The product of each of the given reaction sequence is to be determined. Concept introduction: A molecule that consists of a ketonic group on the β- carbon atom of an ester is generally known as β- keto ester. In such structures there is the presence of an active methylene group between the two carbonyl groups of β- ketoester. Diethyl malonate and ethyl acetoacetate are some examples of β- keto esters. These β- keto esters undergo alkylation. The resulting alkylated β- keto ester results in the formation of ketone after hydrolysis followed by decarboxylation.
