis of substituted phenyl formates with leaving

Mechanisms of carbonyl participation in phosphate ester hydrolysis

Revisiting the mechanisms of low-temperature base-catalysed ester

Abstract: Ester interchange reactions such as the interesterification of triglycerides and their transes- terification with methanol (methanolysis) to

Carbanion mechanism of ester hydrolysis. II. o-Nitrophenyl .alpha

The second-order rate constant for alkaline hydrolysis of p-nitrophenyl acetate is within reactions of ester types la and lb with both lyate species.

The mechanism of hydrolysis of a cobalt(III)-bound phosphate ester

The intermediate hydroxo(phosphoramido)tetraammine complex is hydrolyzed slowly by base to liberate phosphoramidate anion by the same mechanism. The ester
