WebThe nonreversible esterification reaction proceeds via a nucleophilic substitution reaction. 1. Acting as a nucleophile, the alkoxide ion is attracted to the carbon atom of the carboxyl group. 2. The oxonium loses a proton. 3. An unshared electron pair from the alkoxide ion moves toward the carbonyl carbon, assisting the hydroxyl group's exit. WebMechanism of the Fischer Esterification Addition of a proton (e.g.: p -TsOH, H 2 SO 4 ) or a Lewis acid leads to a more reactive electrophile. Nucleophilic attack of the alcohol gives a …

WebNucleophilic acyl substitution describes a class of substitution reactions involving nucleophiles and acyl compounds. In this type of reaction, a nucleophile – such as an alcohol, amine, or enolate – displaces the leaving group of an acyl derivative – such as an acid halide, anhydride, or ester.The resulting product is a carbonyl-containing compound … WebFischer Esterification Steglich Esterification Recent Literature Surprisingly, only a 0.05−2 mol % of DMAP can efficiently promote acylation of alcohols with acid anhydrides under auxiliary base- and solvent-free conditions to give the corresponding esters in high yields.
