Аннотация: Heating of NiCl2 · 6H2O with 10-fold excess of an oxime having an CH2 group (1–4) at 100 °C for 1 day in air leads to the formation of the dioxime/ato complexes [Ni(dioxime/ato)2] (5–8) formed due to a novel type of metal-mediated nitrosation. Compounds 5–8 were characterized by elemental analyses, FAB (5–7) or APCI (8) mass-spectrometry, IR, 1H and 13C{1H} spectroscopies (for 8), and X-ray structural study has been performed for 5 and 8; the corresponding ketones (9–12) were identified by LC–MS.

Аннотация: The condensation of 4-hydroxy-3,5-diphenyl-2-phenyliminothiazolidine with 5-fluoro-4-morpholino- and 5-fluoro-4-(4-methylpiperazino)-1,2-phenylenediamines leads to region-isomeric thiazolo[3,4-a]quinoxalines differing in substituents in positions 7 and 8 of the benzene ring. From the ratio of isomers formed it follows that the mesomeric effect of a fluorine atom in 1,2-phenylenediamines is comparable with the influence of an aminosubstituent

Аннотация: The complexation of 3,6-substituted 1,2,4,5-tetrazines with benzotriazole was studied theoretically based on the vibrational spectra. For model complexes, the energy was minimized by the geometrical parameters, and the spectral characteristics were calculated by the PM3 method. The shift of the bond vibration frequencies of the atoms involved in complexation after the formation of different various intermolecular contacts was determined. This made it possible to determine the type of intermolecular interaction and suggest the structures of the complexes

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: New tetranuclear Cu(II) complex [Cu4(L)4]·MeCN (1) with 2,6-di(5-trifluoromethyl-1H-pyrazol-3-yl)pyridine (H2L) was synthesized. It has been shown that treatment of 1 with selected aza-ligands (pyridine, 2,2′- and 4,4′-bipyridyl, 2,3,5,6-tetra-(pyridine-2-yl)pyrazine, 2,2′;6′,2″-terpyridine and 1,4-diazabicyclo[2.2.2]octane) leads to formation of other Cu(II) complexes with different nuclearity: [Cu(L)py2] (2), [Cu(L)(2,2′-bpy)] (3), [Cu(L)2(tppz)]·THF (5), [Cu(L)tpy]·C6H5CN (4), {[Cu2(L)2(4,4′-bpy)2]·(C6H5CH3)·MeCN}n (6) and {[Cu(L)DABCO]·2MeCN}n (7). Obtained compounds were characterized by IR spectroscopy, X-ray crystallography data, EPR and SQUID magnetic measurements. --------------------------------------------------------------------------------

Заглавие : Synthesis and physicochemical and catalytic properties of composites in the Sio2–Zro2 system
Место публикации : Inorganic materials. - 2020. - Vol. 56, № 4. - С. 430-436
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): acid-base properties--catalysis--composite--silica--specific surface area--zirconia
Аннотация: Using coprecipitation, a sol–sol method, and molecular layering, we have synthesized SiO2–ZrO2 composites with SiO2 : ZrO2 ratios from 1 : 1 to 9 : 1 and a large specific surface area, which increases with growth silicon-containing component concentration. Using adsorption of Hammett indicators, we have assessed the concentration of acid–base centers in the pK range 1.3–9.6, which has been shown to vary from 68 to 160 μmol/g. Elemental analysis and IR spectroscopy data have demonstrated the presence of not only water but also nitrate ions and carbon dioxide on the surface of the samples. It has been shown that the use of nanoparticulate SiO2–ZrO2 oxides as heterogeneous catalysts—promoters for (2S,4R)-4-hydroxyprolyl-(S)-1-phenylethylamine trifluoroacetate, a chiral inducer in the asymmetric Biginelli reaction, makes it possible to raise ee (enantiomeric excess) from 39 to 68% and the reaction yield from 29 to 55%.
