Perkin Reaction Mechanism - In Depth Explanation and Reaction Details

WebThe Perkin reaction is an organic reaction used to convert an aromatic aldehyde and an anhydride to an α,β-unsaturated carboxylic acid using sodium acetate, a base, and an acid work-up. The regiochemistry of the … WebThe Claisen-Schmidt condensation reaction is an organic reaction in which a ketone or an aldehyde holding an α-hydrogen reacts with an aromatic carbonyl compound which does not have any α-hydrogens. This 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. The above mechanism is not universally accepted, as several other versions exist, including … See more • Benzaldehyde reacts with acetic anhydride in the presence of sodium or potassium acetate to form cinnamic acid. • One notable application for the Perkin reaction is in the laboratory synthesis of the phytoestrogenic stilbene resveratrol (c.f. fo-ti See more • Erlenmeyer–Plöchl azlactone and amino-acid synthesis • Stobbe condensation • Pechmann condensation See more carenow farmers branch
