Dehydration may be accompanied by decarboxylation when an activated carboxyl group is present.
WebThe way that it works is that a beta-carbonyl carboxylic acid can decarboxylate in the presence of heat. What this does is it produces CO2 gas as a byproduct. It evolves out of the material. Now what a beta … WebSubsequent acid-catalyzed hydrolysis with heat leads to decarboxylation of the dicarboxylic acid to give 3-ethylpentanoic acid.
