In this study, we synthesized Ag supported on hydroxyapatite-core-shell-γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ag NPs) as a new, lewis acid, and reusable heterogeneous nancatalyst. Then, it was successfully used for the synthesis of β-azido alcohols and β-thiocyanohydrins from the regioselective conversation of some epoxides by azide and thiocyanate anions in water. The reaction afforded the corresponding products with high regioselectivity under mild reaction conditions.
