Synthesis of nitrogen (N) and copper oxide (CuO) co-doped reduced graphene oxide as an efficient nanocatalyst for reduction of nitroarenes and synthesis of 1, 8-dioxodecahydroacridine derivatives

The present study focuses on developing a robust reduced graphene oxide-based heterogeneous catalyst by synthesizing it with the doping of nitrogen (N) and copper oxide (CuO). Various techniques were used to characterize the green catalyst, such as FTIR , PXRD , TGA , RAMAN, TEM , SEM, and EDX . The catalyst was utilized in the production of various biologically important aniline derivatives through the reduction of nitroarenes with NaBH 4 and the synthesis of 1,8-dioxodecahydroacridine derivatives via one-pot, multi-component condensation of dimedone , various aromatic aldehydes , and anilines / NH 4 OAc. Some key features of the current catalytic system include a high yield (up to 96 % and 97 %, respectively), quick reaction time (20 min and 1 h, respectively), low catalyst loading (10 mg for each), broad functional group tolerance, and a simple work-up process.
