Abstract

The synthesis of 1-monosubstituted 1,2,3-triazoles was achieved using azides and propiolic acid by copper-catalyzed click cycloaddition/decarboxylation, which was easily carried out in N,N-dimethylformamide at room temperature or 60 ˚C with yields ranging from moderate to excellent. The reaction conditions were found to be successful for aryl and vinyl azide reactants, including analogues with various functionalities.
