Green and Eco-Friendly Synthesis of ۲-Amino-۳-Cyano-۴H-Chromene Derivatives via Eggshell/Fe۳O۴ as a Biodegradable Polymer Matrix Nanocomposite

In this study, Eggshell/Fe۳O۴, a new biodegradable nanocomposite from natural source compounds, was synthesized and utilized to synthesize ۲-amino-۳-cyano-(۴H)-chromene derivatives via green and eco-friendly conditions. The characterization of nanocomposite was done by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), and Vibrating Sample Magnetometer (VSM). The green and biodegradable catalyst, easy recovery, reusability of catalyst, and simple workup with quantitative yields are considerable advantages of this method.
