MECHANISM OF CANNIZZARO REACTION * The Cannizzaro reaction is initiated by the nucleophilic attack of a hydroxide ion on the carbonyl carbon of an aldehyde molecule by giving a hydrate anion, which can be further deprotonated to give a dianion in a strongly alkaline medium. Intramolecular catalysis. Part 4. -3-Prenylated Flavanones. Pavel A. Kots, Anna V. Zabilska, Irina I. Ivanova. Origins of Life and Evolution of Biospheres. Three competitive transition states in the benzoin condensation compared to the clear rate-determining step in the Cannizzaro reaction. The Cannizzaro reaction is a redox disproportionation of aldehydes to carboxylic acids and alcohols in the presence of a a strong base.
