摘要：

In this study, 1-(1-alkylsulfonic)-3-methylimidazolium chloride as a new, green, and reusable Br?nsted acid catalyst was prepared. In this protocol, we used for the regioselective ring-opening reactions of various epoxiodes with sodium azide to afford the corresponding b-azido alcohols in excellent yields and short reaction time under mild and neutral reaction conditions. This method offers several advantages including excellent regioselectivity, clean reactions, simple work-up procedure, a recyclable catalyst,and use of an eco-friendly catalyst.
