Abstract

ABSTRACT This review mainly focuses on purely Ag-catalyzed 1,3-dipolar azide-alkyne cycloaddition (AgAAC) so called click reaction to synthesize 1,4-regioisomers of 1,2,3-triazoles. The most established catalyst Cu (I) developed by Fokin–Sharpless and Meldal group in 2002 for AAC reaction have been further extended to different other transition metal catalysts because of certain limitations of CuAAC methods. Among different transition metal catalyzed methods, AgAAC is the most studied one having same electronic configuration, d10 (AgI) with that of CuI and shows high catalytic performance.
银催化叠氮化物-炔环加成:无铜合成1,4-二取代1,2,3-三唑的方法
摘要本文主要综述了纯银催化的1,3-偶极叠氮-炔环加成反应(AgAAC)合成1,2,3-三唑的1,4-区域异构体。2002年由Fokin-Sharpless和Meldal小组开发的用于AAC反应的最成熟的催化剂Cu (I),由于CuAAC方法的某些局限性,进一步扩展到其他不同的过渡金属催化剂。在不同的过渡金属催化方法中,AgAAC是研究最多的一种,其电子构型与CuI相同,d10 (AgI),具有较高的催化性能。
