摘要：

An interesting approach for synthesis of disubstituted-1,2,3-(NH) triazoles from easily available raw materials and reagents like substituted acetophenones, iodine, DMSO and NaN3 via intermolecular 1,3-dipolar cycloaddition reaction. Trisubstituted triazoles and its corresponding triazolo pyridazine could be made easily using this method. These are key intermediates for poly benzodithiophene triazole (PBnDT-TAZ) for solar cells and 1-benzyl-1H-4,5-dibenzoyl-1,2,3-triazole (BDBT) for corrosion inhibition.
