alpha-(Hetero)aryl nitriles are important structural motifs for pharmaceutical design. The known methods for direct synthesis of these compounds via coupling with (hetero)aryl halides suffer from narrow reaction scope. Herein, we report that the combination of copper salts and oxalic diamides enables the coupling of a variety of (hetero)aryl halides (Cl, Br) and ethyl cyanoacetate under mild conditions, affording alpha-(hetero)arylacetonitriles via one-pot decarboxylation. Additionally, the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with alpha-alkyl-substituted ethyl cyanoacetates proceeds smoothly at 60 degrees C, leading to the formation of alpha-alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities and heteroaryls.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 126-83-0. The above is the message from the blog manager. Recommanded Product: 126-83-0.

The atmospheric SCC/pitting susceptibility of deposited MgCl2, synthetic sea-salt and site-specific sea-salt (containing ammonium and nitrate ions) on weld, HAZ and base 316L canister material was investigated. Higher SCC/pitting densities were observed for the HAZ region exposed to MgCl2, due to higher tensile residual stresses and plastic strains. Pitting in the weld region exposed to MgCl2 show preferential corrosion of delta-ferrite. Salt composition appears to have had a significant impact on SCC, pitting density and surface corrosion behaviour. Maximum surface crack propagation rates in the HAZ of 4 x 10(-11) ms(-1) were obtained for both synthetic sea-salt and MgCl2. (C) 2020 Published by Elsevier B.V.

The synthesis and solid state structural, spectral and electrochemical solution characterization of [Cu(L)(acpy)]ClO4 1 and [Cu(L)(NO3)]( )2 [where L = N'[(E)-phenyl(pyridin-2-yl)methylideneithiophene-2-carbohydrazide and acpy = 2,6-Diacetylpyridine] have been done by elemental analysis, UV-vis, FTIR, electrochemical techniques (CV and DPV) and electron paramagnetic resonance (epr) spectroscopy. The single crystal structures were solved by the X-ray diffraction technique. In complex 1, copper ion is in a distorted octahedral environment. The geometry of copper(II) in complex 2 is distorted square pyramidal (tau = 0.201). The mono deprotonated, HL ligand act as a tridentate to a copper(II) ion. On the basis of density functional theory (DFT) calculation, the electronic excitations involve transitions mainly from metal ligand bonding mostly the alpha-LUMO within the dominant Cu d(xy) character and to alpha-LUMO+1. Epr spectra for polycrystalline samples showed the copper(II) hyperfine features as well as half-field signal which are appropriate for Delta M-s = +/- 2 of dimers. Presence of half-field signal in 1 is due to solid-solid interaction (intra-molecular) where as in 2 the nature of interaction is intra-molecular. The antioxidant superoxide measurements show that the both complexes 1 and 2 behave as superoxide mimic in alkaline nitro blue tetrazolium chloride assay. (C) 2020 Elsevier B.V. All rights reserved.

In this work, the recycled acrylonitrile-butadiene-styrene (rABS)/anhydrous zinc chloride (ZnCl2) composites were prepared and the reinforcing effects of the rABS/ZnCl2 composites were investigated using various characterization techniques. During heat pressing at 190 degrees C, a strong coordination interaction occurred between Zn2+ of ZnCl2 particles and -CN groups of rABS matrix, which resulting in an enhancement of mechanical and thermal properties in comparison with the neat rABS. Fourier transform infrared spectroscopy, dissolution experiments, ultraviolet-visible spectroscopy, and X-ray photoelectron spectroscopy were applied to prove the coordination reaction. Scanning electron microscopy showed ZnCl2 particles were homogeneously dispersed in the rABS matrix. Tensile test analysis showed that the flexural strength and tensile strength of rABS/ZnCl2 composites increased by around 12.07% and 18.17%, respectively, when adding 7 phr of ZnCl2 into the rABS resin. Furthermore, heat deflection temperature analysis, thermogravimetric analysis as well as dynamic mechanical analysis proved that the coordination reaction dramatically improved the heat resistance of rABS matrix. Besides, the recycling ability of the composites had also been proved.

Abdominal aortic aneurysm (AAA) is a great threat to the health of elder (>50 years old) individuals. High salt intake is considered to raise the risk of AAA but the underlying mechanism remains to be elucidated. As endothelial dysfunction in the abdominal aorta is strongly associated with AAA, the present study hypothesized that high salt led to AAA by inducing apoptosis of endothelial cells. The present study verified that hypertonic medium with excess sodium chloride induced apoptosis of human umbilical vein endothelial cells (HUVECs), a commonly used cell model to study aortic endothelial cells. Further mechanism studies suggested that hypertonic conditions elevated the expression of nuclear factor of activated T cells 5 (NFAT5) and a high level of NFAT5 was capable of inducing apoptosis of HUVECs. In the investigation of downstream signals of NFAT5, it was identified that either hypertonic conditions or NFAT5 overexpression promoted the activity of NF-kappa B signaling pathway and subsequently suppressed the expression of anti-apoptotic protein Bcl-2. Thus, the present study demonstrated a novel mechanism by which high salt induced apoptosis of endothelial cells by enhancing the NFAT5-NF-kappa B signaling pathway. These findings will extend our knowledge about the pathogenesis of AAA and provide potential drug targets for the treatment of AAA.

Prodiginines and tambjamines are anion-selective ionophores capable of facilitating the transport of anions across the plasma membrane in mammalian cells. One of the potential applications of these anionophores is the possibility of employing them as a substitutive therapy for pathologies involving anion channels, as in cystic fibrosis. We have studied the interaction of a large anion as gluconate with three prodiginineand two tambjamine-like compounds. Apparent dissociation constants for the chloride, iodide and gluconate complexes were estimated from iodide influx experiments in mammalian cells exposed to different extracellular anion combinations. Our experiments indicate that gluconate is not transported by the prodiginines, leaving the anionophores free to transport chloride and iodide. Conversely, gluconate would be transported to some extent by the tambjamines, competing with halides for the anionophores, and consequently reducing their flux. This might be related to the different structural features of both families of compounds. These data have important implications for the selection of impermeable anions in the analysis of the anionophore mechanism.

Deep eutectic solvents (DES) formed by quaternary ammonium salts and hydrogen bond donors are a promising green alternative to organic solvents. Their high viscosity at ambient temperatures can limit biocatalytic applications and therefore requires fine-tuning by adjusting water content and temperature. Here, we performed a meta-analysis of the impact of water content and temperature on the viscosities of four deep eutectic solvents (glyceline, reline, N,N-diethylethanol ammonium chloride-glycerol, N,N-diethylethanol ammonium chloride-ethylene glycol), their components (choline chloride, urea, glycerol, ethylene glycol), methanol, and pure water. We analyzed the viscosity data by an automated workflow, using Arrhenius and Vogel-Fulcher-Tammann-Hesse models. The consistency and completeness of experimental data and metadata was used as an essential criterion of data quality. We found that viscosities were reported for different temperature ranges, half the time without specifying a method of desiccation, and in almost half of the reports without specifying experimental errors. We found that the viscosity of the pure components varied widely, but that all aqueous mixtures (except for reline) have similar excess activation energy of viscous flow E-eta(excess)= 3-5 kJ/mol, whereas reline had a negative excess activation energy (E-eta(excess)= – 19 kJ/mol). The data and workflows used are accessible at https://doi.org/10.15490/FAIRDOMHUB.1.STUDY.767.1.

Techniques using membranes for the treatment of wastewaters usually promote higher quality of treated water when compared to other processes. Among them, pervaporation has advantages in terms of selectivity in addition to low working pressure, which can prevent clogging problems. Polysulfone and polyurethane have complementary characteristics and are interesting in the context of membranes for industrial applications. In this sense, the aim of this work was to prepare and characterize polysulfone/polyurethane-based membranes and tested them with a simulated wastewater containing the reactive black dye and sodium chloride by pervaporation. In their manufacture, thermal treatment (at 60 degrees C) and photo-radiation treatment (using ultraviolet light) were also applied. The characterizations were performed using different analytical tools. In general, it was possible to verify that all membranes have a dense layer. The thermal analysis allowed to define that the indicated working temperature is below 50 degrees C. With respect to the simulated wastewater treatment, all membranes reached 100% selectivity. Concerning the saline solution, the mean selectivity was around 98.5%. Moreover, the permeate flow values were within the range presented by commercial membranes ranging from 1.6 to 2.4 kg m(-2) h(-1). Although for the photoirradiated membranes the photo-graft reaction has occurred, among all membranes, the blend without any treatment stood out from the others, presenting the highest permeate flow of the simulated wastewater. Finally, the results reveal that these membranes are capable of recovering wastewater from textile processes, in addition to having the potential to remove salts from water through the pervaporation process.

The molecular calcium hydride, [(BDI)CaF](2) (BDI = HC{(Me)CN-2,6-i-Pr2C6H3}(2)), effects the slow hydrodehalogenation of C6H5X (X = I, Br) to provide benzene and the respective dimeric calcium halides, [(BDI)CaX](2). Although a similar reaction with fluorobenzene was non-discriminating, the analogous hydrogenation of chlorobenzene was observed, albeit this process yields the calcium hydride-chloride as the alkaline earth-containing product. Assessment of the bromide- and chloride-based processes by density functional theory (DFT) calculations, imply that the reactions take place with the retention of the dimeric calcium structures throughout. Both systems invoke an S N Ar-type displacement of the halide, via barriers (in the range 32-34 kcal mol(-1) for C6H5Br and 31.1-32.9 kcal mol(-1) for C6H5Cl), which vary only marginally during the transformation of the initial hydride and halide-hydride intermediates. The isolation of the calcium hydride-chloride is ascribed, therefore, to its more rapid crystallisation and depletion from solution. Also reported is the reactivity of [(BDI)CaH](2) with alpha,alpha,alpha-trifluorotoluene and anisole, which yield the corresponding dicalcium hydride-fluoride and phenoxide derivatives, respectively, rather than the products of directed ortho metalation.

The detection of fraudulent additions to milk powder is an ongoing research subject for governmental agencies, industry and academia. Current developments steer towards the application of so-called fingerprint approaches, describing authentic, reference samples with spectroscopy and using one-class classification (OCC) to identify out-of-class, or adulterated samples. Within this article we describe the application of a novel, portable device hyphenating ultraviolet-visible, fluorescence and near-infrared spectroscopy in combination with OCC modelling to discriminate authentic skimmed milk powders from adulterated ones. As adulterated samples we analyzed skimmed milk powder with the addition of plant protein powder, whey powder, starch, lactose, glucose, fructose as well as non-protein nitrogen like ammonium chloride, ammonium nitrate, melamine and urea in different concentrations. After fusion of the classification results from the three spectral techniques and several models two scenarios are presented. 100% (scenario 1) or 80% (scenario 2) of the authentic skimmed milk powders were correctly identified as in-class, whereas respectively 64% or 86% of the adulterated samples were correctly classified as out-of-class. In brief, this article provides insights in the application of novel, portable devices that may be applied in a non-invasive manner and gives an outlook on data handling and a new data fusion strategy.
