    Acetaldehyde is an industrially important solvent used as an intermediate for the synthesis of a wide range of compounds. On oxidation it forms acetic acid and ethanol on reduction. The interaction of Criegee intermediate (CH2OO) with acetaldehyde has been measured. Its effect as a neuroactive agent has been studied. Alkynylation reaction of acetaldehyde by asymmetric catalysis has been reported.

    Application

    Acetaldehyde may be used in the synthesis of 1,3-diamines by one-pot cross double-Mannich reaction and β-amino aldehydes by proline-catalyzed Mannich reaction.
