Selective oxidation of ethers to lactones with O-2 as a benign oxidant using Au/CeO2 as the catalyst has been developed. The oxygen vacancies and Au-0 species on the surface of CeO2 contribute to the activation of O-2. The excellent selectivity of lactones is due to the adsorption of ethers and activation of the C(sp(3))-H bond on Au/CeO2.

Flotation reagents, especially new chelating agents represented by alpha-nitroso-beta-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of alpha-nitroso-beta-naphthol by simulated UVA-B (280-400 nm) activated systems using three common oxidants, hydrogen peroxide, sodium persulfate and potassium monopersulfate at a laboratory scale using a photoreactor. Parameters which can affect the degradation process were investigated and comparison of the degradation performance of the three systems were made. Based on the results, UVA-B/sodium persulfate system exhibited best performance towards the removal of alpha-nitroso-beta-naphthol with a lower cost of oxidant and energy consumption compared to the others. The removal efficiency was found to increase as the oxidant dosage and the UVA-B power increases. Only potassium monopersulfate could be activated by bicarbonate and chloride ions, and SO42- has insignificant effect on the removal efficiency of alpha-nitroso-beta-naphthol for all systems while NO3- inhibited the degradation of alpha-nitroso-beta-naphthol. In the UVA-B/hydrogen peroxide system, the hydroxyl radical had a leading role in the degradation of alpha-nitroso-beta-naphthol, while in the other two systems, the degradation of alpha-nitroso-beta-naphthol was mainly caused by the hydroxyl and sulphate radicals. Ten major intermediates from alpha-nitroso-beta-naphthol degradation in the three oxidation systems were identified by gas chromatography and mass spectrometry. In summary, this report could be a great input in developing UVA-B activated oxidants-based treatment technologies. The UVA-B/sodium persulfate system is strongly recommended for its consideration in the treatment of mine impacted wastewaters. (c) 2019 Elsevier Ltd. All rights reserved.

Phthalate derivatives with low estrogenic activity, high infrared spectrum signals, high Raman characteristic vibration spectrum, high fluorescence intensity, and high ultraviolet sensitivity were selected as precursors from our previous studies, so that the changes in their toxicity and estrogenic activity during biological metabolism, ozone oxidation, photocatalytic degradation, photodegradation, and microbial degradation could be studied.The transformation pathways of these derivatives were simulated, and the reaction energy barriers were calculated. To determine the potential environmental risks of these phthalate derivatives, the pharmacophore models of biotoxicity and estrogen activity of phthalates were used to predict the biotoxicity and estrogen activity of the transformed products. The results showed an increase in the biotoxicity and estrogen activity of the biometabolites, ozonation products, photocatalytic degradation products, and microbial degradation products; the only products that did not follow this trend were the photodegradation products. Notably, the pathways that produced more potentially toxic compounds were the less favorable paths. Our results indicate that the transformation products of the designed environmentally friendly phthalate derivatives potentially pose environmental risks. To avoid such risks, the environmental transformation pathway of these derivatives should be simulated to screen for environmentally friendly phthalate molecules. Environ Toxicol Chem 2020;00:1-11.

Chemoselective hydrogenation of phthalic anhydride is regarded as the most promising route for producing downstream high-performance phthalide. A series of intermetallic cobalt-nickel silicide catalysts embedded in a carbon matrix (CoxNi2-xSi@C) with acid-tolerance prepared by microwave-assisted chemical vapor deposition have been investigated in this reaction system. Activity measurements show a remarkable positive synergistic effect, forming a volcano-shaped plot over the nominal Co metal fraction for CoxNi2-xSi@C catalysts with a peak at x = 1.5, which corresponds to a 4.5-fold enhancement of the yield of phthalide over Co2Si@C and a 2.0-fold enhancement over the Ni2Si@C monometallic silicide catalysts, which can be correlated with the interaction of cobalt-nickel and metal-silicon bonds. In addition, the cobalt-rich bimetallic silicide exhibits an equal activity to the reference noble metal catalysts (Au, Pd, and Pt) and a significantly higher activity than transition metal catalysts. Moreover, the bimetallic silicide as an intermetallic compound catalyst has demonstrated robust acid corrosion resistance compared to the corresponding metal catalysts.

Pd(II)-catalyzed C-H lactonization of o-methyl benzoic acid substrates has been achieved using molecular oxygen as the oxidant. This finding provides a rare example of C-H oxygenation through Pd(II)/Pd(0) catalysis as well as a method to construct biologically important benzolactone scaffolds. The use of a gas mixture of 5% oxygen in nitrogen demonstrated the possibility for its application in pharmaceutical manufacturing.

Application In Synthesis of Isobenzofuran-1(3H)-one. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Phthalide derivative CD21 alleviates cerebral ischemia-induced neuroinflammation: Involvement of microglial M2 polarization via AMPK activation published in 2020, Reprint Addresses Du, JR (corresponding author), Sichuan Univ, Dept Pharmacol, Chengdu, Peoples R China..

Microglia can be activated to become the classic phenotype (M1) or alternative phenotype (M2), which play an important role in regulating neuroinflammatory response and tissue repair after ischemic stroke. CD21, a novel phthalide derivative, is a potential neuroprotectant against ischemic brain injury. The present study further investigated the effects of CD21 on post-ischemic microglial polarization and the underlying mechanisms. Transient middle cerebral artery occlusion (tMCAO) was used as a mouse model of ischemic stroke, while BV2 cells stimulated with conditioned medium collected from oxygen-glucose deprivation-treated HT22 cells were used in in vitro ischemic studies. The current results showed that CD21 dose-dependently and significantly improved neurological outcomes in tMCAO mice. Biochemical analyses revealed that CD21 decreased the expression of M1 phenotype markers (CD86, interleukin-1 beta and inducible nitric oxide synthase) and increased the expression of M2 phenotype markers (CD206, interleukin-10 and YM1/2) in both ischemic brain tissues and BV2 cells. Meanwhile, CD21 decreased the production of proinflammatory cytokines (interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha), promoted the release of the antiinflammatory cytokine (interleukin-10), and enhanced the phosphorylation of adenosine 5′-monophosphate-activated protein kinase (AMPK) in ischemic brain tissue and BV2 cells. Furthermore, the AMPK inhibitor (compound C) reversed these effects of CD21 in BV2 cells. These findings indicate that CD21 alleviates post-ischemic neuroinflammation through induction of microglial M2 polarization that is at least in part medicated by AMPK activation, suggesting that CD21 may be a promising candidate for protecting against ischemic brain injury.

Controlled, photocatalytic C-H bond activations are key reactions in the toolkits of the modern synthetic chemist. While it is known that the uranyl(VI) ion, [(UO2)-O-VI](2+), the environmentally dominant form of uranium, is photoactive, most literature examines its luminescent properties, neglecting its potential synthetic utility for photocatalytic C-H bond cleavage. Here, we synthesise and fully characterise an air-stable and hydrocarbon-soluble uranyl phenanthroline complex, [(UO2)-O-VI(NO3)(2)(Ph(2)phen)], U-Ph2phen, and demonstrate that it can catalytically abstract hydrogen atoms from a variety of organic substrates under visible light irradiation. We show that the commercially available parent complex, uranyl nitrate ([(UO2)-O-VI(NO3)(2)(OH2)(2)]center dot 4H(2)O; U-NO3), is also competent, but from electronic spectroscopy we attribute the higher rates and selectivity of U-Ph2phen to ligand-mediated electronic effects. Ketones are selectively formed over other oxygenated products (alcohols, etc.), and the catalytic oxidation of substrates containing a benzylic C-H position is particularly improved for U-Ph2phen. We also show uranyl-mediated photocatalytic C-C bond cleavage in a model lignin compound for the first time.
