摘要：

A one-pot, efficient, and straightforward procedure for the copper-catalyzed synthesis of 1,4-disubstituted 1,2,3-triazoles is studied by in situ generation of aryl azides via the reaction of aryldiazonium silica sulfates and sodium azide, followed by coupling with a terminal alkyne. These reactions are carried out in water at room temperature without using any additional ligands. (C) 2012 Elsevier Ltd. All rights reserved.
