Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): AZIDO-TETRAZOLE EQUILIBRIUM -- SPIN-SPIN COUPLING -- 2-AZIDOPYRIMIDINES Аннотация: A new method was developed for the investigation of an azido-tetrazole equilibrium based on using a complex analysis of 13C-15N and 1H-15N spin-spin coupling constants. The use of this approach became possible due to the selective inclusion of 15N isotopes into the structures of 2-azidopyrimidines and their cyclic analogs tetrazolo[1,5-a]pyrimidines \\\\expert2\\nbo\\Russian Chemical Bulletin\\2013, 62 (2), 521-528.pdf |
