Synthesis and Characterization of Fe3O4@APTES@MOF-199 Magnetic Nanocatalyst and Its Application in the Synthesis of Quinoxaline Derivatives

In this research, design and synthesis of Fe3O4@APTES@MOF199magnetic nanocatalyst nanoparticles as a novel, recyclable and heterogeneous catalyst was developed. The magnetic nanocatalyst was analyzed using various spectroscopic methods such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), powder Xray diffraction (XRD), energy dispersive X‐ray (EDX), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM). The particle size of the nanocatalyst is about 15-96 nm. In addition, magnetic nanocatalysts have been successfully applied to the synthesis of quinoxaline derivatives with a range of derivatives. The crude compounds were isolated in 84-97% yields. The recyclability of the catalyst was evaluated up to 5 times, with no loss in catalysis activity.
