“…29 The synthesized CuO NPs was employed as an appropriate nanocatalyst for ligandfree N-arylation of indole and aniline via Ullmann-type C-N coupling reactions. A biogenic synthesis method of luminescent CuO NPs via peel extracts of Musa acuminate was reported by Chaudhary et al 30 They employed the distinctive optical and luminescence properties for sensing application for heavy metal ions using spectrophotometric analysis method. Hekmati et al prepared CuO NPs through a biological procedure using the Rosa canina fruit extract as a capping and reducing agent.…”

Aza-Michael addition is one of the most exploited reactions in organic chemistry. It is regarded as one of the most popular and efficient methods for the creation of the carbon-nitrogen bond, which is a key feature of many bioactive molecules. Herein, we report the synthesis of CuO nanoparticles by an alkaline hydrolysis process in the presence of the flower extract of Lantana camara, an invasive weed, followed by calcination in air at 400 C. Microscopic results indicated that the plant extract played an important role in the modulation of the size and shape of the product. In the presence of extract, porous CuO nanostructures are formed. While mostly aggregated rod-shaped CuO nanostructures are formed in the absence of extract. The products are pure and highly crystalline possessing the monoclinic phase. The CuO nanoparticles have been used as a catalyst in the aza-Michael addition reaction in aqueous medium under ultrasound vibration. The product yield is excellent and the catalyst is reusable up to the fifth cycle. The catalyst system can be extended to various substituted substrates with excellent to moderate yields.

Plant-mediated nano-fabrication is a new area of nanotechnology that is preferred to traditional methods due to its advantages in terms of safety, cost efficiency, environmental friendliness, and biocompatibility. In the current study, copper chloride and copper sulphate are used as precursor materials to examine the effectiveness of green synthesized copper oxide nanoparticles using the plants Bryophyllum pinnatum (lam.) and Polyalthia longifolia (Sonn.) . Comparative study on the efficiency of the synthesized Copper oxide nanoparticles against each precursor has been studied. Different spectroscopic and microscopic characterization techniques such as UV- Visible spectrophotometer, X- ray powder diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), Scanning Electron Microscope (SEM) were performed to confirm the presence of copper oxide nanoparticles. UV –vis spectrophotometer results confirmed the existence of copper oxide nanoparticles using Copper chloride and Copper sulphate precursor showed absorption at 235nm and 575nm respectively. X- Ray Diffraction results showed crystalline structure of the particles with three peaks at (111), (200) & (220) which confirmed the presence of copper oxide nanoparticle for both the precursors. FTIR results supported the existence of several functional groups involved in capping, reducing, and stabilizing copper oxide nanoparticles. The SEM image showed that the copper oxide nanoparticles were spherical in shape and ranged in size from 40 to 90 nm. Further, the Anti-fungal and Anti-bacterial activity of the synthesized nanoparticle for both the copper chloride and copper sulphate precursor were studied. The Study shown maximum zone of inhibition at 100µg/ml as 18mm and 25mm respectively against Galactomyces geotrichum. As a result of the high biological potentials and powerful Antifungal activity, the green synthesized copper oxide nanoparticles can be exploited in phytopathology to combat plant infections.
