amides is catalyzed by simple copper salts. The use of homogeneous Cu(OAc)2 (1–2 mol %) was found to be effective for this transformation at 80 °C. The reaction was successful with either conventional or microwave heating. CuO and CuO/ZnO on activated carbon provided a competent reuseable heterogeneouscatalyst which could be used in a batchprocess or in flow. Copper salts are much cheaper than the precious
