ChemInform Abstract: One‐Step Method for the Synthesis of Aryl Olefins from Aryl Aldehydes and Aliphatic Aldehydes.

Abstract

Aliphatic Aldehydes. -The reaction of aromatic aldehydes with aliphatic ones in the presence of malononitrile proceeds via Knoevenagel products as intermediates (reaction mechanism). The mild conditions do not require a metal catalyst. AcOH can be replaced by proline or alanine with similar yields. -(BORATE*, H. B.; GAIKWAD, S. H.; KUDALE, A. S.; CHAVAN, S. P.; PHARANDE, S.
