Abstract
Cupreous catalysts containing (a) copper prepared by reducing copper oxide, (b) reduced copper oxide, or (c) copper oxide have been found to be excellent heterogeneous catalysts for the conversion of nitriles in the presence of water to the corresponding amides. High conversions and yields are obtained with little or no deleterious by-products.
