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. (C) 2019 Elsevier Ltd. All rights reserved.
