摘要：

In this study, construction and characterization of a new inorganicorganic hybrid nanomaterial, and its usage as an efficacious catalyst for the solvent-free fabrication of 2-amino-4H-chromenes have been reported. The chromenes (10 examples) were procured in short reaction times (10-20 min) and high yields (89-98%) through the onepot multi-component reaction of malononitrile, 1-naphthol and aryl aldehydes. The nanocatalyst was reusable for two times without significant loss of its activity. Characterization of the nanomaterial titled [SiO2@Si(CH2)3-(4,4 '-bipyridine)-1,1'-diium][FeCl4][H2PO4] (SCBFH) was done by analyses such as elemental mapping, XRD (X-ray diffraction), FT-IR (Fourier-transform infrared spectroscopy), Raman, FE-SEM (field-emission scanning electron microscopy), TG (thermogravimetric), and EDS (energy-dispersive X-ray spectroscopy).
