A Novel Approach in Cinnamic Acid Synthesis: Direct Synthesis of Cinnamic Acids from Aromatic Aldehydes and Aliphatic Carboxylic Acids in the Presence of Boron Tribromide Cinnamic acid is a monocarboxylic acid that consists of acrylic acid bearing a phenyl substituent at the 3-position. Principle: The reaction between aromatic aldehyde and an aliphatic anhydride capable of providing an ‘active methylene‘ moiety in the presence of a basic catalyst, such as: acetate ion and a hydronium ion, which yields an α, β-unsaturated carboxylic acid and a mole of acetic acid i.e. J.
