Copper nanoparticles supported on graphitic carbon nitride (Cu₂O [email protected] g-C₃N₄) make a photoactive catalyst that has been developed for the preparation of ynone, aminoindolizines, and pyrrolo [1, 2-a] quinoline in mild and sustainable conditions. The catalyst is well characterized by various analytical techniques. The reaction can be completed using visible light more smoothly without the requirement of any other external sources of energy. The Cu₂O [email protected] g-C₃N₄ material is found to be a more efficient, active, and reusable catalyst for the synthesis of ynone, aminoindolizines, and pyrrolo [1, 2-a] quinoline. Green chemistry metrics such as atom economy (AE) and E-factor are calculated for the reaction, and it is found that the present protocol is more facile and follows the green chemistry principles.
