Аннотация: The scope of functionalization of 1,2,4-triazines can be considerably extended via successive nucleophilic substitution of hydrogen (SN H) and ipso-substitution. A convenient procedure has been developed for direct cyanation of 1,2,4-triazine 4-oxides with acetone cyanohydrin in the presence of triethylamine. The cyano group in the resulting 5-cyano-1,2,4-triazines is readily replaced by reactions with various aliphatic alcohols and amines

Заглавие : The structure of 4-phenyl-2,6-bis(trifluoroacetyl)cyclohexanone and its dilithium salt in the crystal state, solution and gas phase

Аннотация: 4-Phenyl-2,6-bis(trifluoroacetyl)cyclohexanone and its dilithium salt were synthesized starting from the commercially available 4-phenylcyclohexanone. With X-ray structure analysis of these compounds, for the first time the solid state structure determination for a fluorinated 1,3,5-triketone and an alkaline salt of 1,3,5-triketone was achieved. The subsequent multinuclear NMR and MS investigations revealed that in solution and gas phase, analogously to the crystal, both compounds exist predominantly in a highly delocalized double U-enol(ate) form. The carbonyl O…O distances in the dilithium salt were established to be considerably longer than the distances between oxygens of the parent 1,3,5-triketone, bonded by strong (short) resonance assisted hydrogen bonds. Among the 1,3,5-tricarbonyl compounds with known crystal structure, the entitled 1,3,5-triketone shows comparatively weak delocalization over the conjugated bis-enolone backbone.

Заглавие : The epithermal gold-telluride Kochbulak deposit (Uzbekistan)

Аннотация: The Paleozoic epithermal gold-telluride Kochbulak deposit is situated on the northern slope of the Kurama Range in the central Tien Shan (Uzbekistan). The deposit is located within an andesite-dacite volcanic sequence (C2-3) intruded by subalkaline granodiorite and granosyenite porphyry dikes (C3-P1). The ore-forming system of the deposit originated and evolved during the orogenic uplift associated with aerial volcanism and emplacement of porphyritic granitoids. The Kochbulak deposit contains a great diversity of ore-forming sulfides, sulphosalts, tellurides, and selenides, several of which were first found there. The deposit has features of epithermal mineralization of both the adularia-sericite and acid-sulfate genetic types and mesothermal gold mineralization. The deposit consists of high- and low-angle veins and ore-bearing breccia pipes. The pipe-shaped bodies and veins differ in ore, gangue, and metasomatic mineral assemblages. The ore bodies hosted by explosive-hydrothermal breccias contain goldfieldite, famatinite, luzonite, enargite, diaspore, and pyrophyllite and, therefore, have pronounced features of epithermal mineralization of the acid-sulfate type. The ore veins show evidence of deeper formation and are associated with quartz-carbonate-sericite wall rock alteration. Our study of mineral assemblages, fluid inclusions, sulfur, oxygen, and hydrogen isotopes, and thermodynamic calculations show that the Kochbulak deposit was formed during a cyclic multistage process with periodic alternation of sealing along with tectonic and explosive opening of the fluid channel ways. The ore-forming process is subdivided into the preore, I to III ore, and postore stages related to fracture opening. Three types of solutions took part in the formation of gold-sulfide-sulphosalt-telluride mineralization. They were distinct in temperature, composition, salinity, and proportion of meteoric and magmatic water and other volatile components. The temperature generally decreased from 465°C to 100°C, and slightly increased at the beginning of each stage of the ore-forming process. Pressure, salinity, ion and gas composition of solutions, and the oxygen isotope composition of water varied as well. The deposition of gold-productive mineral assemblages was caused by changes in pH, Eh, activities of S2, O2, and Te2. The recurrence of these changes and repeated mineral deposition within the same depth intervals formed bodies very rich in ore components. The above-mentioned data suggest the Kochbulak deposit represents a particular type of gold-telluride mineralization, which originated within a wide range of physicochemical conditions at hypabyssal to subsurface depths.????

Ключевые слова (''Своб.индексиров.''): organic dyes --pyrimidine--microwave-assisted
Аннотация: Six novel donor–π–acceptor organic dyes bearing a pyrimidine as the anchoring group have been obtained in good yields by combination of the microwave-assisted Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen reactions. Their absorption, photoluminescence and electrochemical properties were fully investigated in detail. The infrared spectra of dyes adsorbed on TiO2 indicate the formation of coordinate bonds between the pyrimidine ring of dyes and the Lewis acid sites (exposed Tin+ cations) of the TiO2 surface. This work demonstrates that the pyrimidine rings of dye sensitizers that form a coordinate bond with the Lewis acid site of a TiO2 surface are promising candidates as the electron-withdrawing anchoring group. The data from quantum calculations show that all of the dyes are potentially good photosensitizers for dye-sensitized solar cells

Ключевые слова (''Своб.индексиров.''): pyrimidines--carbazole--dye-sensitized solar cells
Аннотация: Novel donor-pi-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

Ключевые слова (''Своб.индексиров.''): benzimidazoles--antifungal activity--tubulin--carbendazim
Аннотация: This work deals with the synthesis and evaluation of fungicidal activity of benzimidazole derivatives, which are structural analogues of commercial anti-tubulin fungicides. A number of N-acyl and N-thioacyl derivatives of 2-amino-1H-benzo[d]imidazole were prepared, and their fungicidal activity against 13 strains of phytopathogenic fungi was studied. The most active compounds against the majority of the studied strains were 3a, 4l, and 4o, and the EC50 values of these compounds were in the range 2.5–20 μg/mL. Compound 3a showed the highest activity against the P. infestans strain, the growth of which is not suppressed by carbendazim. The formation of ligand–receptor complexes of various tautomeric forms of the studied benzimidazoles with homologous models of β-tubulins of B. cinerea, F. oxysporum, and P. infestans was modeled. Induced fit docking has been used for the simulation. The obtained data suggest the possibility of binding of benzimidazole fungicides to β-tubulin in the ″nocodazole cavity″ in the tautomeric form bearing a double exocyclic C═N bond. The importance of the formation of hydrogen bonds of benzimidazoles with the amino acid residue Val236 along with the Glu198 residue is also revealed in the present study.

Аннотация: The efficiencies of hydrogen peroxide derivatives in the Baeyer–Villiger oxidation of cyclopen­tanone to δ-valerolactone have been compared. The oxidants used were hydrogen peroxide in acetic, formic, or trifluoroacetic acid, magnesium and sodium monoperoxyphthalates, cumene hydroperoxide, and tert-butyl hydroperoxide. The oxidation was carried out in water, aqueous methanol, and water–ethyl acetate. Sodium and magnesium monoperoxyphthalates turned out to provide high conversion and selectivity under mild conditions.

Аннотация: The reactions of 3-fluoro-4-R-6-phenylsulfonylmethylnitrobenzenes with dimethyl fumarate or diethyl maleate in acetonitrile in the presence of an excess of K2CO3 and a catalytic amount of 18-crown-6 afforded mixtures of dialkyl 6-R-7-fluoro- and dialkyl 6-R-7-phenylsulfonylquinoline-2,3-carboxylate N-oxides, as well as dialkyl 6-R-7-fiuoro- quinoline-2,3-carboxylates (alkyl is methyl or ethyl), which were resolved by column chromatography and identified by 1H NMR spectroscopy and X-ray diffraction
