Porous carbon catalysis in sustainable synthesis of functional heterocycles: An overview

Heterogeneous porous carbon (PC) materials have gained unique importance in the catalysis community due to their captivating properties, including high specific surface area, tunable porosity, and functionality. PC can play a prominent role in the sustainable synthesis of functional heterocycles, as they are a low-cost alternative while being an efficient and user-friendly material. This review examines the preparation and applicability of these carbonaceous materials used as catalysts or support for biologically active heterocycles synthesis, including hydrogenation, oxidation, oxidative dehydrogenation, cross-coupling, and other organic reactions. Moreover, the challenges, potential future development directions, and opportunities in the synthesis of potent bioactive heterocycles over PC materials have been addressed. This review will inspire further research to explore novel PC materials and their implications in heterocyclization.
