Title: Synthesis and characterization of Cu-modified ox-g-C3N4 nanosheets as an electrode for green synthesis of phenyl Benzofuran derivatives via C–H functionalization to C–O and C–C bond formation with an electrochemical oxidation system
Abstract: In this study, our primary objective was to synthesize and characterize a copper nanoparticle-modified oxidized graphite carbon nitride (ox-g-C3N4). This modified ox-g-C3N4 material was utilized as a reusable catalyst for the environmentally friendly production of benzofuran 4(a-j) derivatives through C–H activation using an electrochemical oxidation system. The desired derivatives were obtained by reacting 2-bromophenol 1(a-c) with ethynylbenzene 2(a-g) yielding high yields ranging from 89 to 94%. The modified Cu/ox-g-C3N4 nanocomposite was thoroughly examined. using different analytical techniques, including thermogravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), IR Fourier-transform infrared spectroscopy (FT-IR), Brunauer–Emmett–Teller (BET) analysis, cyclic voltammetry (CV), and X-ray diffraction (XRD) spectroscopy, and ultraviolet (UV) spectroscopy. The comprehensive identification was conducted in a comparative manner, allowing for a thorough understanding of the nanocomposite's properties. By employing this nanocatalyst, we implement a greener synthesis approach that reduces the need for dangerous and toxic substances, while reducing waste generation by promoting reuse. The synthesized products in this research were subjected to characterization utilizing techniques such as melting point analysis, CHN analysis and 1HNMR spectroscopy. These analytical methods were utilized to confirm the identification and assess the purity of the benzofuran compounds synthesized 4(a-j).
