  • Effect of post-annealing in air on optical and XPS spectra of Y2O3
           ceramics doped with CeO2
    • Abstract: Publication date: January–February 2019Source: Mendeleev Communications, Volume 29, Issue 1Author(s): Ivan S. Zhidkov, Roman N. Maksimov, Andrey I. Kukharenko, Larisa D. Finkelstein, Seif O. Cholakh, Vladimir V. Osipov, Ernst Z. KurmaevYttrium oxide ceramics doped with CeO2 (5 mol%) were prepared from nanopowders produced by the laser ablation method. The optical measurements have demonstrated that the transparency of as-sintered ceramic was markedly increased after annealing (T = 1400 °C) under air. XPS data revealed the presence of mixed Ce3+ and Ce4+ states, while oxygen defect peak decreased after annealing owing to the defect elimination during oxygen diffusion into the highly defective ceramic.Graphical abstractGraphical abstract for this article

Turbidimetry and laser Doppler microelectrophoresis showed that the synthesized compounds were incorporated into unilamellar dipalmitoylphosphatidylcholine (DPPC) vesicles.Graphical abstractGraphical abstract for this article
       
  • Effect of isomerization on the performance of aromatic hydrogen storage
           systems possessing different condensation extents
    • Abstract: Publication date: January–February 2019Source: Mendeleev Communications, Volume 29, Issue 1Author(s): Leonid M. Kustov, Alexander N. Kalenchuk, Sergei F. Dunaev, Victor I. BogdanThe influence of structural differences in cis- and trans-conformer molecules of ortho-, meta- and para-isomers of perhydroterphenyl and decalin on the hydrogen release in hydrogen storage systems was estimated for the Pt/C catalyst in a flow regime. The structural differences between the cis- and trans-conformers of perhydroterphenyl did not significantly affect the reactivity of its ortho-, meta- and para-isomers. In the case of decalin, the decrease in the volume of released hydrogen due to the conversion of its cis-isomer into the less active trans-form was clearly demonstrated.Graphical abstractGraphical abstract for this article

    • Abstract: Publication date: January–February 2019Source: Mendeleev Communications, Volume 29, Issue 1Author(s): Dmitrii L. Obydennov, Asmaa I. El-Tantawy, Vyacheslav Ya. SosnovskikhMajor methods for the preparation of triacetic acid lactone and its application as a bioprivileged compound in the synthesis of various valuable materials are summarized. Due to its structural features, this lactone belongs to both pyrones and polyketides, which provides opportunities for its obtaining by chemical and biological methods. The presence of several electrophilic and nucleophilic centers in its molecule, as well as its capability of undergoing transformations with both preservation and opening of the ring, ensure its multiple reactivity. Reactions proceeding without the ring opening lead to substituted and fused pyrans, while the ring opening provides N-heterocycles and acyclic derivatives.Graphical abstractGraphical abstract for this article

           solutions
    • Abstract: Publication date: November–December 2018Source: Mendeleev Communications, Volume 28, Issue 6Author(s): Margarita A. Gradova, Irina I. Ostashevskaya, Oleg V. Gradov, Anton V. Lobanov, Viktoriya S. Lebedeva, Andrey F. MironovPhotophysical parameters, photostability, aggregation behavior and photochemical activity of a new chlorin p6-based photosensitizer in micellar surfactant solutions were estimated. Despite the low fluorescence quantum yields, this compound demonstrates high photostability, and its photodynamic activity in micellar systems is comparable to that of the commercial photosensitizer Fotoditazin®, which makes this chlorin p6 derivative suitable for the interstitial photodynamic therapy of solid tumors.Graphical abstractGraphical abstract for this article
       
  • Synthesis of the acyclic precursor of an epothilone D analogue
    • Abstract: Publication date: November–December 2018Source: Mendeleev Communications, Volume 28, Issue 6Author(s): Ruslan F. Valeev, Gul’naz R. Sunagatullina, Raisa Z. BiglovaCondensation of separately obtained C1–C9 and C10–C21 chiral blocks under Yamaguchi conditions affords the corresponding ester, an acyclic precursor of an epothilone D analogue. The reaction is accompanied by the formation of a side product of acylation of the starting alcohol by the Yamaguchi reagent.Graphical abstractGraphical abstract for this article

           oxime with 1-aryl-1H-pyrazol-5-amines

TkachevChiral 1H-pyrazolo[3,4-b]pyridines fused with nopinane frame were obtained by FeCl3-catalyzed assembling of pinocarvone oxime and 1-aryl-1H-pyrazol-5-amines. Chemical structures of new compounds were solved by NMR spectroscopy and confirmed by quantum chemical calculations and X-ray crystallography.Graphical abstractGraphical abstract for this article

  • A new synthetic route to chiral 3-aryl-5-ethyl-1,4,2-oxazaphosphorines

AlfonsovDiastereoselective synthesis of racemic and enantiopure 3-aryl-5-ethyl-1,4,2-oxazaphosphorines, including those bearing phenolic hydroxyl groups in the exocyclic aromatic fragment, was implemented by the reaction of imines derived from (±)-and (R)-(−)-2-aminobutan-1-ol and (hydroxy)benzaldehydes with triethyl phosphite and trifluoroacetic acid, followed by the one-pot dealkylation of the intermediate esters.Graphical abstractGraphical abstract for this article
       
  • An original catalytic synthesis of boriran-1-ols
    • Abstract: Publication date: November–December 2018Source: Mendeleev Communications, Volume 28, Issue 6Author(s): Leila O. Khafizova, Liliya I. Khusainova, Tat’yana V. Tyumkina, Kirill S. Ryazanov, Natal’ya R. Popod’ko, Usein M. Dzhemilev2-Alkylboriran-1-ols were obtained in a one-pot process by hydrolysis of 1-fluoro- and 1-chloroboriranes in 90–92% yield. The starting 1-haloboriranes were generated by cycloboration of α-olefins with BCl3·SMe2 or BF3·THF in the presence of Mg metal (acceptor of halogen ions) and Cp2TiCl2 catalyst.Graphical abstractGraphical abstract for this article
       
  • Formation of 1,1-dichloro-2-vinyl-1-silacyclopropane by a photoinduced
           reaction between dichlorosilylene and 1,3-butadiene
    • Abstract: Publication date: November–December 2018Source: Mendeleev Communications, Volume 28, Issue 6Author(s): Sergey E. Boganov, Vladimir M. Promyslov, Stanislav S. Rynin, Irina V. Krylova, Mikhail P. EgorovA matrix FTIR study of interaction between SiCl2 and 1,3-butadiene revealed that at low temperatures, it stops at the step of complexation between the reactants. This allowed us to investigate a photochemical version of this interaction resulting in the formation of both 1,1-dichloro-1-silacyclopent-3-ene and 1,1-dichloro-2-vinylsilirane in contrast to the thermal reaction giving only the first of these products.Graphical abstractGraphical abstract for this article
       
  • Nanoscale heterogeneities in ionic liquids: insights from EPR of spin
           probes
    • Abstract: Publication date: November–December 2018Source: Mendeleev Communications, Volume 28, Issue 6Author(s): Mikhail Yu. Ivanov, Matvey V. FedinSelf-organization is an important property of room-temperature ionic liquids (ILs). In particular, it gives rise to various heterogeneities occurring on the nanometer scale. However, the detection and characterization of such heterogeneities is often challenging, and the development of new experimental approaches for such studies is highly demanded. In this work we review recent progress in applications of electron paramagnetic resonance (EPR) to study heterogeneities in ILs over a broad temperature range. Since ILs are naturally diamagnetic, various spin probes and corresponding techniques have been used. We demonstrate that complex application of continuous wave, pulse and time-resolved EPR allows one to obtain unique information on formation and properties of heterogeneities in ILs, fruitfully complementing the data of other methods.Graphical abstractGraphical abstract for this article
