This thesis describes the synthesis of a novel pyridinium salt bearing triazolylidene fragment bounded to pyridine nitrogen atom, which has not yet been described in the literature. The synthesized salt represents a potential bidentate dicarbene NHC ligand, useful for the formation of transition metal NHC complexes. The synthesis was performed in six steps, where the starting alkyne, 1-ethynyl-4-phenylpyridin-1-trifluoromethanesulfonate, and benzyl azide, were independently prepared according to the literature reports. Following, a Cu(PPh3)3Br catalyzed click reaction between the desired alkyne and azide was performed to give the corresponding triazole, 1- (1-benzyl-1H-1,2,3-triazol-4-yl) -4-phenylpyridin-1-yl trifluoromethanesulfonate. In the last step, the triazole was methylated at the N3 position to give the final product, 1- (1-benzyl-3-methyl-1H-1,2,3-triazol-3-yl-4-yl) -4-phenylpyridin- 1-trifluoromethanesulfonate. Unfortunately, the final product was not purified, due to its decomposition on a SiO2 column.
