Аннотация: Extensive research on the synthesis and application of tetrazine derivatives for electronic devices, luminescent elements, photoelectric conversion elements, and image sensors has been published recently. This review covers reported data on the modern trends in the design of functionalized tetrazines obtained within the period 2010–2020. Aryl(heteroaryl) and arylvinyl derivatives of tetrazines and their photoluminescence and application for fluorogenic probes are discussed. Examples of photosensitive oligomers and polymer 3,6-dithienyltetrazines are reviewed.

    1,3,7-triazapyrene-based ortho-carborane fluorophores: convenient synthesis, theoretical studies, and aggregation-induced emission properties / L. A. Smyshliaeva, M. V. Varaksin, E. I. Fomina [et al.] // Organometallics. - 2021. - Vol. 40, № 16. - P2792-2807
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A convenient transition-metal-free approach, based on nucleophilic substitution of hydrogen (SNH), for consecutive regioselective C–H functionalization of 1,3,7-triazapyrene scaffolds with carboranyllithium and phenyllithium is reported. The theoretical calculations disclosed highlight key features in the regioselectivity and mechanism of the investigated SNH transformations. The novel 1,3,7-triazapyrene-based ortho-carboranes obtained have large potential in the field of molecular electronics as organic luminophores, which are characterized by the aggregation-induced emission and dual-emission effects.

    15N chemical shifts and Jnn-couplings as diagnostic tools for determination of the azide-tetrazole equilibrium in tetrazoloazines / S. L. Deev, T. S. Shestakova, Z. O. Shenkarev [et al.] // Journal of Organic Chemistry. - 2022. - Vol. 87, № 1. - P211–222
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Selectively 15N-labeled tetrazolo[1,5-b][1,2,4]triazines and tetrazolo[1,5-a]pyrimidines bearing one, two, or three 15N labels were synthesized. The synthesized compounds were studied by 1H, 13C, and 15N NMR spectroscopy in DMSO and TFA solutions, where the azide–tetrazole equilibrium can lead to the formation of two tetrazole (T, T′) isomers and one azide (A) isomer for each compound. Incorporation of the 15N-label(s) leads to the appearance of 15N–15N coupling constants (JNN), which can be easily measured via simple 1D 15N NMR spectra, even at natural abundance between labeled and unlabeled 15N atoms. The chemical shifts for the 15N nuclei in the azole moiety are very sensitive to the ring opening and azide formation, thus providing information about the azido–tetrazole equilibrium. At the same time, the 1–2JNN couplings between 15N-labeled atoms in the azole and azine fragments unambiguously determine the fusion type between tetrazole and azine rings in the cyclic isomers T and T′. Thus, combined analysis of 15N chemical shifts and JNN values in selectively isotope-enriched compounds provides an effective diagnostic tool for direct structural determination of tetrazole isomers and azide form in solution. This method was found to be the most simple and efficient way to study the azido–tetrazole equilibrium.

1H NMR -- 13C NMR -- CONDENSED TETRAHYDROQUINOXALINES
Аннотация: The 1H and 13C NMR spectra of tetrahydroquinoxalines condensed with pyridazine, pyrazine, oxazine, oxadiazine, thiadiazine or triazine rings have been measured in DMSO-d6 solution. The effects of six-membered heterocycles on 1H and 13C chemical shifts and the values of one-bond 1J(CH) and vicinal 3J(HH) coupling constants for the ring junction fragment are considered. The differences between the 1H and 13C spectral parameters of tetrahydroquinoxalines annelated with five- or six-membered heterocycles with the same set of heteroatoms attached to the ring junction carbons are also discussed.
