The reactivity of 2-benzyl-1,2,3-triazole in palladium-catalyzed direct arylation was studied. The reaction conditions for the selective synthesis of 2-benzyl-4-aryl-1,2,3-triazoles in moderate to high yields using phosphine-free Pd(OAc)2 catalyst and inexpensive KOAc base have been found. Then, from these 4-aryl-1,2,3-triazoles, the palladium-catalyzed C?H bond functionalization of the C5-position allowed the synthesis of the corresponding 4,5-diarylated 2-benzyl-1,2,3-triazoles. This selective 4,5-diarylation of 2-benzyl-1,2,3-triazole was successfully applied for the straightforward building of the π-extended polycyclic heteroaromatic structures phenanthro[9,10-d][1,2,3]triazoles through Pd-catalyzed C4- and C5-intermolecular arylations followed by Pd-catalyzed C?H intramolecular arylation.

Four different series of triazole diamidines have been prepared by the Pinner method from the corresponding triazole dinitriles. Copper-catalyzed "click chemistry" was used for the synthesis of 1,4- and 4,5-substituted triazoles, aryl magnesium acetylide
