  • Decarboxylation is the removal of carbon dioxide from carboxylic acids.

    • R= alkyl, aryl

    Decarboxylation of simple carboxylic acids requires very high temperatures, at which the organic product often decomposes. In contrast, β-ketoacids undergo decarboxylation upon warming.


    The molecule of a β-ketoacid is stabilized by an intramolecular hydrogen bond that creates a six-membered ring, allowing the reaction to occur via a relatively stable, six-membered cyclic transition state.
