Authors: Oku Akira , Kimura Kenji , Sato Masaya 
Published: July 2006

Abstract
All halogen atoms in 1,1,2-trichloro-1,2,2-trifluoroethane (F-113) were removed in the form of chloride and fluoride ions by the treatment with sodium naphthalenide (1.5 equiv. per halogen atom) in THF at 150 °C for 50 min in the presence of 10 vol% tetraethyleneglycol dimethylether. Similar treatment was also efficacious in the dehalogenation of F-22 and F-12.

Effect of Rh Dispersion on Vapor Phase and Pressurized Hydroformylation of Ethylene over Rh/SiO2 Catalyst
Authors: Arakawa Hironori , Takahashi Nobuo , Hanaoka Takaaki , Takeuchi Kazuhiko , Matsuzaki Takehiko , Sugi Yoshihiro 
Published: July 2006

Abstract
A significant Rh dispersion effect was observed on vapor phase and pressurized hydroformylation of ethylene over Rh/SiO2 catalyst. Hydroformylation proceeds favorably over a high dispersed Rh/SiO2 having Rh particle size below approximately 30 Å. This remarkable dispersion effect is attributed to the change of both surface Rh atom composition and electronic state of Rh particle on SiO2. In addition, a striking structure sensitivity was also observed on the hydrogenation of ethylene to ethane as a by-product.

Authors: Maezawa Akinori , Kane Hiroshige , Okamoto Yasuaki , Imanaka Toshinobu 
Published: July 2006

Abstract
The thermal stabilities of Mo(CO)6 and subcarbonyl species encaged in a zeolite were found to depend markedly on the Si/Al ratio and cation involved. A highly selective formation of cis-2-butene was observed for the hydrogenation of butadiene over the subcarbonyl species. These thermal and catalytic properties of the carbonyls are correlated to the basicity of the zeolite.

Authors: Yamamoto Takeshi , Shimoda Akihide , Okuhara Toshio , Misono Makoto 
Published: July 2006

Abstract
Copper supported on SiO2, which was prepared from Cu(OCOCH3)2 and to which P was added, was a selective catalyst (80–85% at about 50% conversion) for the formation of HCHO by the dehydrogenation of CH3OH at 500 °C. Among various additives such as P, B, K, Li, Mo, and Zn, the addition of P to the Cu/SiO2 significantly enhanced the rate for the formation of HCHO with an increase in the selectivity.
Selective Dehydrogenation of Alkylamines to Nitriles over Metal Oxide Catalysts
Authors: Xu Bo-Qing , Yamaguchi Tsutomu , Tanabe Kozo 
Published: July 2006

Abstract
Decomposition of alkylamines over ZrO2, SiO2–Al2O3, and MgO were examined in a closed recirculation reactor. ZrO2 showed the highest activities and selectivities for the formation of nitriles, especially in di- and trialkylamine decomposition. In contrast, SiO2–Al2O3 catalyzed dealkylation and deamination reactions exclusively. MgO exhibited high selectivity for the dehydrogenation of primary alkylamine. The high activity of ZrO2 is attributed to its acid-base bifunctional properties.

Abstract
The crystal structures of an organic superconductor (BEDT-TTF)2Cu(NCS)2 (Tc=10.4 K) at 298 K and 104 K are determined by X-ray analysis. The packing pattern of donors is nearly analogous to κ-(BEDT-TTF)2I3. The counter anion, Cu(NCS)2−, has no positional disorder and constructs a peculiar sheet where a copper ion is coordinated with a sulfur and two nitrogen atoms to form a one-dimensional polymer with a permanent dipole moment.
