An enantioselective route to the tetracyclic core structure of the novel antibiotic lead compound platensimycin is accomplished in 10 steps from simple commercially available starting materials. Highlights of this synthesis include (1) a regio- and enantioselective Diels-Alder reaction between methyl acrylate and methyl cyclopentadiene to give adduct 2 with essentially complete regio-, diastereo-, and enantiocontrol; (2) oxidative decarboxylation of ester 2 using nitrosobenzene; (3) a one-pot reductive cyanation of lactone 4; (4) a stereoselective intramolecular Michael addition between an alpha-branched aldehyde moiety and a beta-substituted enone part of 8, followed by aldol dehydration in one pot to give the Robinson annulation product 9.

New and unique electrocatalysis of gold for the carbonylation of methanol to dimethyl oxalate (DMO) and dimethyl carbonate (DMC) was found. The selectivity to DMO and DMC could be controlled over gold anode by electrochemical potential, as you like. Drastic changes of gold electrocatalysis was due to changes of the oxidation state of gold, Au0 or Au3+. Copyright

Red electrophosphorescence from light-emitting devices based on a ruthenium(II) complex [Ru(4,7-Ph2-phen)3] 2+-doped wide-band-gap semiconductive polymers, e.g., poly(vinylcarbazole) (PVK), polydihexyl-fluorene (PF), and ladder-like polyphenylene (LPPP), as the emitting layer are reported. These polymers show the short-wavelength electroluminescence emission peaking ranged from 410 to 490 nm, which overlaps well with the absorption band of [Ru(4,7-Ph 2-phen)3]2+; however, very efficient energy transfer was investigated in the PVK system, likely due to relative long excited-state lifetimes of PVK than that of PF and LPPP and good chemical compatibility of [Ru(4,7-Ph2-phen)3]2+ with PVK. The EL spectra show the characteristic spectrum of [Ru(4,7-Ph 2-phen)3]2+, with a peak at 612 nm and CIE of (0.62, 0.37) which is comparable with standard red color. The optimized device ITO/PVK 5 wt % [Ru(4,7-Ph2-phen)3]2+/PBD/ Alq3/LiF/Al shows the maximum luminance efficiency and power efficiency of 8.6 cd/A and 2.1 lm/W, respectively.

Manganese-catalyzed epoxidations of alkenes in bicarbonate solutions

This paper describes a method, discovered and refined by parallel screening, for the epoxidation of alkenes. It uses hydrogen peroxide as the terminal oxidant, is promoted by catalytic amounts (1.0-0.1 mol %) of manganese(2+) salts, and must be performed using at least catalytic amounts of bicarbonate buffer. Peroxymonocarbonate, HCO4-, forms in the reaction, but without manganese, minimal epoxidation activity is observed in the solvents used for this research, that is, DMF and tBUOH. More than 30 d-block and f-block transition metal salts were screened for epoxidation activity under similar conditions, but the best catalyst found was MnSO4. EPR studies show that Mn2+ is initially consumed in the catalytic reaction but is regenerated toward the end of the process when presumably the hydrogen peroxide is spent. A variety of aryl-substituted, cyclic, and trialkyl-substituted alkenes were epoxidized under these conditions using 10 equiv of hydrogen peroxide, but monoalkyl-alkenes were not. To improve the substrate scope, and to increase the efficiency of hydrogen peroxide consumption, 68 diverse compounds were screened to find additives that would enhance the rate of the epoxidation reaction relative to a competing disproportionation of hydrogen peroxide. Successful additives were 6 mol % sodium acetate in the tBUOH system and 4 mol % salicylic acid in the DMF system. These additives enhanced the rate of the desired epoxidation reaction by 2-3 times. Reactions performed in the presence of these additives require less hydrogen peroxide and shorter reaction times, and they enhance the yields obtained from less reactive alkene substrates. Possible mechanisms for the reaction are discussed.

For Ru and Ir oxide electrodes sintered at different temperatures, in this work, surface resistivity, X-ray photoelectron spectroscopy, electrode lifetime, voltammetric charge capacity, and total organic carbon of 4-chlorophenol (4CP) decomposition at the electrodes were measured, and then intermediates during the electrolysis were identified by gas chromatography-mass spectroscopy to predict the destruction path of 4CP at the electrodes. A sintering temperature of around 650C, rather than 400-550C suggested in the literature for the fabrication of Ru and Ir oxide electrode, showed the highest organic destruction yield. The sintering temperature strongly affected the electrode lifetime as well. During the high temperature sintering, increase of the sintering time caused the oxidation of the Ti substrate to result in the increase of oxide weight of the electrode and the solid diffusion of the generated TiO2 to the electrode surface, which decreased the electrode activity so that the organic destruction yield went down slowly. The destruction path of 4CP at a high temperature-sintered electrode was suggested to be different from that at a low temperature-sintered one. The Ru oxide electrode sintered at 450C generated several complicated aliphatic intermediates.

By adjusting the pH of the reaction medium, the stoichiometry, the reactant concentrations, and heating time and temperature, reactive mono-and binuclear Ru(III) and Rh(III) chloro aqua complexes and various hydrazone tautomers were obtained. This provided for the synthesis of new complexes promising as cardiotonic agents and analytical forms for determination of metal traces in solutions. Correlation analysis was applied to describe the type of M-L chemical bonding. The ruthenium formal oxidation state and local environment in the coordination polyhedra of the synthesized complexes were determined by X-ray photoelectron spectroscopy.

Rationally designed RuO2-based Deacon catalysts can contribute to massive energy saving compared to the current electrolysis process in chemically recycling HCl to produce molecular chlorine. Here, we report on our integrated approach between state-of-the-art experiments and calculations. The aim is to understand industrial Deacon catalyst in its realistic surface state and to derive mechanistic insights into this sustainable reaction. We show that the practically relevant RuO2/SnO2 consists of two major RuO2 morphologies, namely 2-4 nm-sized particles and 1-3-ML-thick epitaxial RuO2 films attached to the SnO2 support particles. A large fraction of the small nanoparticles expose {1 1 0} and {1 0 1} facets, whereas the film grows with the same orientations, due to the preferential surface orientation of the rutile-type support. Steady-state Deacon kinetics indicate a medium-to-strong positive effect of the partial pressures of reactants and deep inhibition by both water and chlorine products. Temporal Analysis of Products and in situ Prompt Gamma Activation Analysis strongly suggest a Langmuir-Hinshelwood mechanism and that adsorbed Cl poisons the surface. Under relevant operation conditions, the reactivity is proportional to the coverage of a specific atomic oxygen species. On the extensively chlorinated surface that can be described as surface oxy-chloride, oxygen activation is the rate-determining step. DFT-based micro-kinetic modeling reproduced all experimental observations and additionally suggested that the reaction is structure sensitive. Out of the investigated models, the 2 ML RuO2 film-covered SnO2 gives rise to significantly higher reactivity than the (1 0 1) surface, whereas the 1 ML film seems to be inactive.
