The Role of Ru and RuO2 in the Catalytic Transfer Hydrogenation of 5‐Hydroxymethylfurfural for the Production of 2,5‐Dimethylfuran
Authors: Jae Jungho , Zheng Weiqing , Karim Ayman M. , Guo Wei , Lobo Raul F. , Vlachos Dionisios G. 
Published: February 2014

AbstractWe have previously shown that 2,5‐dimethylfuran (DMF) can be produced selectively from 5‐hydroxymethylfurfural in up to 80 % yield via catalytic transfer hydrogenation with 2‐propanol as a hydrogen donor and Ru/C as a catalyst. Herein, we investigate the active phase of the Ru/C catalyst by using extended X‐ray absorption fine structure, X‐ray photoelectron spectroscopy, and high‐resolution TEM analyses. The results reveal that RuO2 is the dominant phase in the fresh (active) catalyst and is reduced to metallic Ru during the reaction with the hydrogen produced in situ from 2‐propanol. The deactivation of the catalyst is correlated with the reduction of the surface of RuO2. Reactivity studies of individual phases (bulk RuO2 and reduced Ru/C catalysts) indicate that RuO2 mainly catalyzes the Meerwein–Ponndorf–Verley reaction of 5‐hydroxymethylfurfural that produces 2,5‐bis(hydroxymethyl)furan and the etherification of 2,5‐bis(hydroxymethyl)furan or other intermediates with 2‐propanol and that the reduced Ru/C catalyst has moderate hydrogenolysis activity for the production of DMF (30 % selectivity) and other intermediates (20 %). In contrast, a physical mixture of the two phases increases the DMF selectivity up to 70 %, which suggests that both metallic Ru and RuO2 are active phases for the selective production of DMF. The oxidation of the reduced Ru/C catalyst at different temperatures and the in situ hydrogen titration of the oxidized Ru/C catalysts were performed to quantify the bifunctional role of Ru and RuO2 phases. The mild oxidation treatment of the Ru/C catalyst at 403 K could activate the catalyst for the selective production of DMF in up to 72 % yield by generating a partially oxidized Ru catalyst.
A Mechanistic Study of Ni‐catalyzed Carbon Dioxide Coupling with Ethylene towards the Manufacture of Acrylic Acid

Published: February 2014

AbstractThe reaction mechanism of CO2 coupling with C2H4 by homogeneous Ni‐complexes bearing bidentate phosphorous ligands was studied by means of density functional theory calculations. The reaction is initiated by sequential coordination of C2H4 and CO2 to the Ni center, followed by a facile coupling step, which results in a stable nickelalactone intermediate. Subsequent decomposition of this intermediate through β‐H transfer is the rate‐determining step. Together with the following reductive elimination step to form acrylic acid they represent a strongly kinetically‐hampered process. Destabilization of the nickelalactone intermediate in the presence of large bite angle bidentate ligands has only a minor effect on the overall reaction energetics. Modifying the electronic properties of ligands is also not effective to drive the reaction in a catalytic manner. These studies indicate that the coupling reaction has to be enforced through an alternative route. It is predicted here that a base‐assisted decomposition of the nickelalactone intermediate represents a favorable reaction channel. The factors affecting the reactivity of this route are investigated. The best reactivity corresponds to the CH3OH‐solvated CH3ONa that allows the β‐H transfer step to proceed with a barrier of only 49 kJ mol−1.
[(NHC)Fe(CO)4] Efficient Pre‐catalyst for Selective Hydroboration of Alkenes
Authors: Zheng Jianxia , Sortais Jean‐Baptiste , Darcel Christophe 
Published: February 2014

Abstract[(IMes)Fe(CO)4] [IMes=1,3‐bis(2,4,6‐trimethylphenyl) imidazol‐2‐ylidene] complex was found to be an efficient pre‐catalyst for the hydroboration of functional alkenes in the presence of pinacolborane at room temperature. Notably, UV irradiation (350 nm) is important to promote this catalytic transformation. Interestingly, high chemo‐ and regioselectivities were observed as only anti‐Markovnikov boronate derivatives were obtained and various functional groups can be tolerated.
Electrochemical Recognition of Selective Lead Adsorption on O2‐Plasma‐Treated Carbon Nanotubes
Authors: Wei Yan , Yang Ran , Liu Jin‐Huai , Huang Xing‐Jiu 
Published: February 2014

AbstractLead(II) is a highly toxic contaminant in the environment, and its removal in aqueous solution is generally governed by sorption processes on both organic and inorganic nanomaterials. In this work, an electrochemical method is developed for direct monitoring of the selective adsorption of lead(II) to surface hydroxyl groups of O2‐plasma‐treated carbon nanotubes. After accumulation of lead(II) from aqueous solutions at the open circuit potential, square‐wave anodic stripping voltammetry is performed by immersing an O2‐plasma‐treated carbon‐nanotube‐modified electrode into a detection cell containing 0.1 M NaAc–HAc solution. The process includes desorbing and measuring the amount of previously adsorbed lead(II). Overall, lead(II) adsorption is studied as a function of both the concentration of lead(II) and the pH value.
Triazole‐Tailored Guanosine Dinucleosides as Biomimetic Ion Channels to Modulate Transmembrane Potential

Published: February 2014

AbstractA “click” ion channel platform has been established by employing a clickable guanosine azide or alkyne with covalent spacers. The resulting guanosine derivatives modulated the traffic of ions across the phospholipid bilayer, exhibiting a variation in conductance spanning three orders of magnitude (pS to nS). Förster resonance energy transfer studies of the dansyl fluorophore with the membrane binding fluorophore Nile red revealed that the dansyl fluorophore is deeply embedded in the phospholipid bilayer. Complementary cytosine can inhibit the conductance of the supramolecular guanosine channels in the phospholipid bilayers.
