Cannizzaro Reaction: Examples, Mechanism, and Application
Mechanism of Cannizzaro Reaction. The reaction begins with a hydroxide attack on the carbonyl carbon followed by deprotonation to give a dianion. The unstable dianion releases a hydride anion, which attacks another molecule of aldehyde. In this process, the dianion converts to a carboxylate anion and the aldehyde to an alkoxide.
