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.
