Заглавие : Reaction of 5-halo-1,2,3-thiadiazoles with aliphatic diamines. Synthesis and intramolecular cyclization of bis(1,2,3-triazolyl-1,2,3-thiadiazolyl)sulfides Место публикации : Organic and Biomolecular Chemistry. - 2003. - Vol. 1, № 22. - С. 4030-4038 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Bis[1,2,3]triazolo[1,5-f:5?,1?-b][1,3,6]thiadiazepine and [1,5-g:5?,1?-b][1,3,7]thiadiazocine ring systems have been synthesized from 5-halo-1,2,3-thiadiazoles and aliphatic diamines. We have found that the last step of the process is the cyclization of initially formed bis(1,2,3-triazolyl-1,2,3-thiadiazolyl)sulfides. The structures of the intermediates and products were supported by different NMR spectroscopic methods (1H coupled 13C NMR, 2D HETCOR, HMBC and 1D INADEQUATE experiments) and mass spectrometry. Differences in the reaction pathway for aliphatic and less nucleophilic aromatic diamines were determined.
