Abstract
Nitrogen-doped Graphene Quantum Dots (N-GQDs) are effective and the most recent expansion to carbon nanomatetials family and guarantee a wide range of novel applications that can be used especially in design of modern hybrid catalyst such as metal-organo catalyst. In this research paper, we report a concise and facile preparation of a series of the furo[3,2-c]coumarin compounds via multicomponent reaction of 2,4′-dibromoacetophenone, benzaldehyde, and 4-hydroxycoumarin under ultrasound irradiation conditions. Nanocomposite catalyst were characterized with powder X-ray diffraction (XRD), transmission electron microscope (TEM), Field emission scanning electronic microscopy (FE-SEM), Energy dispersive X-ray (EDX), and Fourier-transform infrared (FT-IR) spectroscopy. The concise and facile protocol suggests momentous advancement by simple generation of metal-organo catalyst in respect to resolve the issue of utilizing harsh catalysts. This protocol provides several advantages including facile workup, excellent yields, short reaction times, use of ultrasound source as a clean method, recoverability of the catalyst, and little catalyst loading.
