WebSep 26, 2024 · In the functionalization with 4-dimethylamino cinnamic acid, a reaction yield of 99% was achieved, and two synthetic routes can be followed: (i) the molar ratio of cinnamic acid derivative: EDC (1:5) and the molar ratio cinnamic acid derivative:pigment (10:1) in DMF at room temperature during 1 h under stirring or (ii) ... 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).
