Аннотация: 5(6)-Fluoro-6(5)-substituted benzofuroxans were obtained by the reactions of 5,6-difluorobenzofuroxan with a number of nucleophiles, such as alkylamines, cycloalkylimines, sodium azide and sodium alkoxides. The features of tautomerism in the series of asymmetrical 5(6)-fluorobenzofuroxans in acetone solutions have been studied by 1H, 13C and 19F NMR.????

Аннотация: We studied different approaches to the synthesis of polyfluoroalkyl-containing 1-methyl-4-nitrosopyrazoles, which are based on the cyclization of 4,4,4-trifluoro-3,3-dihydroxy-2-hydroxyimino-1-R-butan-1-ones or 2-hydroxyimino-1,3-diketones with methylhydrazine and on a one-pot sequential treatment of 1,3-diketones with sodium nitrite and methylhydrazine. It was found that the regioselectivity of the formation of 1-methyl-4-nitrosopyrazoles is affected by the steric factors of 1,3-dicarbonyl reagents. The study of the mycostatic effect of 4-nitrosopyrazoles showed that the introduction of a bulky polyfluoroalkyl or tert-butyl substituent leads to a decrease in their activity.

Ключевые слова (''Своб.индексиров.''): sol-gel method--zirconium oxychloride--silica-zirconia xerogels
Аннотация: The composite silica-zirconia xerogels have been prepared via sol-gel method using zirconium oxychloride, oxynitrate, acetate and sodium silicate as the precursors. The prepared materials have been characterized using FTIR, TG/DTA, EDX and surface area analyses. It has been established that surface area of silica-zirconia xerogels significantly depends on the zirconium source, but phase transitions and structural features of the xerogels seem to be unaffected by the choice of the zirconia precursor. Prepared xerogels increase the activity of chiral inductor in the asymmetric Biginelli reaction. The anion of the zirconium salt adsorbed on the surface of the synthesized material and the presence of Si-O-Zr heterolinkages determines the reaction yield. The highest chemo- and enantioselectivity towards formation of ee isomer have been provided by the catalyst prepared from zirconium oxychloride.

Аннотация: It was established with the use of electron and ESR spectroscopic methods that in the presence of sodium sulfate, the extraction of vanadium (IV) with di-2-ethylhexylphosphoric acid takes place by a cation-exchange mechanism giving rise to two complex compounds of vanadium (IV) oxocation with sulfuric and di-2-ethylhexylphosphoric acid anions. The vanadium (IV) oxocation sulfate complex extracted in the solid state was examined with X-ray structural analysis. It was shown that the vanadium (IV) oxocation sulfate complex trihydrate crystallizes in the centrosymmetrical space group to form dimers with bridging sulfate groups

Аннотация: Study of the Khitoostrov, Varatsk, and other corundum occurrences in kyanite-garnet-biotite plagiogneisses of the Chupa section (Belomorian Mobile Belt) has revealed their association with products of low-alkaline Ca-Na metasomatism characterized by high PT conditions. Similar corundum-bearing rocks, which were also presumably formed during subalkaline metasomatism, are known in Tanzania, India, the United States, and other countries. This paper presents the first results of analysis of the corundum-forming Ca-Na metasomatism.

Аннотация: Two methods for synthesis of new nucleosides bearing 6-phenyl-1,2,4-triazolo[1,5-a]pyrimidin-7-ones as a base have been developed. The first one includes Vorbruggen glycosylation reaction. The second method, which is effective for synthesis of acyclic nucleosides, is based on the condensation between sodium salts of 6-phenyl-1,2,4-triazolo [1,5-a]pyrimidin-7-ones and 4-bromobuthyl acetate or (Z)-4-bromobut-2-en-1-yl acetate ??

Аннотация: New organic-inorganic materials based on products of interaction between sodium aminoprusside and polymer ligand (chitosan) have been synthesized. The composition of the obtained materials was characterized using the element analysis and X-ray diffraction; the Fourier transform infrared (FT-IR) spectroscopy and Thermogravimetric analysis data were used to propose the structure of the formed complexes. It was established that ion and ligand exchange were the main reactions at interaction of sodium aminoprusside with water-soluble chitosan salts. The comparative estimation of the sorption capacity with respect to cesium ions was performed for the synthesized complexes. It has been shown that the complex of chitosan with pentacyanoferrate(II) in the form of cobalt(II) salt has higher distribution coefficient with respect to Cs+ ions, as compared to cobalt aminoprusside. The maximum sorption capacity value for Cs+ was evaluated from the sorption isotherm and found to be equal to 0.3 mmol/g

Ключевые слова (''Своб.индексиров.''): sodium aminoprusside --polymer ligands (chitosan)--polyallylamine
Аннотация: Here we report on synthesis of new organic–inorganic materials based on products of interaction between sodium aminoprusside and polymer ligands (chitosan (CS), N-2-(2-pyridyl)ethylchitosan (2-PC), N-2-(4-pyridyl)ethylchitosan (4-PC), N-(4-methyl-5-imidazolyl)methylchitosan (IC), N-(2-cyanoethyl)chitosan (CC), polyallylamine (PA), N-(2-pyridyl)methyl-polyallylamine (PMPA), N-2-(2-pyridyl)ethyl-polyallylamine (PEPA), N-(4-methyl-5-imidazolyl)methyl-polyallylamine (IPA) and poly(2-vinylpyridine) (PVP)). The composition of the obtained materials was characterized using the element analysis and X-ray diffraction; the Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis data were used to propose the structure of the formed complexes. It was established that ion and ligand exchange were the main reactions, through which sodium aminoprusside interacts with water-soluble polymer salts. Reactivity in complex formation reaction of unmodified polymers changes in a row: PA CS PVP. Modification of chitosan with 2-(4-pyridyl)ethyl and 2-cyanoethyl moieties enhances reactivity of chitosan to the level of PA, while introduction of 2-(2-pyridyl) and (4-methyl-5-imidazolyl)methyl moieties, on the contrary, decreases reactivity of chitosan to that of PVP. At the same time, functionalization of PA with 2-pyridylalkyl groups decreases its reactivity in reaction with aminoprusside ion. Thus, reactivity of all studied polymeric matrices changes in the row: PA ≈ 4-PC ≈ CC CS 2-PC ≈ IPA ≈ IC PMPA PVP PEPA. The distribution coefficients with respect to cesium ions have been determined for the synthesized complexes in cobalt(II) form. It has been shown that the complex of chitosan with pentacyanoferrate(II) has higher distribution coefficient with respect to Cs+ ions, as compared to its N-derivatives and synthetic polymers. Organic–inorganic materials obtained in the matrix of synthetic polymers have shown higher tendency to peptization and, therefore, lower sorption capacities and distribution coefficients
