Abstract

V magistrskem delu je opisana sinteza treh različno substituiranih triazolijevih soli. Izhajali smo iz terminalnega alkina in organskega azida, iz katerih smo z azid-alkin cikloadicijo, katalizirano z bakrom(I), sintetizirali triazol in iz njega v nadaljevanju analogno triazolijevo sol. Sintetizirani sta bili 5-metil-3-fenil-4-(piridin-2-il)-1-(p-tolil)-1H-1,2,3-triazol-3-ijev trifluorometansulfonat in 5-etil-3-fenil-4-(piridin-2-il)-1-(p-tolil)-1H-1,2,3-triazol-3-ijev trifluorometansulfonat, medtem ko sinteza 4-((difenilfosfanil)metil)-5-metiltriazolijeve soli ni bila uspešna. Namesto zadnje smo izolirali na fosfinski ročici metiliran produkt.

Secondary title: Synthesis of selected triazolium salts as precursors for mesoionic N-heterocyclic olefins
Secondary abstract: 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.
