Recent Progress in Chemical Characterization of Supported Gold Catalysts: CO Adsorption on Au/Ceria–Zirconia |
|
Juan J. Delgado, José M. Cíes, Miguel López-Haro, Eloy del Río, José J. Calvino, and Serafín Bernal |
| [Full Text PDF(J-STAGE)] Open Access Article |
 |
| An approach correlating quantitative CO adsorption data with the nanostructural properties of Au/CeO2–ZrO2 catalysts is discussed. It has been used to show that the CO adsorption occurs on Au sites with coordination number ≤7, that Au dispersion has a dramatic influence on the amount of CO strongly chemisorbed on the support, and that a fully reversible SMSI effect may be induced by successive mild reduction and reoxidation treatments. |

Cross-coupling Reactions of Organoboranes: An Easy Method for C–C Bonding |
|
Akira Suzuki and Yasunori Yamamoto |
| [Full Text PDF(J-STAGE)] Open Access Article |
 |
| The Csp2–B compounds and Csp3–B compounds readily cross-couple with organic electrophiles to give coupled products selectively in high yields. Recently, the Csp–B compounds have been also observed to react with organic electrophiles to produce expected cross-coupled products. The overview of some of such coupling reactions is discussed here in this article. |

Environmental Catalysts for Complete Oxidation of Volatile Organic Compounds and Methane |
|
Nobuhito Imanaka, Toshiyuki Masui, and Keisuke Yasuda |
| [Full Text PDF(J-STAGE)] |
 |
| The present review describes novel oxidation catalysts developed in the group of the authors. These catalysts can completely oxidize volatile organic compounds (VOCs) and methane at moderate temperatures. A new concept based on the design of solid electrolytes has been applied to the preparation of the catalysts. |

Dual Activation in N-Heterocyclic Carbene-organocatalysis |
|
Keiichi Hirano, Isabel Piel, and Frank Glorius |
| [Full Text PDF(J-STAGE)] |
 |
| N-Heterocyclic carbene (NHC)-catalyzed transformations have found increasing interest in the last years. Recently, dual catalytic approaches using NHC in combination with a second catalyst such as another organocatalyst or a metal-based catalyst or by the NHC itself have emerged. The careful choice of the proper combination of the catalysts allows two compatible yet independent catalytic systems in one-pot to undergo tandem processes. Moreover, simultaneous action of two activators in a bond-forming event enables new reactivity and selectivity, which often cannot be achieved by monocatalytic approaches. |

Tetrathiafulvalene-based Cruciform Molecules |
|
Karsten Jennum and Mogens Brøndsted Nielsen |
| [Full Text PDF(J-STAGE)] |
 |
| Here we highlight our design and synthesis of cruciform molecules incorporating the redox-active unit tetrathiafulvalene (TTF) placed vertically to an oligo(phenyleneethynylene) (OPE) unit. These molecules have potential as redox-controlled wires (transistors) for molecular electronics. |

Photoalignment and Photoinduced Molecular Reorientation of Photosensitive Materials |
|
Nobuhiro Kawatsuki |
| [Full Text PDF(J-STAGE)] |
 |
| Linearly polarized (LP) light exposure to photosensitive materials containing azobenzene or photocrosslinkable groups generates photoinduced optical anisotropy as a result of axis-selective photoreaction. The resulting photoreacted thin films are useful for the alignment layer for functional materials. Furthermore, large optical anisotropy can be induced when the axis-selective photoreaction is accompanied by the molecular reorientation. |

Organic Charge-transfer Salts and the Component Molecules in Organic Transistors |
|
Takehiko Mori |
| [Full Text PDF(J-STAGE)] |
 |
| Electron donors and acceptors such as tetrathiafulvalene (TTF) and tetracyanoquinodimethane (TCNQ), which have been long known as components of organic metals, act as p- and n-channel organic semiconductors in organic field-effect transistors. High performance, good thin-film properties, and long-term stability have been achieved on the basis of appropriate molecular design. In addition, their charge-transfer complexes work as the active layers as well as the conducting electrode materials showing low contact resistance. |

Renaissance of Organic Synthesis Using Isocyanides |
|
Mamoru Tobisu and Naoto Chatani |
| [Full Text PDF(J-STAGE)] |
 |
| New reactions using old functionality, isocyanides, are described. By using isocyanides in place of carbon monoxide, transformations otherwise difficult to achieve, such as GaCl3-catalyzed [4 + 1] cycloaddition and TfOH-catalyzed insertion into a C–O bond of acetals, are realized. In addition, isocyanides are exploited as a key component in transition-metal-catalyzed C–H bond activation and borylation reactions. |

Organic Radical Battery Approaching Practical Use |
|
Kentaro Nakahara, Kenichi Oyaizu, and Hiroyuki Nishide |
| [Full Text PDF(J-STAGE)] |
 |
| The electrochemical redox reactions of organic polymers bearing robust unpaired electrons were investigated to determine the applicability of these polymers to rechargeable batteries. Such an “organic radical battery” would be environmentally friendly and have high-power characteristics. This highlight review describes the performances of the battery using a nitroxyl radical polymer as the cathode active material. The electron-transfer mechanism and recent developments that should lead to the practical application of the organic radical battery are also described. |

The Versatile Chemistry of Disilenides: Disila Analogues of Vinyl Anions as Synthons in Low-valent Silicon Chemistry |
|
David Scheschkewitz |
| [Full Text PDF(J-STAGE)] |
 |
| Disilenides can be used to introduce the Si=Si unit to a variety of organic and inorganic substrates, the Si=Si bond is either retained or undergoes further transformations. Heteroatom-substituted disilenes are easily accessible via disilenides. A variety of otherwise inaccessible compounds can be prepared: conjugated systems with more than one Si=Si unit, η1-transition-metal complexes, functional homo- and heteronuclear silacycles, and molecular silicon clusters with substituent-free vertices. |

How to Construct Chiral Macrocycles from Anthracene Units and Acetylene Linkers |
|
Shinji Toyota |
| [Full Text PDF(J-STAGE)] |
 |
| We propose strategies to construct chiral macrocycles by modification of the fundamental compound, 1,8-anthrylene–ethynylene cyclic tetramer. The enantiomers of some chiral derivatives could be resolved by chiral HPLC. The structures, dynamic behavior, and chiroptical properties of these macrocycles are summarized. |
