The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2.

H3 C H2Br Br2, H30* HC X CH3 HzC CH3 H3C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl, Br, or 12, under acidic conditions. Using Br2 under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Not started curved arrows to show the movement...
