The embodiments provide for region-selective synthesis of tri-substituted 1,2,3-traizoles. A first embodiment provides for the selective N-2 alkylation of a 4,5-disubstituted 1,2,3-triazole. A second embodiment provides for the selective acetylation of a 4,5-disubstituted 1,2,3-triazole. A third embodiment provides for the selective arylation of a 4,5-disubstituted 1,2,3-triazole.
