The Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction that involves the base-induced disproportionation of an aldehyde lacking a hydrogen atom in the alpha position . Learn the Cannizzaro reaction mechanism with stepwise explanation, cross Cannizzaro , key examples, and exam tips for Chemistry students. Cannizzaro reaction , examples, mechanism, and its applications have been discussed here. The aldehydic compounds having no α-hydrogen atoms in presence of strong base undergo disproportionation to form an equal amount of corresponding alcohol and carboxylic acids. Such a reaction is called the Cannizzaro reaction . Some of the examples of the Cannizzaro reaction involve the reduction of benzaldehyde, formaldehyde, trimethyl acetaldehyde, etc. Cannizzaro Reaction This redox disproportionation of non-enolizable aldehydes to carboxylic acids and alcohols is conducted in concentrated base. α-Keto aldehydes give the product of an intramolecular disproportionation in excellent yields.
