Schiff's reaction and Tischenko reaction
(a) Schiff's reaction: this reaction restores pink colour to Schiff's reagent (aqueous solution of p-rosaniline hydrochloride decolourised through passing sulphur dioxide).
(b) Tischenko reaction: On heating benzaldehyde along with aluminium alkoxide (ethoxide) and a little of anhydrous AlCl3 or ZnCl2, it goes through an intermolecular oxidation and reduction (such as aliphatic aldehydes) to make acid and alcohol respectively like and react to produce benzyl benzoate (an ester).
