Esters, like aldehydes and ketones, are weakly acidic. When an ester with an alpha hydrogen is treated with one equivalent of a base such as sodium ethoxide, a reversible condensation reaction occurs to yield a β−keto ester product. This reaction between two ester components is known as the Claisen condensation reaction

Carboxylic acids are just one member of a class of acyl derivatives, RCOY, where the acyl group is bonded to an electronegatives substituent -Y that can act as a leaving group in substitution reactions. Numerous acyl derivatives are possible, but we’ll be concerned only with four of the more common ones, in addition to carboxylic acids themselves: acid halides, acid anhydrides, esters, and amides
