15-05-2013 | Yigang Yan; Arndt Remhof; Daniel Rentsch; Young-Su Lee; Young Whan Cho; Andreas Züttel, Chemical Communication, 2013
Dodecaborates, i.e. the [B12H12]2− containing species, are often observed as main intermediates in the hydrogen sorption cycle of metal borohydrides, hindering rehydrogenation. In the decomposition process of Y(BH4)3, yttrium octahydrotriborate, i.e. Y(B3H8)3, rather than the stable ...

Levulinic acid (LA) is transformed into pyrrolidinones via iridium-catalysed reductive amination using formic acid as the hydrogen source in aqueous conditions. The catalytic system is the most active and performs under the mildest conditions ever reported for the reductive amination of LA.

The strategic incorporation of internal Lewis acids onto urea scaffolds gives rise to a family of tunable hydrogen bond donor catalysts. The nature of the Lewis acid and associated ligands affects the urea polarization, acidity, and activity in reactions of nitrocyclopropane carboxylates and ...
17-04-2013 | Xu Qin; Wenchun Xie; Sai Tian; Jiali Cai; Han Yuan; Zheng Yu; Glenn L Butterfoss; Anne Chudolij Khuong; Prof. Richar ..., Chemical Communication, 2013
α-Chymotrypsin catalyzed oligomerization of the “dipeptide lego” KL-ethyl ester (OEt) in aqueous media triggers a rapid sol-gel transition due to formation of alternating (KL)x. Resulting mixed chain oligomers, at alkaline pH, self-assemble into β-sheets. Thereafter, intermolecular backbone ...
17-04-2013 | Anders B. Laursen; Peter C K Vesborg; Ib Chorkendorff, Chemical Communication, 2013
This work describes a highly active and stable acid activated carbon fibre and amorphous MoSx composite hydrogen evolution catalyst. The increased electrochemical–surface area is demonstrated to cause the increased catalyst electrodeposition and activity. These composite electrodes also show ...
17-04-2013 | Antonio Frontera; Andres Tasada; Antonio Bauza; Miquel Barcelo-Oliver; Angel Garcia-Raso; Juan J Fiol; Elies Molins; ..., Chemical Communication, 2013
Two self-assembled hosts formed from Ag(I) salts and bis-pyrimidyl ligands are synthesized and X-ray characterized. Both are able to incorporate two anions in the structure combining hydrogen bonding and electrostatic interactions.
17-04-2013 | Li Yan Chan; Sunggak Kim; Taekyu Ryu; Phil Ho Lee, Chemical Communication, 2013
A highly efficient Pd-catalyzed ortho-alkenylation is reported using a mono-phosphoric acid-directing group for the first time. This phosphoric acid-directing group is successfully utilized for the synthesis of various alkenylated products and offers a new approach to ...
10-04-2013 | Xiaolong Wang; Tengyuan Zhang; Jun Yang, Chemical Communication, 2013
Polyelectrolytes were grafted to hydrocarbon surfaces by a dry-process and chemical-free approach using hydrogen projectiles with high kinetic energy but properly controlled selectively cleaving C-H bonds, on which electroless plating was carried out after loading Pd moieties by ion exchange ...
03-04-2013 | Sanaa Shenawi; Nimer Jaber; Joseph Almog; Daniel Mandler, Chemical Communication, 2013
Gold nanoparticles, AuNPs, capped with mercaptocarboxylic acids followed by silver precipitation develop latent fingermarks on paper as high quality “negative” impressions. This effect stems from hydrogen bonding between the carboxylic group and the paper cellulose and may improve the yield ...

Transformation of tetra(4-cyanophenyl)ethylene under Lewis acidic (ZnCl2) conditions at 400 °C leads to a porous covalent triazine-based organic framework (CTF) with high surface area (2235 m2/g), high CO2 and CH4 uptake and highest hydrogen uptake for a CTF material (1.86 wt% at 77 K, 1 bar).
