    1. Cover Picture: Oxidation of Rh/Ce0.5Zr0.5O2 Reduced under Mild Conditions as an Initiator of n-Butane Oxidative Reforming at Ambient Temperature (ChemSusChem 11/2009) (page 981)

      The cover image shows the initiation of oxidative reforming (OR) of n-butane to produce H2 and CO over a Rh/Ce0.5Zr0.5O2 catalyst cooled in an ice bath. The catalyst generates heat internally though oxidation of the Ce0.5Zr0.5O2−x support, and is immediately heated above the catalytic autoignition temperature of n-butane combustion, which eventually drives OR. In their communication on page 1032, Katsutoshi Nagaoka, Katsutoshi Sato, Yusaku Takita, and co-workers from Oita University show that Rh/Ce0.5Zr0.5O2 is reduced sufficiently even under mild conditions (i.e., in an H2 atmosphere at 373 K) and in situ during OR, and the oxidation of the resultant catalyst triggers OR at an ambient temperature without any external heat input (even under nonadiabatic conditions). This research is considered to represent an innovative step in the development of self-sufficient reforming systems for a new generation of fuel cell application.

    1. Hydrates of Natural Gases and Small Molecules: Structures, Properties, and Exploitation Perspectives (pages 992–1008)

      Guido Barone and Elena Chianese

      Version of Record online: 17 NOV 2009 | DOI: 10.1002/cssc.200900076

      Thumbnail image of graphical abstract

      The methane hydrates, among other clathrate complexes, are important for the mining and chemical industries as a new energy source and as a basis for production of chemicals. On the other hand the exploitation of large reserves of hydrates and their use as a fuel source can contribute to global warming. These subjects, together with an overview of the structures and origins of methane hydrates, are the topic of this Review.

    1. The Phosphine-Catalyzed Wittig Reaction: A New Vista for Olefin Synthesis? (pages 1021–1024)

      Ian J. S. Fairlamb

      Version of Record online: 30 OCT 2009 | DOI: 10.1002/cssc.200900208

      Thumbnail image of graphical abstract

      The design of a catalytic manifold for the Wittig reaction is highlighted. Arsenine-, telluride-, and the recently discovered phosphine-catalyzed processes are discussed and placed into context with the related silyl-Reformatsky process. The specific type of phosphine oxide precatalyst employed is compared with an aza-Wittig process and related transformations.

    1. The Derivatization of Bioplatform Molecules by using KF/Alumina Catalysis (pages 1025–1027)

      James H. Clark, Thomas J. Farmer and Duncan J. Macquarrie

      Version of Record online: 19 OCT 2009 | DOI: 10.1002/cssc.200900193

      Thumbnail image of graphical abstract

      The solid base KF/alumina is a surprisingly effective catalyst for Michael additions and retro-Claisen condensations on unsaturated bioplatform molecules, providing green chemistry routes to a number of interesting molecular structures.

    2. Glycerol as a Bioderived Sustainable Fuel for Solid-Oxide Fuel Cells with Internal Reforming (pages 1028–1031)

      Jung Yeon Won, Heui Jung Sohn, Rak Hyun Song and Seong Ihl Woo

      Version of Record online: 14 OCT 2009 | DOI: 10.1002/cssc.200900170

      Thumbnail image of graphical abstract

      Fuel for thought: Glycerol, obtained as a byproduct during the production of biodiesel is an environmentally sustainable fuel. Here it is used as fuel for solid oxide fuel cells. The maximum power density is comparable to that of solid oxide fuel cells that use hydrogen.

    3. Oxidation of Rh/Ce0.5Zr0.5O2 Reduced under Mild Conditions as an Initiator of n-Butane Oxidative Reforming at Ambient Temperature (pages 1032–1035)

      Katsutoshi Nagaoka, Katsutoshi Sato, Sho Fukuda, Hiroyasu Nishiguchi and Yusaku Takita

      Version of Record online: 23 OCT 2009 | DOI: 10.1002/cssc.200900194

      Thumbnail image of graphical abstract

      Reform Act: Rh/Ce0.5Zr0.5O2 is reduced in a H2 atmosphere at 373 K (140 K lower than the catalytic autoignition temperature) and in situ by H2 during oxidative reforming (OR). Oxidation of the reduced catalyst triggers OR of n-butane at ambient temperature even under non-adiabatic conditions.

    4. Perfluoro-Tagged Gold Nanoparticles Immobilized on Fluorous Silica Gel: A Reusable Catalyst for the Benign Oxidation and Oxidative Esterification of Alcohols (pages 1036–1040)

      Roberta Bernini, Sandro Cacchi, Giancarlo Fabrizi, Sandra Niembro, Alessandro Prastaro, Alexandr Shafir and Adelina Vallribera

      Version of Record online: 20 OCT 2009 | DOI: 10.1002/cssc.200900211

      Thumbnail image of graphical abstract

      A recyclable gold catalyst is prepared by immobilization of perfluoro-tagged gold nanoparticles on fluorous silica gel and used in the oxidation of alcohols as well as in domino oxidation/cyclization processes and in the direct oxidative conversion of alcohols to esters under an oxygen atmosphere. The oxidation is also possible under solvent-free conditions.

    1. High Value Products from Waste: Grape Pomace Extract—A Three-in-One Package for the Synthesis of Metal Nanoparticles (pages 1041–1044)

      Babita Baruwati and Rajender S Varma

      Version of Record online: 19 OCT 2009 | DOI: 10.1002/cssc.200900220

      Thumbnail image of graphical abstract

      Rags to Riches: Red grape pomace extract and red wine are efficient three-in-one reagents for the synthesis of various metal nanoparticles, such as Au, Ag, Pd, and Pt. Exposure to microwave irradiation reduces the reaction times to seconds.

    2. Chemoselective Allylation of Ketones in Ionic Liquids Containing Sulfonate Anions (pages 1045–1050)

      Paola Galletti, Fabio Moretti, Chiara Samorì and Emilio Tagliavini

      Version of Record online: 30 OCT 2009 | DOI: 10.1002/cssc.200900198

      Thumbnail image of graphical abstract

      The presence of sulfonate anions is the key to achieving allylation of ketones and aldehydes by allyltributyltin in room temperature ionic liquids (RTILs). Sulfonate can be a constituent of the RTIL or can be added as sulfonic acid. Aryl alkyl ketones are poor reagents, which allow chemoselective allylation of dialkyl substrates. A mechanistic NMR study is also presented.
