Decarboxylation reagent
WebCarboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation. In … WebA carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide. The reaction steps are shown below: Step 1: Deprotonation of the acid. Step 2: Nucleophilic attack by the carboxylate. Step 3: Nucleophilic attack by the amine.
