Abstract

In this research, we report a novel and green magnetic nanocatalyst; Fe₃O₄@SiO₂@Vitamin C@Fe₂O₃ for clean synthesis of 3-amino-1-aryl-1H-benzo[f]chromene-2-carbonitriles with high-yield in water as solvent at room temperature. The nanocatalyst is stable under the synthetic conditions and it can be reused several times without considerable reduction in its catalytic activity. The catalyst structure was characterized by using various analytical techniques; SEM, FT-IR, thermogravimetric analysis (TGA), UV-vis spectroscopy, VSM and EDS. Also, the products were separated and characterized by determining their melting points, IR spectra and compared to those of the authentic samples.  Environmentally friendly, availability, high catalytic activity and ease of separation are the main reasons for using Fe₃O₄@SiO₂@Vitamin C@Fe₂O₃ as a green catalyst.
