Заглавие : Unusual synthesis of triosmium carbene clusters by tandem activation of chlorohydrocarbons and heterocyclic amines
Место публикации : European journal of inorganic chemistry. - 2021. - № 10. - С. 989–996
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The carbene ligand is assembled on a cluster core of two dichloromethane and one morpholine at room temperature, which is the first example of carbene ligands formed in this way. Clusters with a carbene ligand exist as two stable isomers, as confirmed by NMR studies and conformational analysis. Possible mechanistic pathways for the formation of clusters with carbene and enamine ligands are proposed.

Аннотация: A new type of intramolecular cyclization of 1,5-bis[2-(E-3-oxo-3-phenylprop-1-enyl)-phenoxy]-3-oxapentane with 3-aminotriazole promoted by potassium ions was discovered. A cascade mechanism for the formation of crownophane with 4,7-dihydro[1,2,4]triazolo[1,5-a]-pyrimidine fragment was suggested. Effects of oligooxyethylene fragment of the chalcone podand and acid-base catalysis on the selectivity of the cyclocondensation processes and degree of oxidation of triazolopyrimidine fragments were studied. The product structures were confirmed by IR, 1H and 13C NMR spectroscopy and X-ray diffraction study

Аннотация: Thiocarbamoyl chitosan (TCC) was synthesized by grafting thiourea on chitosan backbone in eutectic composition of ammonium thiocyanate—thiourea. Insoluble products with the amno group functionalization degree of 0.3–1.1 can be prepared by varying the conditions of polymer-analogous (synthesis in a gel) transformation. Structure of the synthesized chitosan derivatives was characterized by elemental analysis, diffuse reflectance infrared spectroscopy, and the solid state 13C NMR. Study of sorption properties of TCC shows high sorption capacity and selectivity for the ions of gold(III), platinum(IV), and palladium(II) as evidenced by results obtained at pH 2 in the presence of 100–1000-fold excess of iron(III), copper(II), zinc(II), and nickel(II). Sorption capacity of TCC for all ions increases with the increase in the degree of substitution and changes in the series: AuIII PdII PtIV

Аннотация: 4-Phenyl-2,6-bis(trifluoroacetyl)cyclohexanone and its dilithium salt were synthesized starting from the commercially available 4-phenylcyclohexanone. With X-ray structure analysis of these compounds, for the first time the solid state structure determination for a fluorinated 1,3,5-triketone and an alkaline salt of 1,3,5-triketone was achieved. The subsequent multinuclear NMR and MS investigations revealed that in solution and gas phase, analogously to the crystal, both compounds exist predominantly in a highly delocalized double U-enol(ate) form. The carbonyl O…O distances in the dilithium salt were established to be considerably longer than the distances between oxygens of the parent 1,3,5-triketone, bonded by strong (short) resonance assisted hydrogen bonds. Among the 1,3,5-tricarbonyl compounds with known crystal structure, the entitled 1,3,5-triketone shows comparatively weak delocalization over the conjugated bis-enolone backbone.

All complexes have been characterized by H-1, B-11 and F-19 NMR, mass-spectrometry and X-ray crystallography data. Some complexes have been found to exhibit a significant fluore.scence in acetonitrile solutions. Electronic and site effects of substituents in both heterocyclic and phenol fragments proved to have a profound impact on quantum yields.

Аннотация: Photoinduced transformations of 2-styrylquinazolinones in solutions were studied using absorption and NMR spectroscopy methods. A possibility of control of the photochemical isomerization rate of quinazolinone 2-(hydroxyaryl)ethenyl derivatives by changing the pH of the medium was demonstrated. The bases and the solvent nature also affect the luminescence intensity of solutions of these compounds in the wavelength range of 550-650 nm. The differences in the steric organization of the ortho-hydroxystyryldiazinone system in crystals and in solutions related to the turn of the aryl group were found. Their influence on the competing processes of luminescence and photochemical transformation of the ethylene fragment were shown. The fact of reversible photo/thermal E-Z-isomerization was established for (E)-2-(2-hydroxystyryl)-3-phenylquinazolin-4(3H)-one.

Ключевые слова (''Своб.индексиров.''): azaheterocycles--bnct--cytotoxicity--carboranes
Аннотация: A series of novel water-soluble azaheterocyclic derivatives of nido-carborane bearing quinoxaline, 2H-imidazole or 1,2,4-triazine moieties were first synthesized in 82–91% yields. The structures of these boron-enriched compounds were confirmed by the data of NMR, IR spectroscopy, and mass spectrometry. To access the toxicity level for these organoboron compounds, the cytotoxicity indexes (IC50) were determined using by the MTT test on both human glioblastoma cell A-172 (IC50 = 150–243 μM) and human embryonic lung cells (IC50 = 424–944 μM) lines. The obtained preliminary results from in vitro analysis enable the synthesized water-soluble azaheterocyclic carboranes to be considered as challenging candidates in the design of agents for boron-neutron capture therapy (BNCT) of malignant tumors.

Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The suspension polymerization in octafluorobutane, initiated by Ziegler–Natta catalyst system, has been used to synthesize ultra-high molecular weight poly(1-hexene), poly(1-octene), and poly(1-decene) of regular structure with high yields. This technique makes it possible to successfully carry out reactions at close to room temperature, followed by easy isolation of polymer products. The regularity of the structure of the synthesized polymers was proved based on the data of 1H and 13C NMR spectroscopy. Using gel permeation chromatography, data on the molecular weight distribution of polymer molecules were obtained. They indicated that the weighted average mass of the synthesized polymers is many times higher than the mass of polyolefins produced by the classical technique of homogeneous polymerization.
