Аннотация: 5-Bromopyrimidine reacts with 2,2′-bithiophene, [2,2′:5′,2″]terthiophene and 2-phenylthiophene in the presence of a palladium catalyst to give 5-(het)aryl substituted pyrimidines due to the palladium-catalyzed aryl–aryl C–C coupling. 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

Ключевые слова (''Своб.индексиров.''): magnetostructural correlations--temperature dependent--magnetic susceptibility
Аннотация: We report on the synthesis and temperature-dependent magnetic properties observed in an exchange-coupled copper(ii) dimer using X/Q-band Electron Paramagnetic Resonance (EPR) spectroscopy (9/34 GHz). It has been found that the zero-field splitting (D) in the dimer changes gradually by a factor close to two in the temperature range from T = 50 to 300 K. X-ray diffraction data show that this dimer consists of two five-coordinated copper ions, one of which has a highly asymmetric geometry intermediate between square pyramid and trigonal bipyramid. The copper-copper distance in the dimer is temperature-independent, whereas the degree of trigonality in an asymmetric unit decreases as the temperature is lowered. Therefore we suppose that the observed dependence D(T) originates from the interplay of different exchange interaction pathways driven by these thermal changes. Magnetic susceptibility measurements reveal weak ferromagnetic interactions, whose anisotropic parts should indeed be very sensitive to the subtle changes in the geometry and may result in apparent D(T). Apart from being a very unusual example of magneto-structural correlations, this and similar dimeric systems can be considered as an interesting type of new materials exhibiting strongly temperature-dependent magnetic p

Ключевые слова (''Своб.индексиров.''): sol-gel method--zirconium oxychloride--silica-zirconia xerogels
Аннотация: The composite silica-zirconia xerogels have been prepared via sol-gel method using zirconium oxychloride, oxynitrate, acetate and sodium silicate as the precursors. The prepared materials have been characterized using FTIR, TG/DTA, EDX and surface area analyses. It has been established that surface area of silica-zirconia xerogels significantly depends on the zirconium source, but phase transitions and structural features of the xerogels seem to be unaffected by the choice of the zirconia precursor. Prepared xerogels increase the activity of chiral inductor in the asymmetric Biginelli reaction. The anion of the zirconium salt adsorbed on the surface of the synthesized material and the presence of Si-O-Zr heterolinkages determines the reaction yield. The highest chemo- and enantioselectivity towards formation of ee isomer have been provided by the catalyst prepared from zirconium oxychloride.

Аннотация: A short and robust approach for the synthesis of 2-(hetero)aryl substituted thieno[2,3-b]indoles from easily available 1-alkylisatins and acetylated (hetero)arenes has been advanced. The two-step procedure includes the "aldol-crotonic" type of condensation of the starting materials, followed by treatment of the intermediate 3-(2-oxo-2-(hetero)arylethylidene) indolin-2-ones with Lawesson's reagent. The latter process involves two sequential reactions, namely reduction of the C=C ethylidene double bond of the intermediate indolin-2-ones followed by the Paal-Knorr cyclization, thus affording tricyclic thieno[2,3-b]indoles.

Fluorescence studies have demonstrated that the emission of all derivs. is sensitive to the presence of nitroarom. explosives, such as 2,4,6-trinitrophenol (PA), 2,4,6-trinitrotoluene (TNT), and 2,4-dinitrotoluene (DNT), in their acetonitrile solns. The detection limits of fluorophores to PA, TNT, and DNT proved to be in the range from 5.83 × 10-6 to 2.38 × 10-7 mol/L, 1.70 × 10-4 to 8.40 × 10-6 mol/L, and 8.39 × 10-5 to 6.87 × 10-6 mol/L, resp. The theor. investigation into the quenching mechanism in the presence of fluorophore has been performed. All compds. have shown a good efficiency as sensor materials when tested as elements of the original device Nitroscan for detecting nitro-contg. explosives in vapor phase

A com. available 5-bromopyrimidine was used as the starting material to obtain various polycyclic systems through the sequence of nucleophilic arom. substitution of hydrogen (the SNH reaction), Suzuki cross-coupling and oxidative photocyclization. Evidence for the structure of benzo[g,h]dithieno[2,3-e:3',2'-j]perimidines has been obtained by X-ray crystallog. anal. MO calcns. (DFT), as well as redox and optical measurements for all new compds. have been performed. The data show that the reported polycyclic systems have potential for use in org. electronic applications. The synthesis of the target compds. was achieved using 5-bromo-4-(2-thienyl)pyrimidine and (phenyl)boronic acids as starting materials.

Аннотация: A series of new polycyclic compounds bearing the 5,11-dihydroindolo[3,2-b] carbazole ring system, as the common motif of their nine-ring scaffolds, has been successfully prepared with the usage of an efficient two-step strategy, based on the double Friedel-Crafts acylation of 5,11-dihexyl-6,12-di(hetero) aryl-substituted 5,11-dihydroindolo[3,2-b] carbazoles with 2-iodobenzoyl chloride in the presence of SnCl4, followed by regioselective palladium-catalyzed cyclization of the obtained 2,8-bis(2-iodobenzoyl) derivatives into the desired fused 9H-fluoren-9-ones. Some modifications of these nine-ring structures have been performed to afford compounds of the same family bearing the 9H-fluorene fragments. Basic photophysical and electrochemical properties as well as thermal stability of the new fused indolo[3,2-b] carbazole derivatives have been determined.

Аннотация: A series of D–π–A–π–D type dyes based on pyrimidines, bearing thiophene linkers, have been studied as sensing fluorophores. Fluorescence studies have demonstrated that the emission of all derivatives is sensitive to the presence of 2,4,6-trinitrotoluene (TNT) and other nitroaromatic compounds (NACs), in their acetonitrile solutions. The detection limits of fluorophores to NACs proved to be in the range from 10−4 to 10−6 mol/L. The time-resolved fluorescence measurements and theoretical investigation into the quenching mechanism in the presence of fluorophore has been performed. The two types of sensor prototypes for handheld sniffer «Nitroscan» (Plant «Promautomatika», Ekaterinburg, Russia) on the basis of non-woven dry wipe and spunlace non-woven fabric with various quantities of the most sensitive fluorophore have been fabricated. The reusable, reversible and sensitive response of the designed prototypes to NACs enables one to qualify these compounds as promising fluorescent sensory materials for detection of NACs.

Аннотация: The SN H methodology has successfully been applied for the direct C(sp2)-H functionalization of azaaromatics through the C-Li/C-H coupling of pentafluorophenyl lithium with azines and their N-oxides. As a result, a number of novel fluorinated biheterocyclic ensembles, that are of interest in the design of bioactive molecules and advanced materials, have been prepared in good to excellent yields under rather mild condition.
