Environment Benign Bismuth Based Catalysts for the Expedite Regioselective Ring Opening of Epoxides Under Solvent Free Microwave Condition

Abstract

Bismuth‐based catalysts, namely Bi(PO4), (BiO)2CO3, BiF3, and Bi2(C2O4)3, are used as mild and efficient tools for the aminolysis of epoxides under solvent‐free conditions with microwave irradiation, which significantly reduced the reaction time. The catalysts employed are environment friendly, cost‐effective, and demonstrated high efficiency in terms of both high yields and regioselectivity.
