The synthesizedFe3O4@APTES@isatin-SO3Hmagnetic nanoparticles (MNPs) were characterized using the energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), and thermogravimetric(TGA) analysis. The Fe3O4@APTES@isatin-SO3HMNPs performed efficient catalytic activity as a magnetically recyclable heterogeneous catalyst for one-pot, condensation reaction of 1,2-dicarbonyl compounds and o-phenylen diamines in ethanol at room temperature to afford quinoxaline derivatives.}, keywords = {Fe3O4@APTES@isatin-SO3H,quinoxaline, O-phenylen diamines,1, 2-dicarbonyl,nanocatalyst}, url = {https://www.echemcom.com/article_104092.html}, eprint = {https://www.echemcom.com/article_104092_f079a004c68f8be38bc0affe137b196c.pdf} }
