      Brown and gold The cover picture illustrates the concept of using gold nanoparticle-decorated carbon nanotubes to directly electrochemically oxidize alginate—the principle, difficult-to-degrade component of brown macroalgae (as shown in the background of the cover picture). In their Full Paper on p. 135 ff., L. Q. Hoa, E. Tamiya et al. present analyses that suggest a reaction pathway similar to the chemical oxidation process by strong oxidants that results in oxidized alginate usable for cell and tissue engineering. This straightforward approach, in contrast to currently employed alginate-metabolizing microbial approaches, can enhance the energy extraction efficiency of the whole biomass-to-energy conversion process through a fuel cell system without requiring any external energy, while simultaneously producing high-value chemicals, paving the way for the future production of energy and feedstock materials from inedible biomass.

      Dr. Judith Scholz, Veit Hager, Dr. Xinjiao Wang, Florian T. U. Kohler, Michelle Sternberg, Dr. Marco Haumann, Dr. Normen Szesni, Prof. Dr. Karsten Meyer and Prof. Dr. Peter Wasserscheid

      Article first published online: 10 JAN 2014 | DOI: 10.1002/cctc.201490006

      Thumbnail image of graphical abstract

      Today's catalytic forecast: migrating front and hot spots The cover picture shows the conversion of ethylene to 1-butene and 2-butene by using a fixed-bed reactor with the catalyst bed consisting of supported ionic liquid phase (SILP) catalyst particles. In their Full Paper on p. 162 ff., P. Wasserscheid et al. describe that the applied homogeneous nickel complex exhibits a high activity and selectivity to 2-butene. The observed catalyst deactivation is attributed to a migrating reaction/deactivation front travelling through the catalyst bed in combination with hot spot formation. The time until catalyst deactivation could be heavily prolonged by optimization of catalytic and process parameters.

      Large Iodine: The site-selective oxidation of unactivated secondary sp3 C[BOND]H bonds was accomplished by using a newly defined reactive hypervalent iodine(III) radical in the presence of tert-butyl hydroperoxide (see scheme). Recent studies on hypervalent iodine radicals have significantly contributed to the further development and design of organic molecules in radical oxidation chemistry.

      Article first published online: 23 OCT 2013 | DOI: 10.1002/cctc.201300635

      Thumbnail image of graphical abstract

      Fisching for gasoline: The catalytic properties of mesoporous H-ZSM-5-supported Co catalysts for the direct synthesis of gasoline from syngas are studied. The improved selectivity toward gasoline fraction owes to the secondary acid-catalyzed reactions of the Fischer–Tropsch α-olefins over the zeolite. The addition of promoters improves the reducibility of Co, which leads to an increased initial catalytic activity. Nevertheless, promoters do not affect the product distribution significantly.

The tartaric acid-modified nickel catalyst prepared from the commercially available nickel powders without any pretreatment can catalyze the enantiodifferentiating hydrogenation of β-ketoesters to give the corresponding β-hydroxyesters in quantitative yield and high enantioselectivity (up to 91 %) under optimized conditions. This finding can pave the way for the practical application and industrial use of chirally modified nickel catalysts.

      Exchanges at the border: Oxygen exchange characteristics at terrace and border sites of an FeOx/Pt(1 1 1) ultra-thin film are obtained within a realistic strong metal–support interaction catalyst model by DFT+U calculations. Oxide–metal and oxide–oxide boundaries are found to easily adsorb and release oxygen and are thus potentially responsible for the observed low-temperature activity in CO oxidation.

      The proof is in the π: Under the conditions of dual activation catalysis with oxygen nucleophiles, β-substituted naphthalenes are obtained from 1,2-diethinyl arenes. Mechanistic studies support that dual activation leads to β-substituted naphthalenes, whereas α-naphthalenes are formed by π activation only, and no gold acetylide or dual activation is involved in the formation of the α-substituted products.
