Abstract
The magnetically separable CuFe2O4/Mg(OH)2 nanocomposite was prepared and characterized by FT-IR, XRD, SEM, EDS, and VSM techniques. The synthesized nanoparticles were used as a new and efficient heterogeneous catalyst for the conversion of various epoxides to the corresponding thiiranes with thiourea in water solvent at room temperature. The reactions were completed within 1–3.7 h to give thiiranes in 70–99% yields. The applied CuFe2O4/Mg(OH)2 nanocomposite was separated easily using an external magnet and reused for several times without any considerable loss of activity.
