Аннотация: The structures and characteristic features of the molecular packing patterns of complexes of pyridazines containing heterocyclic substituents and the carborane moiety with 2,3,5,6-tetrachlorohydroquinone (TCHQ) were investigated. It was shown that TCHQ can form supramolecular assemblies with carborane-containing substituted pyridazines. The stoichiometry and three-dimensional structures of these assemblies depend on the substituents in the pyridazine ring and are formed via O-H⋯N hydrogen bonding between TCHQ and heterocyclic molecules

ALIPHATIC HYDROCARBONS -- COAL TAR PITCH -- HIGH-BOILING SOLVENTS
Аннотация: The pyrolysis of polyethylene and polypropylene in vacuum residue and coal-tar pitch solvents was studied in a batch reactor at atmospheric pressure in a temperature range of 380-420 °C. Aliphatic hydrocarbons and C 5-C32 normal olefins and isoolefins were the main pyrolysis products of the polyolefins and vacuum residue, which also underwent thermal degradation at these temperatures. The total conversion of a polypropylene-vacuum residue mixture into gaseous and distillate products was nearly additive; upon the pyrolysis of polypropylene in pitch and of polyethylene in vacuum residue and pitch, the yield of distillate products decreased and the paraffin/olefin ratio in these products increased. The observed regularities were explained by hydrogen transfer from the solvents to the intermediate radical products of the thermal decomposition of polymer chains. The reactions of the resulting of olefins with the solvents can also occur to a lesser degree. The greatest deviations from additivity were observed in the pyrolysis of polyethylene in the solvents used

This two-step procedure can be regarded as nucleophilic substitution of hydrogen (SNH) on the heterocyclic ring of coumarins

Аннотация: Combination of the Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen (SNH) reactions proved to be a convenient method for the synthesis of 5-styryl-4-(hetero)aryl substituted pyrimidines from commercially available 5-bromopyrimidine. All intermediate 5-bromo-4-(hetero)aryl substituted pyrimidines and also the targeted 5-styryl-4-(hetero)arylpyrimidines were found to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, avium, terrae, and multi-drug-resistant strain isolated from tuberculosis patients in Ural region (Russia). It has been found that some of these compounds possess a low toxicity and have a bacteriostatic effect, comparable and even higher with that of first-line antituberculosis drugs

Аннотация: In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2, as an effective photocatalytic oxidative system. It has been shown that this versatile approach can be applied for direct C-H functionalisation of a variety of azaaromatic systems, such as mono-, di- and triazines, substituted and unsubstituted azines and their benzo-annelated analogues.

Аннотация: A comparative analysis of the structures of copper(II) and nickel(II) chelate complexes with N-substituted 2-aminoethanols, 3-aminopropan- 1 -ols, glycines and beta-alanines is performed. It is shown that tetradentate ligands based on 3-aminopropan- 1 -ol and P-alanine, sterically hindered 2-aminoethanol derivatives and tridentate enamino ketone derivatives tend to form oligonuclear copper(II) and nickel(II) complexes. Glycine derivatives do not provide the formation of oligonuclear copper(II) and nickel(II) complexes. The magnetic properties of a number of polynuclear complexes are compared.

Аннотация: The review considers the most typical examples of the direct non-activated non-catalytic C–C bond formation in arenes and their metal complexes activated by electron-withdrawing substituents in the aromatic nucleus and in hetarenes (azines and their N-oxides, porphyrins, etc.) upon the reactions with aliphatic and (hetero)aromatic (hetero)organolithium nucleophiles. Particular attention is given to the direct introduction of nitroxide radicals and (hetero)organic moieties into mono-, di- and triazines and their N-oxides. The influence of the structures of the (hetero)aromatic substrate and the (hetero)organolithium nucleophile on the reaction pathway and rate and on the structure of the reaction product is analyzed.

NUCLEOPHILIC-SUBSTITUTION -- DERIVATIVES -- HYDROGEN
Аннотация: 6-Styryl-5-(het)arylfurazano[3,4-b]pyrazines have been obtained by novel C-H functionalization, which is a particular case of the nucleophilic substitution of hydrogen (S-N(H)). The process is initiated by the Michael addition of morpholine at the C=C double bond of beta-nitrostyrenes, and the subsequent addition of the generated carbanion to C-6 of 5-(het)arylfurazano[3,4-b]pyrazines, followed by elimination of nitrous acid and morpholine. It has been shown that in this case, only beta-nitrostyrenes bearing electron-rich substituents on the aromatic ring are involved in arylalkenylation of furazano[3,4-b]pyrazines

PYRIMIDINES -- CARBAZOLE -- DYE-SENSITIZED SOLAR CELLS
Аннотация: Novel donor-pi-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

However 5-bromo-4-(het)aryl-pyrimidines have been prepared from the same starting materials through the SNH-reaction catalyzed by a Lewis acid. Conditions for both types of reactions were optimized. All components of the reaction mixtures, including by-products, have been elucidated by gas–liquid chromatography/mass-spectrometry. Evidence for the structure of 4- and 5-bithiophenyl-substituted pyrimidines has first been obtained by means of X-ray crystallography analysis. Molecular orbital calculations (TDDFT), as well as the redox and optical measurements for all new compounds have also been performed

Oxidation with sodium perborate and percarbonate provides high yields in trifluoroacetic acid. The lowest cost process consists in interaction with sodium monoperphthalate (Persol and phthalic anhydride) in an aqueous medium

1,2,4,5-TETRAZINES -- HETEROCYCLIC LEAVING GROUPS -- TETRAZINES
Аннотация: The reactions of 3,6-disubstituted and azoloannulated 1,2,4,5-tetrazines containing heterocyclic leaving groups with S-nucleophiles were studied. The methods of introduction of functionalized thiols, including thiol derivatives of 1,7- and 1,2-dicarba-closo-dodecaboranes, into the tetrazine ring were developed. It was established for the first time that, instead of replacement of a leaving group in the tetrazine ring, the attack of S-nucleophile at the unsubstituted carbon atom occurs in the case of imidazo[1,2-b][1,2,4,5]tetrazines to form previously unknown products of nucleophilic substitution of the hydrogen atom
