    Yamaguchi Esterification

    Yamaguchi Esterification. The Yamaguchi Esterification allows the mild synthesis of highly functionalized esters. After formation of a mixed anhydride between the Yamaguchi Reagent (2,4,6-trichlorobenzoyl chloride) and the carboxylic acid, the volatiles are removed and the reaction of the anhydride with an alcohol in presence of a stoichiometric amount of DMAP generates the desired ester.

    Carboxylic acid reactions overview (article) | Khan Academy

    Acid anhydride. Anhydrides are commonly formed when a carboxylic acid reacts with an acid chloride in the presence of a base. Let's now discuss the mechanism by which a carboxylic acid anhydride is synthesized. Similar to the Fischer esterification, this reaction follows an addition-elimination mechanism in which the chloride anion (Cl -).
