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.

Nickel and magnesium ferrite magnetic nanoparticles were fabricated and applied as efficient and reusable catalysts in the solvent-free conversion of various epoxides to the corresponding thiiranes with ammonium thiocyanate under oil bath (60°C) conditions. NiFe2O4 and MgFe2O4 nanoparticles can catalyze the reactions at short times in high to excellent yields. The catalysts can also be recovered easily using an external magnetic field and be reused four times without any significant loss of activity.
A green protocol for rapid and efficient conversion of epoxides to thiiranes using alumina immobilized thiourea at solvent-free conditions

Solvent-free conversion of various epoxides to the corresponding thiiranes was carried out successfully with alumina-immobilized thiourea at room temperature. The reactions were completed within 2-9 min to give thiiranes with 83-98% yields. The utilized alumina can be reused for several times without losing its activity.
