Abstract
In this investigation, the extract of Rhus coriaria utilized for preparation of Fe3O4 nanoparticle using a green approach. This method is clean, non-toxic and eco-friendly. The green synthesized nano-catalyst was described by means of SEM, EDX, elemental-mapping point exploration, X-ray diffraction, FT-IR, and UV-Vis analysis methods. The biosynthesized magnetite nanoparticles are affordable and reusable. Accordingly, this allows Fe3O4 nanoparticle catalyst to be utilized in the synthesizing of some new 2-naphthol bis-Betti bases by condensation of substituted aromatic aldehydes, 2-naphthol and p-phenylenediamine by one-pot process reaction. The products have been described using FT-IR, 1H-NMR, 13 Karmakar, B.; Nayak, A.; Banerji, J. A Clean and Expedient Synthesis of Spirooxindoles in Aqueous Media Catalyzed over Nanocrystalline MgO. Tetrahedron Lett. 2012, 53, 5004–5007.[Crossref], [Web of Science ®] , [Google Scholar]C-NMR, and mass-spectral data. In vitro anti-bacterial and anti-fungi evaluation of bis Betti bases were achieved against gram-positive and gram-negative bacterial strain by means of the well diffusion method. It has been observed that some of these bis Betti bases possess potent anti-bacterial characteristics against these bacteria.
