Perkin Reaction

a method of synthesizing β-arylacrylic acids (cinnamic acid and its derivatives and analogues) by reacting aromatic aldehydes with carboxylic acid anhydrides in the presence of a basic catalyst, such as alkali salts of carboxylic acids, carbonates of alkali metals, or tertiary amines:
