Question

Quizplus · Accepted Answer

The Claisen reaction involves the condensation of two esters or one ester and a ketone to form a β-ketoester. In this case, the reaction involves the condensation of ethyl propionate (I) and diethyl malonate (II) in the presence of sodium ethoxide. The product (III) is a β-ketoester, which is characterized by the presence of a carbonyl group (C=O) next to a CH2 group. The other products (I and IV) are the starting materials and (II) is the solvent used in the reaction.
