TISCHENKO REACTION (detailed mechanisms with solved examples) YouTube
Mechanism of cannizzaro reaction mechanism step 1. Several other mechanisms have been proposed for this reaction, including a radical mechanism as well as a mechanism involving an aluminium hydride species. A nucleophile such as a hydroxide ion is used to attack the carbonyl group of the given aldehyde, causing a disproportionation reaction and giving rise to an anion carrying 2 negative charges. For the tishchenko reaction, al (oet)3 is used as reagent where an aldehyde is oxidized as well as reduced, so it's a redox reaction.
