1,4‐Disubstituted 1,2,3‐triazoles are prepared through the 1,3‐dipolar cycloaddition of propargyl (alcohols/amines) and aryl azides in the presence of a mixture of Cu(OAc)2.H2O and NaAs as the catalyst. This method offers the advantages of mild experimental conditions, operational simplicity, and high‐to‐excellent reaction yields.
1,4-二取代的1,2,3-三唑是在Cu(OAc)2 .H 2 O和NaAs的混合物存在下,通过炔丙基(醇/胺)和芳基叠氮化物的1,3-偶极环加成制备的作为催化剂。该方法具有温和的实验条件,操作简便和高至出色的反应收率的优点。
