The chemistry of heterocyclic compounds has traditionally been and remains a bright area chemical science in Russia. This is due to the fact that many heterocycles find widest application. These are key structural fragments most drugs, plant protection agents. Many natural also derivatives heterocycles. At present, more than half hundreds millions known collective review devoted achievements Russian chemists this field over last 15–20 years. presents leading heterocyclists representing both RAS institutes university science. It worth noting wide scope review, terms geography author teams, covering whole our large country, diversity research areas. Practically all major types represented review. special attention focused on practical applications design new drugs biologically active compounds, high-energy molecules, materials for organic electronics photovoltaics, ligands coordination chemistry, other rapidly developing advances would not be possible without development fundamental transformations chemistry.<br> Bibliography — 2237 references.

The stereochemistry of tautomeric functionalized azoles is a challenge for theoretical research, since the correct interpretation chemical behaviour and biological activity these compounds depends on understanding factors that determine structural features relative stability their tautomers. Due to physicochemical properties, 1,2,3- 1,2,4-triazoles are most promising research objects in various fields ranging from medicine, bioorganic chemistry agrochemistry materials science. This review first in-depth analysis data structure stereochemical 1,2,3-triazoles (their carbaldehydes, carbaldehydoximes, barbiturates malononitriles), model analogues, as well related compounds, obtained by combined methods based multipulse multinuclear 1H, 13C, 15N 29Si NMR spectroscopy quantum calculations. <br> bibliography includes 320 references.

Modification of 5-aryl-4-trifluoroacetyltriazoles at the NH-moiety was investigated. Screening alkylation conditions revealed that using Na2CO3 as a base and DMF solvent 2-substituted triazoles can be preferentially prepared in up to 86% yield. In best cases, amount minor 1-alkyl isomer less than 6%. SNAr reaction with aryl halides having electron-withdrawing groups led regiospecific formation 2-aryltriazoles isolated good-to-high yields. Chan-Lam boronic acids afforded single isomers 89% The subsequent primary secondary amines gave set amides 4-(2,5-diaryltriazolyl)carboxylic acid. fluorescent properties derivatives were investigated demonstrate their utility new efficient luminophores more 60% quantum

The exchange coupling, represented by the J parameter, is of tremendous importance in understanding reactivity and magnetic behavior open-shell molecular systems. In past, it was subject theoretical investigations, but these studies are mostly limited to interaction between metallic centers. coupling paramagnetic metal ions radical ligands has hitherto received scant attention studies, thus factors governing this lacking. paper, we use DFT, CASSCF, CASSCF/NEVPT2, DDCI3 methods provide insight into semiquinonato copper(II) complexes. Our primary objective identify structural features that affect interaction. We demonstrate character Cu(II)-semiquinone complexes mainly determined relative position semiquinone ligand Cu(II) ion. results can support experimental interpretation data for similar systems be used in-silico design with ligands.
