Аннотация: The synthesis of hetrogenized vanadyl acetylacetoonate was accomplished by alkylation of a chloromethylated styrene-divinylbenzene copolymer via activation by Co (II) complexes. The effect of heterogenization of the structure of the complexes and their catelytic properties in the peroxide oxidation of anthracene was investigated by kinetic studies and ERP spectroscopy

Аннотация: Acidic hydrolysis of N-acyl 1-methyl- and 1-phenyl-3-amino-1,2-dicarba-closo-dodecaboranes has been studied. It has been shown that acidic hydrolysis of diastereomeric amides of 1-methyl-3-amino-1,2-dicarba-closo-dodecaborane results in the partial racemization of the target 3-amino-1-methylcarborane. Under the similar conditions, the hydrolysis of N-acyl-3-amino-1-phenyl-1,2-dicarba-closo-dodecaboranes resulted in amide bond cleavage accompanied by simultaneous deboronation with the removal of boron atom at position 6 of carborane cage and formation of 7,8-dicarba-nido-undecaborane derivative according to 11B and 1H NMR spectroscopy.

    Study of rare encounters in a membrane using quenching of cascade reaction between triplet and photochrome probes with nitroxide radicals [Text] / N. Medvedeva, V. Papper, G. I. Likhtenshtein // Physical Chemistry Chemical Physics. - 2005. - Vol. 7, № 18. - P3368-3374. - Библиогр. : с. 3373 (26 назв.)

Аннотация: Measurements of active encounters between molecules in native membranes containing ingredients, including proteins, are of prime importance. To estimate rare encounters in a high range of rate constants (rate coefficients) and distances between interacting molecules in membranes, a cascade of photochemical reactions for molecules diffusing in multilamellar liposomes was investigated. The sensitised cascade triplet cis-trans photoisomerisation of the excited stilbene involves the use of a triplet sensitiser (Erythrosin B), a photochrome stilbene-derivative probe (4-dimethylamino-4 -aminostilbene) exhibiting the phenomenon of trans-cis photoisomerisation, and nitroxide radicals (5-doxyl stearic acid) to quench the excited triplet state of the sensitiser. Measurement of the phosphorescence lifetime of Erythrosin B and the fluorescence enhancement of the stilbene-derivative photochrome probe, at various concentrations of the nitroxide probe, made it possible to calculate the quenching rate constant kq= 1.1*10 15 cm2 M-1 s-1 and the rate constant of the triplet-triplet energy transfer between the sensitiser and stilbene probe kT= 1.0*1012 cm2 M-1 s-1. These values, together with the data on diffusion rate constant, obtained by methods utilising various theoretical characteristic times of about seven orders of magnitude and the experimental rate constants of about five orders of magnitude, were found to be in good agreement with the advanced theory of diffusion-controlled reactions in two dimensions. Because the characteristic time of the proposed cascade method is relatively large (0.1 s), it is possible to follow rare collisions between molecules and free radicals in model and biological membranes with a very sensitive fluorescence spectroscopy technique, using a relatively low concentration of probes.

    Structure and properties of 4-amino derivatives of 5-oxoproline [Text] / V. P. Krasnov, I. A. Nizova, A. Yu. Vigorov, T. V. Matveeva, G. L. Levit, P. A. Slepukhin, M. A. Ezhikova, M. I. Kodess // European Journal of Organic Chemistry. - 2008. - № 10. - P1802-1810

Аннотация: On the basis of the results obtained from NMR spectroscopy, X-ray analysis and chemical transformations, it was established that acidic hydrolysis of (2S,4S)-4-arylaminoglutamates results in the formation of lactams in which ring closure occurs with the participation of the Y-amino and alfa-COOH groups; but isomeric lactams resulting from the participation of the alfa-amino and Y-COOH groups are not formed. Isomeric lactams, that is, (2S,4S)-4-arylamino-5-oxoprolines, can be easily converted in acidic medium into more stable 4-amino-1-aryl-5-oxoprolines.

    Syntheses of novel 4-polyfluoroalkyl-substituted 5,6-oligomethylene pyrimidines [Text] / D. V. Sevenard, O. G. Khomutov, O. V. Koryakova, V. V. Sattarova, M. I. Kodess, J. Stelten, I. Loop, E. Lork, K. I. Pashkevich, G. -V. Roeschenthaler // Synthesis. - 2000. - № 12. - P1738-1748

Аннотация: 2-Acylcycloalkanones having polyfluoroalkyl groups react with guanidine, urea, thiourea, methylisothiourea, benzamidine, guanylthiourea, dicyanodiamide, and trifluoroacetylurea by Lewis-acid catalysis to form the corresponding 5,6-oligomethylene pyrimidines. A decrease in the yields along with increase of polyflyoroalkyl substituent length in the molecule of the starting 1,3-diketone was observed in the case of reagents with lower nucleophilicity (urea, thiourea, dicyanodiamide). The pyrimidines obtained from aromatic aldehydes showed E-configuration with respect to the arylidene double bond. Tautomeric structures as a function of the substituent in 2 position in the pyrimidine ring both in liquid and solid state were investigated by X-ray diffraction, IR and NMR spectroscopy.

Аннотация: Radical species generated from 5-aryl-substituted 1-ethyl-2,3-dicyano-1,4-diazinium salts by action of sodium iodide undergo dimerization into [2,2?]bipyrazinyl derivatives, as evidenced by NMR and X-ray crystallography data. The pyrazinyl radicals can also be involved into the addition reaction on the C-C triple bond, thus demonstrating a new synthetic route to modify the structure of pyrazines. The structures of E- and Z-isomers of 1-(1?,2?-dihydropyrazinyl-2?)-2-iodoethenes have been proved by 1H and 13C NMR spectroscopy and X-ray analysis
