The cycloaddition of HN3 to accessible α-nitrostilbenes affords new 4,5-diaryl-1,2,3-triazoles in high yields (70–91%). This method is characterized by the simplicity and the ease of isolation of the final products and does not require the use of an inert atmosphere and/or metal catalysts. Under basic conditions, the alkylation proceeds with high regioselectivity at the endocyclic N(2) atom. The crystal and molecular structure of 4-(4-methoxy-3-nitrophenyl)-2-methyl-5-phenyl-1,2,3-triazole was established by X-ray diffraction analysis. The hydrogenation of the nitro group using the Zn—AcOH—NH4Br system gives the corresponding aminoaryl-substituted triazoles in high yields.
