A simple and efficient method for the conversion of oxiranes to thiiranes using ammonium thiocyanate (NH4SCN) under solvent- and catalyst-free conditions is described. These conditions enable clean and fast conversion of oxiranes to the corresponding thiirane.

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.
Magnetically separable nano CuFe2O4: an ef?cient and reusable heterogeneous catalyst for the green synthesis of thiiranes from epoxides with thiourea

, p. 537 - 545 (2016/10/03)
The magnetically separable nano CuFe2O4 was prepared and used as an efficient heterogeneous catalyst for conversion of various epoxides to the corresponding thiiranes with thiourea in refluxing ethanol. The reactions were completed within 34?45 min to give thiiranes in 80?95% yields. The utilized nano CuFe2O4 can be reused for several times without losing its activity.
