1. NaOEt CO₂Et 2. H3O+ 3. heat Br H3C H₁C CO₂Et CO₂H CO2 + EtOH The malonic ester synthesis is a carbonyl alkylation reaction. It is used to prepare carboxylic acids from primary alkyl halides, lengthening the carbon chain by two atoms. Thus, the product can be visualized as being a "substituted acetic acid." The reaction consists of three steps: generation of the enolate anion followed by SN2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation.
