Аннотация: Reactions of 2-ethoxymethylidene derivatives of 1,3-dicarbonyl compounds with N,N-dimethylethane-1,2-diamine gave a number of 2-[(2-dimethylaminoethyl)amino]methylidene-1,3-dicarbonyl compounds which were subjected to regioselective quaternization at the tertiary nitrogen atom with methyl iodide. The resulting quaternary ammonium salts inhibited aggregation of cadmium and zinc sulfide sols in aqueous medium

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.

    Synthesis and physicochemical properties of nanostructured TiO2 with enhanced photocatalytic activity / I. B. Dorosheva, A. A. Valeeva, A. A. Rempel [et al.] // Inorganic Materials. - 2021. - Vol. 57, № 5. - P503-510

TITANIUM DIOXIDE -- SOL–GEL METHOD -- PHOTOCATALYSIS
Аннотация: Nanostructured titanium dioxide (TiO2) with a crystallite size from 10 to 85 nm, photocatalytically active for organic reactions under illumination with visible light, has been prepared by a sol–gel process using a titanium tetrabutoxide solution in ethanol with an initial pH of 6. According to X-ray diffraction characterization results, the as-prepared titanium dioxide was amorphous. Annealing in a hydrogen atmosphere for 1 h at 400°C led to the formation of an anatase phase, and annealing in the temperature range from 600 to 800°C resulted in the anatase–rutile phase transition. The crystallite size of titanium dioxide increased from 10 to 75 nm as the annealing temperature was raised from 400 to 1000°C (furnace annealing for 1 h) and from 60 to 85 nm as the annealing time at a temperature of 800°C was increased from 30 to 240 min. Diffuse reflection spectra showed that the band gap of TiO2 decreased from 3.3 to 2.6 eV as the annealing temperature was raised from 200 to 1000°C. The specific surface area data obtained by BET measurements showed that the samples annealed at the highest temperature (1000°C) had the smallest surface area, which dropped from 307 to 1m2/g. The efficiency of the synthesized TiO2 tested as a catalyst for oxidative S H N cross-coupling of acridine with indole demonstrated an in crease in product yield from 35 to 80% as the annealing temperature was raised to 800°C. Varying the 800°C annealing time from 30 to 180 min had no effect on the reaction product yield, which ranged from 70 to 80%.

    Synthesis and properties of azines functionalized graphene with extremely high adsorptive ability to Eu3+ ions / O. N. Chupakhin, A. A Musikhina, I. A. Utepova [et al.] // Flatchem. - 2022. - Vol. 33. - P100348
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: In this work, a versatile synthetic protocol for obtaining of new promising carbon materials based on the C–C coupling of graphenide lithium species with azaaromatic compounds (1,10-phenanthroline, phenyl-1,2,5-oxadiazolo[3,4-b]pyrazine) has been suggested. It was shown that more electrophilic oxadiazolopyrazine gave the product with high degree of graphene functionalization and demonstrated non-isomorphic properties. At the same time, phenanthrolinyl graphene has less functionalization degree due to a lower electrophilicity of azine. However, the large size of pores between organic residues in phenanthrolinyl graphene allows adsorbing almost 10% of Eu3+. The mesurment of adsorption isotherm showed an extremely high affinity of phenanthrolinylgraphene to Eu (III) ions in netural or alkaline conditions, and the obtained hybrid material could work at least 5 sorption/desorption cycles. The structures of azine-graphene dyads were verified by complex of modern physicochemical analyses methods (the Raman spectroscopy, FTIR, XPS, SEM, EDS and TGA analyses).
