Green synthesis approach for quinoxalines and their derivatives utilizing waste orange peel extract CuO nanoparticles.

The eco-friendly synthesis of quinoxaline and its derivatives was achieved using copper oxide nanoparticles (CuONPs). These green CuO NPs were prepared utilizing a waste orange peel extract, which acts as both a reducing and stabilizing agent. The nanoparticles were then used as a renewable catalyst in the formation of quinoxaline and its derivatives. Characterization of the green CuO NPs was performed using PXRD and SEM techniques. This approach provides numerous benefits, including high yields, straightforward methodology, catalyst recyclability and an uncomplicated workup process.
