Synthesis of a new Ag supported on hydroxyapatite-core-shell-γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ag NPs) and its application as a Lewis acid catalyst in the preparation of β-azidoalcohols and β-thiocyanohydrins from epoxides %K Ag supported %K β-azido alcohols %K Ring Opening %K Regioselective %K Lewis acid %R 10.22034/AJGC/2020.1.4 %X 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. %U https://www.ajgreenchem.com/article_83853_d3aaa19f5efe8e5679666702333b2f05.pdf
