Catalytic application of a novel nano-catalyst of CuO/MnO2 for the synthesis of propargylamine derivatives

In the present research, an efficient process for the synthesis of propargylamine derivatives catalyzed by a novel nanocomposite of CuO/MnO2 is reported. CuO/MnO2 nano-catalyst was synthesized by the co-precipitation process and characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction(XRD), ICP-OES and BET surface area analysis. A broad range of aromatic aldehydes was reacted with amines and phenylacetylene to produce the corresponding propargylamines. The CuO/MnO2 nano-catalyst is recyclable up to 7 repeated runs and it can be easily recovered by simple filtration. The present method affords additional advantages such as straightforward procedure, ease of workup, clean method and moderately short reaction times
