In my masters' thesis, I describe the synthesis of three differently substituted triazolium salts. We started the synthesis from a terminal alkyne and an organic azide, from which we synthesised a triazole through copper(I)-catalyzed azide-alkyne cycloaddition, and subsequently an analogous triazolium salt. The 5-methyl-3-phenyl-4-(pyridin-2-yl)-1-(p-tolyl)-1H-1,2,3-triazol-3-ium trifluoromethanesulfonate and 5-ethyl-3-phenyl-4-(pyridin-2-yl)-1-(p-tolyl)-1H-1,2,3-triazol-3-ium trifluoromethanesulfonate were synthesised, while the synthesis of 4-((diphenylphosphanyl)methyl)-5-methyltriazolium salt was not successful. Instead of the latter, we isolated the methylated product on the phosphine arm.
