The Utilization of Fe₃O₄ nanocatalyst in modifying cinnamaldehyde compound to Synthesis 2-amino-4H-chromene derivative

Fe₃O₄ nanoparticles have got more attention in their application as catalyst. This research aims to utilize Fe₃O₄ as nanocatalyst in modifying of cinnamaldehyde compound. In this study, Fe₃O₄ nanoparticles were synthesized by co-precipitation method using Fe²⁺ and Fe³⁺ ions and characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results of the characterization supports that Fe₃O₄ nanoparticles were successfully synthesized. Afterward, Fe₃O₄ would be applied in modifying of cinnamaldehyde compound. The results of the reaction were analyzed its absorbance, functional group, and molecular weight using UV/Vis Spectrophotometry, FT-IR and GC-MS. From the results of the synthesis and characterization, one cinnamaldehyde modified compounds was obtained, namely 2-amino-4-styryl-4H-benzo @ [h]chromene-3-carbonitrile (Compound 1). From the yield of the reaction, a significant difference was found between the reaction with and without catalyst.
