A silica-based network was used to immobilize ionic liquid-based ionogels and applied as a fiber coating for solid-phase microextraction (SPME). The ionogels were prepared by a sol-gel process, using two ionic liquids, triethylsulfonium bis(trifluoromethylsulfonyl)imide ([Set(3)][TFSI]) and 1-butyl-1-methylpiperidinium bis(trifluoromethylsulfonyl)imide ([C(4)C(1)Pip] [TFSI]), as well as their equimolar mixture. Methyltrimethoxysilane was used as the sol-gel precursor, and trifluoroacetic acid as a reaction catalyst. The fabricated ionogel fibers were evaluated as sorbent coating in headspace SPME combined with gas chromatography with barrier ionization discharge detection for volatile organic compounds (VOCs). The fibers showed a high affinity to aromatic VOCs, yielding good sensitivity and precision. Then, the developed method was applied to the analysis of aqueous samples. During the study, the main extraction parameters, i.e., salt concentration, extraction time, and temperature, were optimized for maximum fiber sorption and to maximize the enrichment factors. The average limits of detection were found to be 0.15 mu g L-1, 0.40 mu g L-1, and 0.07 mu g L-1, and the enrichment factors were in the 25700-61000, 33200-84700, and 29100-96500 ranges for [Set(3)], [C4C1 Pip] and [Set(3)/C4C1 Pip], respectively. The single fiber and fiber-to-fiber reproducibilities were below 11.2% and 30.6%, respectively. The results of this work suggest the possibility of fabricating selected extractants based on the physicochemical properties of the ionic liquids and target analytes.

The heterocyclic compound 2-amino-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide (1), designed using 2-chloro-6-methylaniline (2) as the start material, was successfully obtained via multiple synthesis route and finally characterized by IR, H-1 NMR, and single-cystal X-ray crystallography. To select the suitable candidates for tissue regeneration, the induction activity of the compound on the dental pulp mesenchymal stem cells (DP-MSCs) was evaluated. Firstly, the DP-MSCs cells were isolated and the cell colon formation ability was measured after compound treatment with cell colony determination. After that, the RT-PCT assay was conducted and the relative expression level of the genes related with cell osteogenesis and proliferation was further detected.

A concurrent tandem catalytic (CTC) methodology has been developed for the amidation of aryl chlorides where the aryl chloride is first converted to an aryl iodide via halogen exchange and the aryl iodide is subsequently transformed into the aryl amide. A variety of aryl chlorides were converted to aryl amides in up to 85% isolated yield using 20 mol % CuI, 60 mol % N,N’-cyclohexane-1,2-diamine, 2.2 equiv of K2CO3, and 1.05-1.5 equiv of amide in acetonitrile at 200 degrees C after 0.75-1 h. The same copper/ligand system served as multifunctional catalyst for both steps of the concurrent catalytic process with iodide present in substoichiometric amounts. Mechanistic studies were consistent with CTC amidation occurring via a nonradical mechanism. Kinetic modeling was conducted to investigate the effect of competitive direct amidation of an aryl chloride or aryl bromide on the formation of product over time during a CTC amidation reaction.

Most microplastics (MPs) have undergone extensive aging in the environment. Aged MPs exhibit different physical and chemical properties from unaged ones. Here, we studied the effects of accelerated aging on the characteristics and pyrolysis of commercial pigmented MPs, as well as pigments leaching and their interactions in simulated gastric and intestinal fluids of mammals. We report that the carbonyl index, surface area, and color change of MPs increased after aging treatment. Cracks and fragmentation of MPs facilitated the accessibility of light and oxygen to internal layer and therefore accelerated the aging process. TGA/GC-MS analysis showed that the high temperature resistance of MN decreased after aging. Thermal decomposition of pigments and polyethylene occurred in temperature ranges of 340-406 degrees C and 406-550 degrees C, respectively. Mono (di)-alkenes and saturated alkanes were the thermal decomposition products of polyethylene. Aging of MPs also caused an increased release of pigments and prolonged aging time led to more release in simulated fluids. Pigments would result in fluorescence quenching of the enzymes through binding interactions once they were released from MPs into simulated fluids. Charge neutralization and polymer bridging accounted for the formation of pigment-enzyme complexes and flocs. These novel findings will allow us to better assess how aging process affects the characteristics, leaching, and toxicity of MPs. (C) 2020 Published by Elsevier B.V.

Structural modifications of nicotinamide, a form of vitamin B3, gave rise to a series of compounds (8aa-8ce) that exhibit activities as type I positive allosteric modulators (PAMs) of human alpha 7 nAChR expressed in Xenopus oocytes in two-electrode voltage clamp assay. The compound 8ai was a potent and efficacious PAM with an EC50 = 3.34 +/- 1.13 mu M and the maximum activation effect of alpha 7 current over 1474 +/- 246% in the presence of acetylcholine (100 mu M). It is highly specific to alpha 7 nAChR over other subtypes of nAChR and 5-HT3A receptors. The structure-activity relationship analysis identified a key skeleton of nicotinamide nucleus critical for biological activity. Taken together, the 8ai as a type I PAM of alpha 7 nAChR may be beneficial for improvement of cognitive deficit.

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.

A series of core-shell Co-MOF-74@Mn-MOF-74 samples with different shell thicknesses were prepared by the seed growth method, which were characterized by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), inductively coupled plasma mass spectrometry (ICP-MS), X-ray photoelectron spectroscopy, nitrogen adsorption-desorption and scanning electron microscopy (SEM). The shell thickness of these MOF samples were successfully controlled by adjusting the mass ratio between MnCl2 center dot 4H(2)O and Co-MOF-74. On this basis, these MOFs were applied to the catalytic oxidation of toluene. The results showed that with the growth of Mn-MOF-74 in the outer layer of Co-MOF-74, the oxidative selectivity of the substrate to benzaldehyde was greatly improved for the synergy between the core layer and shell layer. The conversion of toluene was 22.4%, and the selectivity of benzaldehyde was 98.1%. In addition, the catalyst can transform various substituted toluene into the corresponding aldehydes in highly selectivity and still keep good stability after four catalytic cycles. The selectivity of the corresponding aldehyde is generally above 80%.

A series of new triazole ligands has been synthesized via copper-catalyzed cycloaddition reaction of readily available azides and alkynes. The synthesized compounds were characterized by FTIR, H-1 and C-13 NMR, and high-resolution mass spectra. The ligands provided excellent yields (up to 92%) in the palladium-catalyzed Suzuki-Miyaura cross coupling of unactivated aryl chlorides with phenylboronic acid. 1-Benzyl-4-(2,6-dimethoxyphenyl)-lH-1,2,3-triazole was found to be the most effective ligand due to the presence of electron-donating 2,6-dimethoxyphenyl substituent, which made it possible to develop a highly active ligand-catalyst system for the Suzuki reaction of aryl chlorides.
