    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.

Аннотация: A new synthetic approach to condensed 1,2,4-triazines based on using the tandem AN-SNipso and SNH-SNipso reactions has been developed. 5-Methoxy-3-penyl-l,2,4 1,2,4-triazine and its N1-methyl quaternary salt were found to react with C,N-, C,O- and N,N?-bifunctional nucleophiles (m-phenylenediamine, resorcinol, semicarbazide and ureas) into triazacarbazoles, benzofuro[2,3-e][1,2,4]-triazines, and 6-azapurine derivatives. In all cases nucleophiles attack first the unsubstituted C-6 carbon of the triazine ring, while the final stage is replacement of the methoxy group affording cyclization products.

Аннотация: In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2, as an effective photocatalytic oxidative system. It has been shown that this versatile approach can be applied for direct C-H functionalisation of a variety of azaaromatic systems, such as mono-, di- and triazines, substituted and unsubstituted azines and their benzo-annelated analogues.

1,2,4-TRIAZINES -- NITROGEN-CONTAINING HETEROCYCLES
Аннотация: Among the six-membered nitrogen-containing heterocycles the 1,2,4-triazines have attracted the attention of chemists for a long time. This is due to the fact that many 1,2,4-triazine derivatives are biologically active and are used in medicine and agriculture. Moreover, 1,2,4-triazines are of chemical interest. They proved to be very susceptible to attack by all kinds of nucleophiles, leading to the addition, and subsequently either substitution or cyclization, and ring transformation. This continuing and lively interest in this area of heterocyclic chemistry has produced a great number of publications and patent applications. This chapter concentrates on the behavior of monocyclic 1,2,4-triazines in reactions with C-, N-, 0-, and S-nucleophiles, because the important features of general character established for simple 1,2,4-triazines can evidently be applied to other derivatives including condensed 1,2,4-triazines.

NITROAROMATIC EXPLOSIVES -- FLUORESCENCE QUENCHING -- PYRIDINES -- PYRAZINE -- PYRIMIDINES -- TRIAZINES
Аннотация: Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azaheterocyclic scaffold, their functionality and their ability to detect of nitroaromatics by fluorescence quenching.
