Abstract:

CuO NPs were fabricated by green route employing Epipremnumaureum (money plant) plant leaves extract. Formation of CuO NPs was confirmed by EDS, TEM, UV, XRD analysis and their morphology was studied by SEM. SEM images of nanocrystalline catalyst reveal the diffused, rod like spiky grains having distinct arrangement onto the surface. Catalytic activity of CuO NPs was explored for pseudo three component reaction of salicylaldehyde and dimedone lead to an extremely simple, ecofriendly method for one pot synthesis of 1-oxo-hexahydroxanthenes in ethanol: water (3:7: v/v) at room temperature.
