Preparation And Characterization Of g-C3N4 @ L-Arginine As A Highly - Efficient And Recyclable Catalyst For The Synthesis of 1, 4-Dihydropyridine, 4H-Chromene, And 2, 3-Dihydro Quinazoline Derivatives

Abstract In this work, the nanocatalyst of g-C 3 N 4 @L-arginine was prepared that synthesis of it in comparison with the synthesis of other catalysts was convenient; initially, this prepared nanocatalyst was evaluated and verified by FT-IR, EDX, XRD, TGA, and FESEM analysis, and in the next step, the performance of nanocatalyst in the synthesis of 1, 4-dihydropyridine, 4H-chromene, and 2, 3-dihydro quinazoline derivatives were examined with high yield. Properties such as high thermal stability, easy separation of reaction media, use in various multicomponent reactions, and reusability have caused that this novel nanocatalyst was changed into a unique catalyst in its own age.
