摘　　要：报道了4-取代-1-磺酰基-1,2,3-三氮唑在绿色溶剂中的催化水解反应,以1 mol%硫酸铜作为催化剂,在水/PEG-400混合溶剂中以较高的收率高效合成了4-取代-2H-1,2,3-三氮唑.该方法为制备2H-1,2,3-三氮唑类化合物提供了一种绿色、简单、有效的方法.此外,还用一锅法对2H-1,2,3-三氮唑进行了溴化、芳基化、烷基化的探索,效果良好.The hydrolysis of 4-substituted 1-sulfonyl-1,2,3-triazoles induced by a catalytic amount of copper sulfate in the green solvent of H2O/PEG-400 was reported,providing a wide range of 4-substituted-2H-1,2,3-triazoles in excellent yields.The approach provides a green,simple and effective method for the preparation of 2H-1,2,3-triazole compounds.Bromination,arylation,and alkylation on 2H-1,2,3-triazoles by the one-pot method were also explored.
