我们发展了聚乙二醇(PEG4000)支持CuI催化的Huisgen环加成反应合成三氮唑衍生物的新颖方法.在聚乙二醇(PECA000)支持CuI的催化下,芳基叠氮和末端炔的Huisgen环加成反应以较高的收率得到三氮唑衍生物.初步研究负载催化剂的回收使用情况.%An efficient synthetic method for aromatic triazoles accelerated by rpolymer-supported CuI as catalyst between organic azides and terminal alkynes has developed. Treatment of terminal alkynes with benzyl azide or aryl azides in water smoothly gave the Huisgen 1, 3-dipolar cycloaddition products, triazoles. The novel Cu (Ⅰ) complex has shown good activity and stability after eight catalytic cycles.
