Benzoin condensation

Solution :ALDEHYDES having `alpha`-H ATOM, when TREATED with ALUMINIUM ethoxide ( in place of NaOH or KOH), undergo CANNIZZARO type of reaction with a difference that the product isolated is an ester rather than salt of acid or alcohol. Such reaction in called Tischenko reaction.
`underset"Acetaldehyde"(2CH_3CHO) overset(Al(OC_2H_5)_3)to [CH_3COOH +CH_3CH_2OH] to underset"Ethyl acetate"(CH_3COOC_2H_5)`
