This page looks in detail at the mechanism for the formation of esters from carboxylic acids and alcohols in the presence of concentrated sulphuric acid acting as the catalyst. It uses the formation of ethyl ethanoate from ethanoic acid and ethanol as a typical example.

Amide preparation : heat with the amine, methyl or ethyl esters are the most reactive ... Hydrolysis of Esters ... Both are based on the formation of a tetrahedral intermediate which then dissociates.

Acetyl chloride will react with an alcohol (with a base catalyst) to give an acetate ester and we get the same product if we use acetic anhydride. ... The first step of the reaction is the addition of the nucleophilic alcohol to the electrophilic carbonyl group. The base is ... A common base for this reaction is pyridine.

The very significant competition between esterification and demethylation of methyl sterol intermediates of skin suggests that sterol intermediates accumulate in rat skin because of the rapid formation of esters that may not be further metabolized.

The formation of FAEE is catalyzed by acyl-coenzyme A:ethanol O-acyltransferase (AEAT) and by FAEE synthase, which utilize acyl-CoA and free fatty acids, respectively, as substrates. ...

A possible mechanism involving the activation of amino acid inside the cell by formation of aminoacyl adenylate during the protein biosynthesis and further reaction with ethanol intracellular to synthesize the esters is suggested to explain the formation of ethyl esters of amino acid by yeast.

While there are numerous applications of solid-supported reagents and scavengers only a few examples for the formation of esters have been described.3 Carboxylates, generated with solid-supported organic bases, were alkylated with alkyl halides.4 Solid-supported organic bases were also used as scavenger resins in...
