Preparation and characterization of magnetically separable MgFe2O4/Mg(OH)2 nanocomposite as an efficient heterogeneous catalyst for regioselective one ‐pot synthesis of β‐chloroacetates from epoxides

Magnetically separable MgFe2O4/Mg(OH)2 nanoparticles were fabricated and characterized. These nanoparticles were used as a catalyst for regioselective one ‐pot synthesis of β‐chloroacetates from epoxides in EtOH at room temperature giving high to excellent yields. The nanocatalyst was easily separated and reused several times without any significant loss of efficiency or magnetic property. Magnetically separable MgFe2O4/Mg(OH)2 nanoparticles were fabricated and characterized using various techniques. These nanoparticles were used as a new catalyst for regioselective one ‐pot synthesis of β‐chloroacetates from epoxides in the presence of NiCl2⋅6H2O and acetic anhydride. All reactions were carried out in ethanol at room temperature within 22 –80 min giving the β‐chloroacetates in high to excellent yields. The nanocatalyst was easily separated using an external magnet and reused several times without any significant loss of efficiency or magnetic property.
