Аннотация: A procedure was developed for modification of titanium dioxide xerogel by addition of powder cellulose in the stage preceding hydrolysis of tetramethoxytitanium. The resulting catalytic systems based on the new material were studied in a model liquid-phase catalytic process of oxidative dehydrogenation of trimethylhydroquinone with atmospheric oxygen.

Ol'shevskaya, V. N. Kalinin, V. P. Krasnov, V. N. Charushin // Journal of Organometallic Chemistry. - 2005. - Vol. 690, № 11. - P2783-2786

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.

    The effect of mustard gas on the biological activity of soil [Text] / N. Medvedeva, Yu. Polyak, I. Kuzikova, O. Orlova, G. Zharikov // Environmental Research. - 2008. - Vol. 106, № 3. - P289-295
ББК 54

Аннотация: A special group of substances that are very dangerous for the biosphere includes war gases such as mustard gas (bis(2-chloroethyl)sulphide). The influence of mustard gas hydrolysis products (MGHPs) on soil microbiota has been investigated. These substances bear numerous toxic effects on soil microorganisms. They change significantly the number and the specific composition of soil microbiota and inhibit the enzyme activity of soils. The main "ecological targets" of mustard and its hydrolysis products' toxic action have been determined. MGHPs affect the growth and reproduction of soil micromycetes, as well as their morphological and cultural properties. Increase in number and size of mitochondria in the fungal cells is accompanied by increase in dehydrogenases activity. Cell permeability influenced by MGHPs grows in connection with concentration of toxicants. Increase of permeability corresponds to growth of the amount of unsaturated fatty acids. The changes in the fatty acid composition of lipids in the cells of the soil micromycetes display their adaptation to adverse impact of the substances studied. MGHPs and thiodiglycol enhance synthesis of polysaccharides and pigments.

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.

    Synthesis of fluorine-containing 2-(1-aryl-4-oxo-1,4-dihydrocinnolin-3-yl)-2-oxoacetic acids [Electronic resource] / A. S. Fokin, Ya. V. Burgart, V. I. Saloutin, O. N. Chupakhin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2005. - Vol. 41, № 9. - P1374-1376. - Библиогр. : с. 1376 (9 назв.)

Аннотация: Acid hydrolysis of ethyl 2-(1-aryl-5,6,7,8-tetrafluoro-4-oxo-1,4-dihydrocinnolin-3-yl)-2-oxoacetates gives 2-(1-aryl-5,6,7,8-tetrafluoro-4-oxo-1,4-dihydrocinnolin-3-yl)-2,2-dihydroxyacetic acids which undergo dehydration on heating in toluene to afford 2-(1-aryl-5,6,7,8-tetrafluoro-4-oxo-1,4-dihydrocinnolin-3-yl)-2-oxoacetic acids. Reactions of the latter with excess morpholine result in replacement of two fluorine atoms in positions 5 and 7 by the amine residues.

    (E)-1,1,1-trifluoro-4-phenyl-but-2-ene-4-one and trimethyl phosphite [Text] / V. G. Ratner, E. Lork, K. I. Pashkevich, G. -V. Roeschenthaler // Journal of Fluorine Chemistry. - 2000. - Vol. 102, № 1-2. - P73-77

Аннотация: The interaction of (E)-1,1,1-trifluoro-4-phenyl-but-2-ene-4-one (1) with trimethyl phosphite affords in a [4 + 1] cycloaddition the 1,2?5-oxaphospholene 2 as a sole product which upon hydrolysis is transformed into the fluoroalkyl containing ?-ketophosphonate 4. When the reaction is carried out in the presence of small mounts of water, in addition to 2 as a main product, the phosphoric acid ester 6 of the enolic dimer of ketone 1 is also formed. The molecular structure of compound 6 (monoclinic P 2(1)/c with a = 2088.60(2), b = 1403.1(3), c = 1613.8(1) pm, ? = 90, ? = 100.97(1), ? = 90°, Z = 8) was determined, indicating two independent molecules with (RR) and (SS) configuration and disordered CF3 groups.????

    Fluoroaryl containing beta,beta-dioxoesters in the synthesis of fluorobenzopyran-4(2)-ones [Text] / S. P. Kisil', Ya. V. Burgart, V. I. Saloutin, O. N. Chupakhin // Journal of Fluorine Chemistry. - 2001. - Vol. 108, № 2. - P125-131

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Fluoroaryl containing ?,??-dioxoesters and their copper(II) chelates have been prepared by acylation of ethyl acetoacetate with 2,6-dimethoxy-3,4,5-trifluorobenzoyl, 2-methoxy-3,4,5,6-tetrafluorobenzoyl and pentafluorobenzoyl chlorides. Cyclization of these ?,??-dioxoesters leads to formation of substituted fluorochromones. Depending on conditions, 2-methyl-5-methoxy-6,7,8-trifluoro-3-ethoxycarbonylchromone hydrolyzed to 5-hydroxy-2-methyl-6,7,8-trifluorochromone or 5-hydroxy-2-methyl-6,7,8-trifluorochromone-3-carboxylic acid. The same chromone reacts with morpholine to form a seven-substituted product and ammonium hydroxide to give 3-iminoacetyl-4-hydroxy-5-methoxy-6,7,8-trifluorocoumarin. Hydrolysis of the latter affords 3-acetyl-4-hydroxy-5-methoxy-6,7,8-trifluorocoumarin. Ethyl-2-(2,6-dimethoxy-3,4,5-trifluorobenzoyl)-3-oxobutanoates undergoes ketone-splitting to 1-(2,6-dimethoxy-3,4,5-trifluorophenyl)-1,3-butandione????
