Cinnamic acid reaction
WebProposed mechanism of the reaction between the reactants benzaldehyde 1a and malonic acid 3 towards the product cinnamic dicarboxylic acid 4a catalyzed by in situ formed hydrobenzamide 2a. First, a proton from the α-carbon of the reactant malonic acid 3 is transferred to an imine in hydrobenzamide 2a (step iv).
