Аннотация: O- and C-Adducts of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium salts are latent sources of biradicals capable of forming tetraazaphenanthrene derivatives via dimerization. The mechanisms of the reactions were examined using ESR spectroscopy. The stereochemistry of the resulting heterocyclic systems was studied by NMR spectroscopy. The crystallographic data on their three-dimensional structures were obtained

Аннотация: C-Adducts of 5-(het)aryl-2,3-dicyano-1-pyrazinium salts containing a residue of a 1,3-dicarbonyl compound at position 6 can be involved in the cyclization with hydrazine hydrate giving rise to pyrazino[2,3-c]pyridazines along with the expected pyrazole derivatives. The reactions of the same ?H-adducts with hydroxylamine unexpectedly afforded triazacyclopenta[a]indene derivatives. The crystallographic data on the three-dimensional structures of new polycyclic compounds were obtained

Ключевые слова (''Своб.индексиров.''): organic dyes --pyrimidine--microwave-assisted
Аннотация: Six novel donor–π–acceptor organic dyes bearing a pyrimidine as the anchoring group have been obtained in good yields by combination of the microwave-assisted Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen reactions. Their absorption, photoluminescence and electrochemical properties were fully investigated in detail. The infrared spectra of dyes adsorbed on TiO2 indicate the formation of coordinate bonds between the pyrimidine ring of dyes and the Lewis acid sites (exposed Tin+ cations) of the TiO2 surface. This work demonstrates that the pyrimidine rings of dye sensitizers that form a coordinate bond with the Lewis acid site of a TiO2 surface are promising candidates as the electron-withdrawing anchoring group. The data from quantum calculations show that all of the dyes are potentially good photosensitizers for dye-sensitized solar cells

Ключевые слова (''Своб.индексиров.''): 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.

Аннотация: The Petasis reaction of 6-hydroxy adducts of 1-alkyl-2,3-dicyano-5-arylpyrazinium salts with trans-styrylboronic acids proved to proceed smoothly at room temperature to give the corresponding 5-(hetero)aryl-6-styryl substituted 1,6-dihydropyrazine derivatives. Also it has been found that C(6) unsubstituted 1,6-dihydro- or 1,4,5,6-tetrahydropyrazine derivatives can be easy prepared in high yields from the corresponding pyrazinium salts by reduction with triethylsilane. All synthesized compounds were screened in vitro for their antifungal activities against seven pathogenic fungal strains and antimycobacterial activities against Mycobacterium tuberculosis H(37)Rv, avium, terrae and multi-drug-resistant strains isolated from tuberculosis patients in the Ural region (Russia)

Аннотация: The behavior of 4-thienyl substituted pyrimidine ligands (L1-3) has been studied for the series of their reactions with various salts of 3d metals (Co, Zn, Ni, Cu) and platinoids (Pt, Pd). In particular, mononuclear Co(OTf)(2)(L1-3)(2)(H2O)(2)(MeCN)(2) (1), binuclear Co-2(Piv)(2)(L1-3)(4) (2a,b), Cu-2(Piv)(2)(L1-3)(2) (5a,b), heterometallic polynuclear Li2Co2(Piv)(6)(L1-3)(2) (4) and chelate [(L-1)Pd(OAc)](2) (6) complexes have been obtained. The structures of all complexes have been established by X-ray diffraction. Also magnetic properties of coordination compounds 1, 2, 4 and 5 have been studied in details. In particular, mononuclear Co(II) complexes I and 4 proved to exhibit paramagnetism with large positive zero-field splitting parameters. Dinuclear Co(II) complexes 2a,b show weak antiferromagnetic interactions. Dinuclear Cu(II) complexes 5a,b demonstrate strong antiferromagnetic superexchange interactions via four carboxylate bridges. The systems 2a,b and 5a,b are isolated as exchange coupled dimers

Аннотация: Novel 1,4-diazine-based dyes of the D–π–A type, possessing triphenylamine as an electron-donating group, have been developed. Fluorescence studies have demonstrated that emission of these fluorophores is sensitive towards different nitroaromatic compounds and aliphatic amines, both in solutions and in a vapor phase. Moreover, these compounds can be considered as “naked-eye” fluorescent probes for solution polarity because they possess pronounced solvatochromic properties. Therefore, these compounds have to be regarded as potential multifunctional chemosensors for monitoring hazardous organic substances.

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

Ключевые слова (''Своб.индексиров.''): pyrazines--antituberculosis activity--2(1h)-pyrazinone
Аннотация: A simple method based on hydrolysis of 2,3-dicyanopyrazinium salts has been used for the synthesis of the corresponding 5-(hetero)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones. Also, the series of novel 1-ethyl-5-(hetero)aryl-1,6-dihydropyrazine-2,3-dicarbonitriles have been obtained through reduction of the same pyrazinium salts with triethylsilane. The obtained compounds proved to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, Mycobacterium avium, Mycobacterium terrae, as well as against rifampicin and isoniazid-resistance strains of Mycobacterium tuberculosis. The data for acute in vivo toxicity in mice have been obtained for these compounds which appear to be promising antitubercular agents
