In the reaction of conversion of nitriles to amides, more particularly, but not exclusively, acrylonitrile to acrylamide, the improvement consisting in the adoption, as a catalyst, of a copper-based catalyst which is prepared by reacting an organic copper chelate with aluminum-alkyl and/or an aluminum hydride. Higher yields and higher selectivity are obtained over the usual copper-based catalysts.
