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

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.

Ключевые слова (''Своб.индексиров.''): 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: 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

Ключевые слова (''Своб.индексиров.''): chitosan--selectivity--sorption
Аннотация: This study presents a simple and effective synthesis method of N-(2-sulfoethyl)chitosan (NSE-chitosan) via a reaction between sodium 2-bromoethanesulfonate and chitosan that allows polymer transformation without using additional reagents and organic solvents. The chemical structure of the obtained NSE-chitosan was characterized by FT-IR and 1H NMR spectroscopies. Thermogravimetric study of NSE-chitosan coupled with FT-IR analysis has shown stability of the polymer up to 200 °C, which almost does not change with the increase of degree of substitution (DS). The sorption of transition and alkaline earth metal ions from multicomponent solutions on NSE-chitosan was investigated. The synthesized sorbents showed the selective recovery of silver(I) and copper(II) ions from ammonium acetate buffer solution. The increase of DS enhanced the selectivity to silver(I) ions sorption in comparison with copper(II) ions. Selectivity coefficients KAg/Cu increase from 1.3 to 10.9 with DS increasing up to 0.7 (ammonium acetate buffer solution, pH 6.5). Sorption isotherms of transition metal ions on NSE-chitosan with DS = 0.5 have been fitted using Langmuir, Freundlich, and Redlich-Peterson models. The maximum sorption capacities of sorbent in ammonium acetate buffer solution at pH 6.0 were 1.72 mmol/g for Cu(II), 1.23 mmol/g for Ag(I) and below 0.5 mmol/g for Co(II), Zn(II), Cd(II), Pb(II), Mn(II) and Ni(II) ions

Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Reactions of transesterification of dimethyl, diethyl and dibutyl carbonates with 2,2,3,3-tetrafluoroethyl-, 2,2,3,3,4,4,5,5-octafluorobutyl- and 2,2,3,3,4,4,5,5,6,6,7,7-dodecafluorohexyl-carbinols were investigated in the presence of various catalysts. It was found that the conversion of starting dialkyl carbonate increases upon increasing the length of fluorine-containing radical in the presence of sodium alkoxide. It was shown that the maximum conversion of dimethyl carbonate (90%) was achieved in its reaction with 2,2,3,3,4,4,5,5-octafluoropentan-1-ol upon using catalysts such as K2CO3, NaOH, and sodium alkoxide. To achieve similar values of the conversion, Ti(OEt)4 and Ti(OiPr)4 should be used in the cases of diethyl and dibutyl carbonates, respectively.

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.

Аннотация: The results of this study of the electrochemical transformation of 3-R-4-hydroxy-1,4-dihydro-7-X-1,2,4-triazolo[5,1-c][1,2,4] obtained by voltammetry are presented. It was found that 3-R-4-hydroxy-1,4-dihydro-7-X-1,2,4-triazolo[5,1-c][1,2,4] derivatives are capable of electrochemical reduction in the potential range of -0.28 to -0.33 V (relative to Ag/AgCl) in Britton-Robinson buffer at pH = 2. The electrochemical behavior of the sodium salt of 3-nitro-4-hydroxy-7-methylthio-4H-[1,2,4]triazolo[5,1-c][1,2,4]triazinide monohydrate (compound 1), which in silico modeling predicted possible biological activity against various tick-borne encephalitis and Coxsackie B3 viruses. At the potentials of the first stage of electroreduction at pH = 2, the main transformation process is the three-electron reduction scheme of the nitro group of compound 1. It was established that compound 1 in an aprotic medium is reduced in ionic form, most likely in the form of an ion pair with the Na+ cation, and in an aqueous medium in the form of a protonated particle. Based on this, a scheme was proposed for the probable electrochemical transformation of the studied compound.

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

Аннотация: 1,8-Bis(diisothiosemicarbazido)-3,6-dioxaoctane have been synthesized by subsequent treatment of 2,2 -(ethylenedioxy)bisethylamine with carbon disulfide, sodium chloroacetate, and hydrazine hydrate. 1,8-Bis- (diisothiosemicarbazido)-3,6-dioxaoctane has reacted with lithium 1,1-difluoropenta-2,4-dionate in glacial acetic acid to yield 1,8-bis[5R*,5 R*(5-hydroxy-5-difluoromethyl-4,5-dihydro-3-methyl-1H-pyrazol-1-yl)-1-carbothioamido]-3,6-dioxaoctane. The molecular and crystal structure of the product has been determined by X-ray diffraction analysis.
