Aldehydes with or without α-hydrogen atom can be made to undergo Cannizzaro type of reaction, if reaction is carried out in presence of almunium ethoxide. But in such case, acid and alcohol react together to form ester as the final product.
\(CH_3CHO+CH_3CHO \xrightarrow {Al(OC_2H_5)_3}CH_3COOH+\)
\(CH_3CH_2OH \longrightarrow \underset {Ethyl\,acetate}{CH_3COOC_2H_5}\)
