Xin, Lin published the artcileResearch on the Pollutant Migration Law Based on Large-Scale Three-Dimensional Similar Simulation Experiments of Underground Coal Gasification, HPLC of Formula: 91-15-6, the main research area is pollutant migration coal seam simulation underground gasification.

The potential pollution risk of underground coal gasification (UCG) has become a key factor restricting the development of UCG industrialization. Therefore, studying the migration and diffusion behavior of harmful pollutants is of great significance for preventing UCG pollution. In this paper, a large-scale three-dimensional similar simulation exptl. device for UCG is used to simulate the gasification of Tianjin fat coal under actual working conditions. The rock layer around the simulated coal seam was sampled after the gasification was completed, the contaminants in the samples were examined by XRD, and the changes in the relative content of the contaminants at different sampling points were studied by FTIR. The results showed that benzene, phenols, aldehydes, aromatic hydrocarbons, and aromatic heterocyclic compounds remained after the gasification of Number 7 sampling point in Qianjiang, Tianjin, and that the main pollutants were aromatic hydrocarbons. The migration and enrichment of phenol and aldehyde pollutants were about the same on the east and west sides of the gasification center, while benzene pollutants were more easily migrated and enriched than aromatic heterocyclic compounds The migration distance of phenolic pollutants on the south side of the gasification area is smaller than that of other pollutants and their maximum vertical distance from the gasification reaction area to the south is about 0.7 m. The results can provide a scientific basis for pollutant risk identification and prevention and control in the later UCG field test.

Xu, Chang published the artcileVisible-Light-Induced α-Amino C-H Bond Arylation Enabled by Electron Donor-Acceptor Complexes, Name: Phthalonitrile, the main research area is tertiary amine benzonitrile photochem regioselective arylation.

Enabled by electron donor-acceptor complexes, a novel visible-light-induced α-amino C-H bond arylation protocol, without a photoredox catalyst, was disclosed. The protocol does not require any transition metal, oxidant, or exclusion of oxygen or moisture. A direct irradiation of the mixture of tertiary amines and benzonitriles with visible light in N,N-diethylethanamide in the presence of Cs2CO3 afforded α-arylated amines in good to excellent yields.

Wang, Hui published the artcileSelective Coupling of 1,2-Bis-Boronic Esters at the more Substituted Site through Visible-Light Activation of Electron Donor-Acceptor Complexes, Product Details of C8H4N2, the main research area is photochem coupling regioselective diboronate aromatic nitrile preparation aryl ethylboronate; arylethyl boronate preparation diboronate coupling aromatic nitrile aryllithium directed; 1,2-Boron Shift; Alkyl Radicals; Boronate Complexes; Electron Donor-Acceptor Complexes; Photoactivation.

1,2-Bis-boronic esters are useful synthetic intermediates particularly as the two boronic esters can be selectively functionalized. Usually, the less hindered primary boronic ester reacts, but herein, we report a coupling reaction that enables the reversal of this selectivity. This is achieved through the formation of a boronate complex with an electron-rich aryllithium which, in the presence of an electron-deficient aryl nitrile, leads to the formation of an electron donor-acceptor complex. Following visible-light photoinduced electron transfer, a primary radical is generated which isomerizes to the more stable secondary radical before radical-radical coupling with the arene radical-anion, giving β-aryl primary boronic ester products. The reactions proceed under catalyst-free conditions. This method also allows stereodivergent coupling of cyclic cis-1,2-bis-boronic esters to provide trans-substituted products, complementing the selectivity observed in the Suzuki-Miyaura reaction.

Asai, Kento published the artcilePalladium-Catalyzed Benzylic Silylation of Diarylmethyl Carbonates with Silylboranes under Base-Free Conditions, Safety of Phthalonitrile, the main research area is palladium catalyzed benzylic silylation diarylmethyl carbonate silylborane; benzylic silane nucleophile preparation reaction carbon electrophile.

A palladium-catalyzed benzylic silylation of diarylmethyl carbonates with silylboranes has been developed. The reaction proceeds smoothly even under external base-free conditions, and the corresponding benzylic silanes are formed in good to high yields. The obtained benzyl silane derivatives can work as the benzylic nucleophiles by the action of a suitable fluoride source and react with some carbon electrophiles to deliver the corresponding benzylic C-C cross-coupled products. Addnl., while still preliminary, the allylic silylation of the isoelectronic allylic carbonates is also achieved.

Nechausov, S. S. published the artcileDual-curing propargyl/phthalonitrile monomers for composites by vacuum infusion process, Category: nitriles-buliding-blocks, the main research area is propargyl phthalonitrile monomer vacuum curing.

Four different bifunctional monomers were synthesized: two monomers containing N-propargylamine and phthalonitrile groups and two monomers containing O-propargyl ester and phthalonitrile groups. It was shown that only the latter one can be used to obtain composite materials by vacuum infusion (viscosity 40 mPa*s at 120°C). The N-propargylamine containing monomers demonstrated high viscosity of the melts and degradation with allene evolution while curing. Carbon fiber reinforced plastics (CFRP) were successfully obtained from 4-[3-(prop-2-yn-1-yloxy)phenoxy]benzene-1,2-dicarbonitrile by a vacuum infusion molding process. Mech. testing of the composites samples was performed. Influence of end-curing temperature on mech. properties and morphol. of composites was investigated. The curing temperature of 375°C critically affects the properties of the composite due to the high shrinkage. Composites cured at 375°C lost 18% of mech. properties at 300°C but cured at 330 only 10%. LOI for composites with a matrix of propargyl/phthalonitrile dual-curing polymers was equal to 75, which is higher than most materials obtained from thermosets.

Grudova, Mariya V. published the artcileAdducts of 2-Pyridylselenenyl Halides and Nitriles as Novel Supramolecular Building Blocks: Four-Center Se···N Chalcogen Bonding versus Other Weak Interactions, Related Products of nitriles-buliding-blocks, the main research area is pyridylselenenyl halide reaction nitrile; adduct pyridylselenenyl halide nitrile supramol building; selenadiazole halide preparation crystal mol structure.

Supramol. chem. of chalcogenadiazoles is attracting an increasing attention due to its applications in materials chem. Chalcogen bonding allows a fine-tuning of the self-assembly and, therefore, modulation of phys. properties when these compounds are employed. Here, authors report a facile preparation of a broad scope of 1,2,4-selenadiazoles via coupling of 2-pyridylselenenyl halides with unactivated nitriles, that represent a novel type of supramol. building blocks which eagerly engage in a variety of chalcogen bonding interactions. The substituent-dependent propensity of novel selenadiazoles for the formation of four-center Se···N chalcogen bonding is analyzed. Other weak interactions, which in some cases outcompete the formation of 2Se-2N squares, are described. The discovery of the adducts derived from α-halogenated nitriles, which form robust dimers featuring a very specific combination of 2Se-2N square, two Hal···Hal, and two Se···Hal noncovalent interactions, is presented.
