The Tishchenko reaction is an organic chemical reaction that involves disproportionation of an aldehyde lacking a hydrogen atom in the alpha position in the presence of an alkoxide.[1] The reaction product is an ester. Catalysts are aluminium alkoxides or sodium alkoxides.

In the related Cannizzaro reaction the base is sodium hydroxide and then the oxidation product is a carboxylic acid and the reduction product is an alcohol.

Examples

The Tishchenko reaction: benzaldehyde reacts to benzyl benzoate, the catalyst is generated in situ from sodium and benzyl alcohol
