Nanosized alumina (Al2O3-NPs), a widely used nanoparticle in numerous commercial applications, is released into environment posing a threat to the health of wildlife and humans. Recent research has revealed essential roles of physicochemical properties of nanoparticles in determining their toxicity potencies. However, influence of shape on neurotoxicity induced by heterogeneous Al2O3 -NPs remains unknown. We herein compared the neurotoxicity of two shapes of gamma-Al2O3-NPs (flake versus rod) and their effects on metabolic profiles of astrocytes in rat cerebral cortex. While exposed to both shapes caused significant cytotoxicity and apoptosis in a dose-dependent manner after 72 h exposure, a significantly stronger response was observed for nanorods than for nanoflakes. These effects were associated with significantly greater ROS accumulation and inflammation induction, as indicated by increased concentrations of IL-1 beta, IL-2 and IL-6. Using untargeted metabolomics, significant alternations in metabolism of amino adds, lipids and purines, and pyrimidines were observed after exposure to both types. Moreover, changes in the metabolome caused by nanorods were significantly greater than those by nanoflakes as also indicated by physiological stress responses to ROS, inflammation, and apoptosis. Taken together, these findings demonstrated the critical role of morphology in determining toxic potencies of nanoalumina and its underlying mechanisms of toxic actions. (C) 2019 Elsevier B.V.

Effective synthesis of novel sulfamates from various carboxylic acids has been developed in the presence of chlorosulfonyl isocyanate (CSI) in mild conditions. Several acids, bases and solvents effects were investigated for one-pot synthesis sulfamates as a catalyst. Finally, triflic acid was found to possess efficiently under optimized conditions in acetonitrile. This method is easy, fair price and practical. It can be synthesized on grams and milligrams scale.

Futility of traditional advanced oxidation processes (AOPs) in saline wastewater treatment has stimulated the quest for novel halotolerant chemical oxidation technology. Acetylacetone (AA) has proven to be a potent photo-activator in the degradation of dyes, but the applicability of UV/AA for saline wastewater treatment needs to be verified. In this study, degradation of crystal violet (CV) was investigated in the UV/AA system in the presence of various concentrations of exogenic Cl- or Br-. The results reveal that degradation, mineralization and even accumulation of adsorbable organic halides (AOX) were not significantly affected by the addition of Cl- or Br-. Rates of CV degradation were enhanced by elevating either AA dosage or solution acidity. An apparent kinetic rate equation was developed as r = -d[CV]/dt = k[CV](a)[AA](b) = (7.34 x 10(-4) mM(1-(a+b)) min(-1)) x [CV](a=0.16) [AA](b=0.97). In terms of results of radical quenching experiments, direct electron/energy transfer is considered as the major reaction mechanism, while either singlet oxygen or triplet state ((3)(AA)*) might be involved. Based on identification of degradation byproducts, a possible degradation pathway of CV in the UV/AA system is proposed.

Triazolopyridinone derivatives are of high value in both medicinal and material chemistry. However, the chiral or hindered triazolopyridinone derivatives remain an underexplored area of chemical space because they are difficult to prepare via conventional methods. Here we report an electrochemical rearrangement for the efficient synthesis of otherwise inaccessible triazolopyridinones with diverse alkyl carboxylic acids as starting materials. This enables the efficient preparation of more than 60 functionalized triazolopyridinones under mild conditions in a sustainable manner. This method is evaluated for the late stage modification of bioactive natural products, amino acids and pharmaceuticals, and it is further applied to the decagram scale preparation of enantiopure triazolopyridinones. The control experiments support a mechanism involving an oxidative cyclization and 1,2-carbon migration. This facile and scalable rearrangement demonstrates the power of electrochemical synthesis to access otherwise-inaccessible triazolopyridinones and may find wide application in organic, material and medicinal chemistry. Chiral and hindered triazolopyridinone derivatives are an underexplored area of chemical space mainly due to their challenging synthesis via classical methods. Here, the authors report an electrochemical rearrangement for the synthesis of triazolopyridinones using diverse, available alkyl carboxylic acids as starting materials.

The 2-(neopentylsulfinyl)aniline directing group that promotes rapid palladium-catalyzed C-H acetoxylation and alkenylation of arylacetamides has been developed. The acetoxylation reaches completion within only 40 min at 100 degrees C and leads to the bis-functionalized products. Alternatively, the reaction can be carried out at room temperature, which is beneficial for sensitive substrates. For the alkenylation, we have developed a protocol in which easily available 1-substituted cyclopropanols were employed as equivalents of vinyl ketones.

The transformations of unactivated alkenes through C & xe001;C bond double cleavage are always attractive but very challenging. We report herein a chemoselective approach to valuable cyclic imides by a novel Cu-catalyzed geminal amino-oxygenation of unactivated C & xe001;C bonds. O-2 was successfully employed as the oxidant as well as the O-source and was incorporated into alkenyl amides via C & xe001;C bond cleavage for the efficient preparation of succinimide or glutarimide derivatives. Moreover, the present strategy under simple conditions can be used in the late-stage modification of biologically active compounds and the synthesis of pharmaceuticals, which demonstrated the potential application.

The copper-NHC-catalyzed carboxylation of organo-boranes with CO2 was investigated using computational and experimental methods. The DFT and DLPNO-CCSD(T) results indicate that nonbenzylic substrates are converted via an inner-sphere carboxylation of an organocopper intermediate, whereas benzylic substrates may simultaneously proceed along both inner- and outer-sphere CO2 insertion pathways. Interestingly, the computations predict that two conceptually different carboxylation mechanisms are possible for benzylic organoboranes, one being copper-catalyzed and one being mediated by the reaction additive CsF. Our experimental evaluation of the computed reactions confirms that carboxylation of nonbenzylic substrates requires copper catalysis, whereas benzylic substrates can be carboxylated with and without copper.

Little-explored hydrosilylation of ketenes promoted by main-group catalysts is reported. The boron Lewis acid tris(pentafluorophenyl)borane accelerates the slow uncatalyzed reaction of ketenes and hydrosilanes, thereby providing a convenient access to the new class of beta,beta-di- and beta-monoaryl-substituted aldehyde-derived silyl enol ethers. Yields are moderate to high, and Z configuration is preferred. The corresponding silyl bis-enol ethers are also available when using dihydrosilanes. The related trityl-cation-initiated hydrosilylation involving self-regeneration of silylium ions is far less effective.
