Abstract

Abstract The synthesis of 1-monosubstituted aryl 1, 2, 3-triazoles was achieved using calcium carbide as a source of acetylene. The copper-catalyzed 1, 3-dipolar cycloaddition reactions were carried out without nitrogen protection and in a MeCN-H 2 O mixture. The yields ranged from moderate to excellent. The reaction conditions were found to be successful for aryl azide reactants, including analogues with various functionalities.
