WebApr 4, 2024 · Perkin reaction is an organic reaction which is used to make cinnamic acids. It gives $\alpha ,\beta - $ unsaturated aromatic acid by the aldol condensation of an aromatic aldehyde and acid anhydride. This reaction occurs in the presence of alkali, which acts as a base catalyst in the reaction. So basically this is an aldol reaction. The Perkin reaction is an organic reaction developed by English chemist William Henry Perkin that is used to make cinnamic acids. It gives an α,β-unsaturated aromatic acid or α-substituted β-aryl acrylic acid by the aldol condensation of an aromatic aldehyde and an acid anhydride, in the presence of an … See more Clear from the reaction mechanism, the anhydride of aliphatic acid must contain at least 2 α-H for the reaction to occur.
