چکیده مقاله :
Design and synthesis of green and recyclable catalysts in order to improve the efficiency of organic chemistry reactions is a significant challenge [1]. 2-amino-4H-chromenes are known to have diverse biological and pharmacological activities [2]. In this study, first, graphitic carbon nitride (g-C3N4) /biochar nanosheets with high surface area and chemical stability were synthesized. Afterwards, the surface of this nano-substrate was modified with polyethyleneimine to obtain g-C3N4 biochar/PEI. The synthesis of 2-amino-4H-chromenes derivatives was performed in reflux (water: ethanol) condition, with high yield. The advantages of this reaction include easy catalyst separation and reusability thanks to its heterogeneous nature, with good to excellent efficiency, and finally short reaction time.
