WebThe Cannizzaro reaction is a base-catalyzed disproportionation reaction of an aldehyde, devoid of α-H atoms, into the corresponding carboxylic acid and alcohol. Aldehydes with α-H atoms do not undergo the Cannizzaro disproportionation, as the aldol reaction is much faster. In the aldol reaction, C–C bond formation occurs by addition of the ... WebThe Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction which involves the base -induced disproportionation of two molecules of a non- enolizable aldehyde to give a primary alcohol and a carboxylic acid.
