Chiral phosphoric acid catalyzed oxidative kinetic resolution of cyclic secondary amine derivatives including tetrahydroquinolines by hydrogen transfer to imines

07-Oct-2015 | Kodai Saito; Hiromitsu Miyashita; Takahiko Akiyama, Chemical Communication, 2015

A chiral Brønsted acid catalyzed dehydrogenative kinetic resolution of tetrahydroquinoline derivatives, which are representative of cyclic secondary amines, based on their hydrogen transfer to aromatic imines was efficiently achieved with high enantioselectivities. This hydrogen transfer of ...


A self-assembled Pd2L4 cage that selectively encapsulates nitrate

07-Oct-2015 | Lipeng Zhou; Qing-Fu Sun, Chemical Communication, 2015

A M2L4 cage with D4 symmetry was self-assembled from four anthracene-bridged benzimidazole ligands and two PdII ions. The cage features a concise hydrophobic pocket wrapped up by the anthracene walls with eight hydrogen-bond donors pointing inward, which provide a specific binding site for ...


A New Approach for Bio-Jet Fuel Generation from Palm Oil and Limonene in absence of Hydrogen

07-Oct-2015 | Jingjing Zhang; Chen Zhao, Chemical Communication, 2015

The traditional methodology includes carbon-chain shortening strategy to produce bio-jet fuel from lipids via a two-stage process with hydrogen. Here, we propose a new solution using a carbon-chain filling strategy to convert C10 terpene and lipids to jet fuel ranged hydrocarbons with aromatic ...


Rational Design of Peptide-based Hydrogel Responsive to H2S

07-Oct-2015 | Raoul Peltier; Gan-Chao Chen; Haipeng Lei; Mei Zhang; Liqian Gao; Su Seong Lee; Zuankai Wang; Hongyan Sun, Chemical Communication, 2015

The development of hydrogels that are responsive to external stimuli in a well-controlled manner is important for numerous biomedical applications. Herein we reported the first example of a hydrogel responsive to hydrogen sulphide (H2S). H2S is an important gasotransmitter whose deregulation has ...


An amorphous CoSe film behaves as an active and stable full water-splitting electrocatalyst under strongly alkaline conditions

07-Oct-2015 | Tingting Liu; Qian Liu; Abdullah M. Asiri; Yonglan Luo; Xuping Sun, Chemical Communication, 2015

It is attractive but still remains a big challenge to develop non-noble metal bifunctional electrocatalysts efficient for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) under alkaline conditions. Herein, an amorphous CoSe film electrodeposited on a Ti mesh (a-CoSe/Ti) ...


Investigation of the Interaction Modes between Nonpolar Organic Pollutants with Ionizable Functional Groups and Natural Organic Matter via AuNPs-Based Colorimetric Assays

07-Oct-2015 | Hongyun Niu; Saihua Wang; Yixin Tan; Yaqi Cai, Chemical Communication, 2015

For the first time, natural organic matter (NOM) modified AuNPs are used as sensors to “observe” the specific interactions (such as hydrogen-bonds and halogen-bonds) between functional groups of organic compounds and NOM using the colorimetric assays.


The discovery of 9/8-ribbons, [small beta]/[gamma]-peptides with curved shapes governed by a combined configuration-conformation code

24-Sep-2015 | David J Aitken; Claire M Grison; Sylvie Robin, Chemical Communication, 2015

The de novo design of a β/γ-peptidic foldamer motif has led to the discovery of an unprecedented 9/8-ribbon featuring an uninterrupted alternating C9/C8 hydrogen-bonding network. The ribbons adopt partially curved topologies determined synchronistically by the β-residue configuration and the ...


High-Efficiency Dye-Sensitized Solar Cells up to 8.03% by Air Plasma Treatment[space]of ZnO Nanostructures

24-Sep-2015 | Yitao He; Jing Hu; Yahong Xie, Chemical Communication, 2015

By using the simple but effective method─air plasma to treat the precursor of Zn(OH)2, hydrogen-related defects in ZnO which lead to the increasing of thecharge carrier recombination has been reduced. Successfully, the photoelectric conversion efficiency of 8.03% for pure ZnO-based DSSCs has ...


Selective Conversion of Glycerol to Lactic Acid with Iron Pincer Precatalysts

24-Sep-2015 | Liam Sharninghausen; Brandon Mercado; Robert H Crabtree; Nilay Hazari, Chemical Communication, 2015

A family of iron complexes of PNP pincer ligands are active catalysts for the conversion of glycerol to lactic acid with high activity and selectivity. These complexes also catalyse transfer hydrogenation reactions using glycerol as a hydrogen source.


Hydride Ion Formation in Stoichiometric UO2

24-Sep-2015 | Joseph Malcolm Flitcroft; Marco Molinari; Nicholas Brincat; Mark Storr; Steve Parker, Chemical Communication, 2015

We investigated atomic hydrogen solubility in UO2 using DFT. We predict that hydrogen energetically prefers to exist as a hydride ion rather than form a hydroxyl group by 0.27eV, and that on diffusion hydrogen’s charge state will change. The activation energy for conversion of hydride to hydroxyl ...
