Abstract

A new magnetic nanomaterial, namely [Fe3O4@SiO2@Si(CH2)3–NMe2–(CH2)2–NMe2–SO3H][Cl]2 (FSCNSC) was synthesized, and characterized by energy-dispersive X-ray spectroscopy (EDS), elemental mapping, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), FT-IR, vibrating-sample magnetometery (VSM), thermogravimetric (TG) and derivative thermogravimetry (DTG) analyses. Afterward, it was used as a highly effective catalyst for the synthesis of bis(6-amino-1,3-dimethyluracil-5-yl)methanes under solvent-free conditions. FSCNSC was better than many of the reported catalysts for the synthesis of this category of uracil derivatives in terms of the reaction conditions, the reaction times, and yields.
