Synthesis and characterization of graphitic carbon nitride supported Tris(hydroxymethyl)aminomethanes) g-C3N4/THAM) as a novel catalyst for the synthesis of poly hydroquinoline and pyranopyrazole derivatives

Abstract

Here, an impressive heterogeneous catalytic system g-C3N4/THAM is presented. The novel g-C3N4/THAM nanocatalysts were characterized by analyzing methods such as FT-IR, EDX, XRD, TGA, and FESEM. Afterward, the performance of fabricated nanocatalyst g-C3N4/THAM was suitably investigated in multicomponent reactions (MCRs) to synthesize 1,4-dihydropyridine and pyranopyrazole derivatives. By optimizing the reported nanocatalyst, the corresponding reaction products were obtained with excellent efficiency, and then the reversibility process was exanimated. The g-C3N4/THAM nanocatalyst is environmentally friendly and was catalyzed the reactions in the presence of ethanol as a green solvent.
