Tishchenko reaction A variant of the Cannizzaro reaction, known as the Tischenko reaction is a disproportionate reaction  of an Aldehyde lacking a hydrogen atom in the alpha position in the presence of an Alcoxide. Catalyst are  aluminium alkoxides  or  sodium alkoxides .  In this reaction the alcohol and acid products combine to form an  ester .
