Amine-functionalized biochar as a green and recyclable nanocatalyst for the efficient synthesis of 1,8-naphthyridine and 2-amino-4 H -chromene derivatives
RSC Advances Vol. 16, No. 41, 49055–49067
چکیده
-chromene derivative was obtained in 97% yield within 7 min. The catalyst showed high recyclability and only a slight decrease in its corresponding activity was observed after several cycles of use, which indicates its structural stability and recyclability. Amine-enriched biochar is a highly effective, eco-friendly, and reusable (5-cycle) nanocatalyst for the synthesis of critical pharmaceutical heterocycles. It is a greener substitute for conventional catalysts and it helps researchers to move forward with green synthesis approaches.
