In this research, design and synthesis of Fe3O4@APTES@MOF-199magnetic 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 X-ray 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 in84-97%yields. The recyclability of the catalyst was evaluated up to 5 times, with no loss in catalysis activity. Manuscript profile

Easily synthesized1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid {[MOEI]-BSA} as a novel catalyst efficiently promoted the synthesis of quinoxaline derivatives via condensation of various diamines with 1,2-dicarbonyl compounds at room temperature conditions in ethanol. This research provides a new method for the synthesis of quinoxalines in good to excellent yields with little catalyst loading. The catalyst could be recycled and reused several times without any loss of efficiency. Manuscript profile
