The activation of dioxygen is the major challenge in the catalytic oxygenation of hydrocarbons under mild conditions. In this study, the catalytic efficiency for the aerobic oxidation of toluene and its derivatives by using cobaltmeso-tetraphenylporphyrin was enhanced by using acetylacetone as the oxygen activator. The influences of reaction conditions such as solvent, different metalloporphyrin catalysts, temperature, pressure and acetylacetone loading were studied, as well as the kinetics of the oxidation. Various toluene derivatives could also be oxidized to the corresponding products in satisfactory yields with this catalytic system. Based on the characterization ofin situelectron paramagnetic resonance (EPR) andin situUV-vis spectroscopy, the catalytic mechanism was also proposed, in which acetylacetone served as the key initiator of the free radical in activating dioxygen.

The compositions of volatile compounds in fresh mushrooms varied with their genotype species, maturity and growth conditions. This study aimed to identify volatile compounds in five growth stages of two genotype (A15 and W192) Agaricus bisporus species and used mathematical analysis to explain result. A total of 67 different compounds were identified by HS-SPME-GC-MS. Nine key-aroma substances including alcohols, ketones and aldehydes were found by Venn diagram and odor activity values. This improved method can be quickly analyzed the different samples characteristic volatile compounds without time consuming through quantifications. The sum of aroma compounds concentration was highest in the seedling stage (0.5-1.5 cm) and decreased with growth. Meanwhile, benzene acetaldehyde and 3-octanone as dominate parts of overall-aroma maybe affected by benzaldehyde and 3-nonanon during the mushroom growth. Since the harvest stage (3-5 cm). The mushroom flavor of A15 is more abundant than that of W192, therefore, A15 is more suitable for industrial production.

An ultrasonic-assisted synthesis of bis-isoxazole derivatives was developed. Eight 3-(6-chloropyridin-3-yl)-5-{[(3-arylisoxazol-5-yl)methoxy]methyl}isoxazoles were synthesized by 1,3-dipolar cycloaddition reaction between substituted isoxazolyl alkyne compounds and 6-chloro-N-hydroxynicotinimidoyl chloride. The structures of the synthesized compounds were confirmed by HRMS, FTIR, H-1 and C-13 NMR spectroscopy. Wherein, the antifungal and antibacterial activities of target compounds were tested. The synthesized compounds 6a and 6h exhibited better antifungal activity in comparison with the standard drug itraconazole. The minimum inhibitory concentrations(MICs) of both compound 6a and compound 6h were both 4 mu g/mL against Candida albicans ATCC 10231.

Electrode materials that combine the high energy density of batteries and the high power density of supercapacitors become an increasing need for current and near-future applications. Ta2O5 delivers a high theoretical capacity but suffers from unsatisfactory rate capabilities. Here we prepare a structurally disordered Ta2O5 nanoparticle aerogel via a nonaqueous sol-gel process followed by CO2 super-critical drying. The resulting aerogels exhibit large surface area, high porosity, fast ion diffusion, and extrinsically pseudocapacitive Li+/Na+ storage behavior (through surface redox reactions). With these merits, when evaluated as anode material for both lithium-ion and sodium-ion half cells (LIBs and NIBs), the Ta2O5 aerogels show excellent rate capabilities (97.0 and 43.7 mA h g(-1) at 5000 mA g(-1) for LIBs and NIBs, respectively) and highly stable cycling performance (20000 cycles at 5000 mA g(-1) and 10000 cycles at 1000 mA g(-1) without obvious capacity fading for LIBs and NIBs, respectively). This work introduces Ta2O5, a typical conversion-type metal oxide without intrinsic pseudocapacitance, as a promising anode material with high extrinsic pseudocapacitance for both LIBs and NIBs, which may open the door to achieve high-rate alkali-ion storage with low synthesis cost for durable microbatteries.

Described here is a titanocene-catalyzed reaction for the synthesis of acetals and hemiaminals from benzylic ethers and benzylic amines, respectively, with pendant epoxides. The reaction proceeds by catalysis in single-electron steps. The oxidative addition comprises an epoxide opening. An H-atom transfer, to generate a benzylic radical, serves as a radical translocation step, and an organometallic oxygen rebound as a reductive elimination. The reaction mechanism was studied by high-level dispersion corrected hybrid functional DFT with implicit solvation. The low-energy conformational space was searched by the efficient CREST program. The stereoselectivity was deduced from the lowest lying benzylic radical structures and their conformations are controlled by hyperconjugative interactions and steric interactions between the titanocene catalyst and the aryl groups of the substrate. An interesting mechanistic aspect is that the oxidation of the benzylic center occurs under reducing conditions.

Quinolines and quinoline-containing macromolecules are renowned for their valuable biological activities and excellent materials properties. Herein, we validate a general strategy for the synthesis of chloro-containing quinoline, benzoquinoline and polybenzoquinoline variants via the aza-Diels-Alder reaction. The described findings could be ultimately implemented in other synthetic pathways and may open new opportunities for analogous quinoline-derived materials.

Polymer functionality greatly determines many of the key properties of these materials, such as glass-transition temperature, electrical and thermal conductivity, thermal stability, mechanical strength, and processability. Despite the importance of polymer functionality in determining material properties, the synthesis of functional polymers, with well-defined molecular weights and compositions, can still present a significant challenge, with many of the methods related to pre- or postpolymerization modification lacking synthetic scope, or requiring harsh functionalization conditions or transition-metal coupling reactions to install the desired functionality. Perfluoroaromatic systems are promising for the preparation of novel polymer architectures given that they can be readily functionalized using simple nucleophilic chemistries under very mild basic conditions. While promising, these systems have displayed some drawbacks. Previous work has shown that perfluoroaromatics, such as perfluoropyridine, can demonstrate a high degree of chemical reversibility with heteroatom nucleophiles. If the synthetic potential of these systems is to be realized, then a strategy for the rational design of stable monomers must be developed. Herein, we report the design, synthesis, and characterization of a series of unexplored heteroatom-based ring-opening metathesis polymerization (ROMP)-active monomers containing a reactive perfluoropyridine pendent group, which can be used to readily prepare a wide variety of aryl ether-functionalized polymers, using both pre- and postpolymerization modification strategies. We also establish a direct connection between the dihedral angle of the monomer and its propensity to undergo reversible addition reactions, establishing functional criteria for the design of pre- and postmodifiable systems.

Terminaliamide (1), a new ceramide was isolated from the roots of Terminalia mantaly H. Perrier (Combretaceae) along with 4 known compounds (2-5). The structures of the compounds were elucidated using 1D and 2D NMR spectroscopy analysis and mass spectrometry. Compound 1 exhibited moderated antibacterial activity towards Staphylococcus aureus with MIC value of 62.5 mu g/mL. The crude MeOH extract (TMr) highly reduced Plasmodium falciparum growth with an IC50 value of 10.11 mu g/mL, while hexane fraction (F1) highly reduced Trypanosoma brucei brucei growth with an IC50 value of 5.60 mu g/mL. All tested samples presented little or no in vitro cytotoxicity on HeLa cell line. The present work confirms that T. mantaly is medicinally important and may be used effectively as an antimicrobial, an antiplasmodial and an antitrypanosomial with promising therapeutic index.
