Ceria and Modified Ceria: A Reusable Catalyst for the Green Synthesis of 2,3-diphenyl Quinoxaline at Room TemperatureBy Sunaja Devi K.R, Nagesh K, Sreeja P. B, Riya Datta
Abstract: Simple, highly versatile and efficient synthesis of 2,3-diphenylquinoxalines is achieved from benzil and o-phenylene diamine using ceria and modified ceria as the catalyst. Modification of ceria is done using different weight percentage of zirconia. The catalysts are characterized by XRD, FT-IR, BET surface area, TGA and EDX-SEM. The advantages of this method are short reaction times, milder conditions and easy work-up. The product could be separated from the heterogeneous catalyst …
