Ключевые слова (''Своб.индексиров.''): chiral azinylferrocenes--cross-coupling reaction--halogenated azines
Аннотация: Two synthetic routes to the chiral azinylferrocenes (CAFs) 5 and 15, key intermediates for the synthesis of new enantiomerically enriched P,N-ligands, have been compared. The first approach is based on the palladium-catalyzed cross-coupling reaction of halogenated azines with organozinc derivatives of ferrocenes (the Negishi reaction). The second approach exploits a new synthetic methodology, which provides a shorter pathway, through the direct C–H functionalization of aromatics by the C–C coupling of halogen-free (hetero)arenes with lithium ferrocenes bearing stereogenic C and S atoms. The palladium complexes of P,N-ligands have been used as catalysts for the Tsuji–Trost reaction, which proceeds with high enantioselectivity to give allylic substitution products in good yields.

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: The synthesis of a series of push-pull aryl and arylethynyl 2-(thiophen-2-yl) quinazoline derivatives is presented. The photophysical properties of the newly generated compounds are also described. Functionalization of the (2-thienyl) quinazoline fluorophore at the 5'-position with aryl and arylethynyl moieties was performed using bromination and subsequent palladium-catalyzed cross-coupling reactions. Optical studies revealed that 4-(diethylamino) phenyl and 4-(diphen-ylamino) phenyl derivatives emit green light upon irradiation, whereas their 4-(9H-carbazol-9-yl) phenyl, methoxyphenyl, thienyl and arylethynyl counterparts are characterized by blue light emission capabilities. The effect of protonation has also been studied, and the ability of some of these molecules to function as colorimetric and luminescent pH sensors has been demonstrated with significant color changes and luminescence switching upon the introduction of acid.

Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): xerogel--titanium dioxide--palladium
Аннотация: We demonstrate a few-step technique for the synthesis of PdO/TiO2 and Pd/TiO2 (0.1–2.0 wt % Pd) xerogels, which comprises hydrolysis of a palladium nitrate solution in titanium tetrabutoxide in the vapor atmosphere over an aqueous acetic acid solution, drying, and calcination of the material between 800 and 870°C. According to X-ray diffraction and electron microscopy characterization results, after calcination at 800°C the xerogels contained palladium in the form of PdO particles ≤3–5 nm in size. The highly dispersed palladium(II) oxide covered the surface of the rutile crystallites and filled pores in between. Throughout the range of Pd(NO3)2 concentrations studied, the PdO particles were identical in size. In the material calcined at 870°C, palladium had the form of metallic particles ranging in diameter from 55 to 420 nm. Raising the palladium nitrate concentration in titanium tetrabutoxide was shown to increase the average size of the Pd particles.

Аннотация: Immobilizing thiourea onto chitosan allowed using the polymer for the recovery of platinum groups metals (PGMs) in acidic solutions (up to 1–2M HCl concentrations). At low HCl concentration protonated amine groups may sorb chloroanionic metal species (electrostatic attraction mechanism); however, most of sorption proceeds through chelation on sulfur containing groups (less sensitive to acidic conditions). The bi-site Langmuir equation was used for fitting sorption isotherms. The sorption of PGMs was weakly affected by the composition of the solution (presence of high concentration of anions and base metals). Maximum sorption capacities for Pd(II) and Pt(IV) ranged between 274 and 330 mg g?1 in 0.25M HCl solutions and decreased to 150–198 mg g?1 in 2M HCl solutions: Pd(II) sorption was systematically higher than Pt(IV) sorption. The pseudo-second rate equation was used for modeling the uptake kinetics. Agitation speed hardly affected uptake kinetics indicating that external diffusion resistance is not the rate controlling step. Desorption yield higher than 85% were obtained using thiourea in 0.1M HCl solution. The adsorbents could be reused for at least three cycles

Аннотация: Chitosan was modified by grafting 2-pyridyl-ethyl moieties on the biopolymer backbone for the synthesis of a Platinum Group Metal (PGM) sorbent. The sorbent was tested for Pd(II) and Pt(IV) sorption from HCl solutions. Stable for HCl concentrations below 0.5 M, the sorbent reached sorption capacities as high as 3.2 and 2.6 mmol metal g?1 for Pd(II) and Pt(IV), respectively. Metal sorption mainly proceeds by electrostatic attraction in acidic solutions, though a contribution of complexation mechanism cannot be totally rejected. The resistance to intraparticle diffusion is the main controlling mechanism for uptake kinetics. While agitation speed has a limited effect on kinetics, metal concentration and sorbent dosage have a greater effect on the kinetic profiles. The intraparticle diffusivity varies between 3 ? 10?11 and 4.5 ? 10?10 m2 min?1. Thiourea (combined with HCl solution) is used for Pd(II) and Pt(IV) desorption. The resin could be desorbed and recycled for a minimum of five cycles maintaining high efficiencies of sorption and desorption

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
