MICROWAVE IRRADIATION -- AMINOPYRAZOLES -- ARYLSULFANYL(DIFLUORO)METHYL GROUP
Аннотация: Methods for the synthesis of 4 R 6,7 dihydro 1H pyrazolo[3,4 b]pyridin 6 ones (R = CF2SAr and 4 CFHSAr) were developed. The derivatives with R = CF2SAr were ob tained by both heterocyclization of 1 substituted 5 aminopyrazoles with ethyl 4,4 difluoro 3 oxo 4 phenylsulfanylbutanoate and replacement of the Br atom in 4 bromodifluoromethyl 6,7 dihydro 1H pyrazolo[3,4 b]pyridin 6 ones by sodium arenethiolates. The fragment 4 CF HSAr was introduced by replacement of the Cl atom in 4 chlorofluoromethyl 6,7 dihydro 1H pyrazolo[3,4 b]pyridin 6 ones by sodium arenethiolates. Oxidation of 4 CF2SPh 6,7 dihydro 1H pyrazolo[3,4 b]pyridin 6 ones gave the corresponding sulfoxides; their structures were con firmed by X ray diffraction data

THERMODYNAMIC MODELING -- SODIUM METHOXIDE -- POLYCHLORINATED BIPHENYLS
Аннотация: Thermochemical parameters, like standard enthalpy of formation (ΔH 298 0), enthalpy increment from 0 to 298 K (H 298 0 - H 0 0), standard heat capacity (C p298 0) and its temperature dependence [Cp(T)], and entropy (S 298 0), were calculated for the gaseous methoxy derivatives formed from polychlotinated biphenyl (PCB) congeners. Thermodynamic modeling and the HSC software were used to evaluate the reactivity of PCB congeners toward sodium methoxide in DMSO, and the calculation results were compared with experimental data

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.

SODIUM AMINOPRUSSIDE -- POLYMER LIGAND (CHITOSAN) -- X-RAY DIFFRACTION
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

Аннотация: 1,2-Bis(azidomethyl)-о-carborane and 1,7-bis(azidomethyl)-m-carborane, prepared from the corresponding carboranylmethyl triflates and sodium azide, were conveniently functionalized by azide–alkyne cycloaddition affording novel bis[(1,2,3-triazolyl)methyl]carborane derivatives. Regiospecificity of this process was achieved by employing copper(II) acetate hydrate. Reaction of bis[(1,2,3-triazolyl)methyl]carborane derivatives with MeI yielded 3-methyl-1,2,3-triazolium carborane salts

The interaction of the congeners with sodium methoxide was performed and their complete conversion was proved. By means of gas chromatography-mass spectrometry the PCBs methoxy derivatives were identified. The data on the reactivity of the individual polychlorobiphenyl congeners were precised

ELECTRONIC SPECTRA -- ESR SPECTROSCOPY -- VANADIUM
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: Oxidation of cyclohexanone to ɛ-caprolactone with stable industrially manufactured hydrogen peroxide derivatives: adduct with urea (urea hydrogen peroxide), sodium perborate, sodium percarbonate (Persol), magnesium monoperphthalate (Dismozon) was studied. Oxidation with urea hydrogen peroxide is the most efficient in hexafluoroisopropanol in the case of preliminary removal of urea in the form of an oxalate. Oxidation with sodium perborate and percarbonate provides high yields in trifluoroacetic acid. The lowest cost process consists in interaction with sodium monoperphthalate (Persol and phthalic anhydride) in an aqueous medium
