Green synthesis of 1,4-quinone derivatives and evaluation of their fluorescent and electrochemical properties

Abstract

Green synthesis of some 1,4-quinone derivatives by conventional and solvent free microwave assisted methods has been reported. The microwave assisted method resulted in higher percentage yield at shorter time compared to the conventional one. In the conventional method environmentally friendly solvent was used and the results were compared with other solvents. When water was used as a solvent the reaction exhibited higher yield than other solvents like ethanol. The solvent free method under microwave irradiation method yielded the highest yield compared to the conventional methods. The resultant compounds were analyzed by UV–Vis, FT-IR, 1H and 13C NMR spectroscopy. The synthesized quinone derivatives exhibited the fluorescent and electrochemical properties.
