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.
