چکیده

In this study, we synthesized Ag supported on hydroxyapatite-core-shell- γ -Fe 2 O 3 nanoparticles ( γ -Fe 2 O 3 @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.
