Abstract
Cobalt(II) catalyses the coupling of 1,3- and 1,4-dicarbonyl compounds with various aldehydes in the presence of acetonitrile to give β-acetamido ketones and furan amides respectively. The outcome of these reactions is controlled by the reaction atmosphere as aromatic aldehydes react to give β-ketoamide in the presence of nitrogen, whereas the reaction with aliphatic aldehydes gives the later product only in the presence of oxygen atmosphere.
