Ketone Formation by Acetoacetic Ester Synthesis
Description
Acetoacetic ester synthesis is a way to make ketones from alkyl halides and β-keto esters. It uses an alkoxide base to remove the acidic proton from the β-keto ester. That forms an enolate ion, which is doubly stabilized.
The enolate then reacts with an alkyl halide by an SN2 process. This step c...

Transcript
In acetoacetic ester synthesis, β-keto esters containing acidic α protons are converted to substituted acetones in the presence of a base via an alkylated ester intermediate.
The reaction begins with an alkoxide base abstracting the α proton of the substrate to generate a nucleophilic enolate ion.
The carbanion then attacks t...
