The complete, detailed mechanisms for the reactions in Equation 21-39 and 21-40 are to be drawn. Concept introduction: In Claisen condensation is a carbon–carbon bond has formed. In this reaction, in presence of a strong base, the two esters or one ester and another carbonyl compound reacts to form a β-keto ester or a β-diketone . The process of replacing the organic group of an ester with the organic group of an alcohol is termed as transesterification. The transesterification reaction is catalyzed by the addition of base or an acid. The reacton can be reversed. With the help of water and a base, the carboxylic acid and an alcohol can be obtained. This reaction is termed a saponification.
