THE CRYSTAL AND ELECTRONIC STRUCTURES OF BEDT-TTF2I2Br
Authors: Kobayashi Hayao , Kato Reizo , Kobayashi Akiko , Saito Gunzi , Tokumoto Madoka , Anzai Hiroyuki , Ishiguro Takehiko 
Published: July 2006

Abstract
The crystal structure of BEDT-TTF2I2Br is isomorphous to the well-known superconductor, β-BEDT-TTF2I3. The suppression of the superconductivity in BEDT-TTF2I2Br down to at least 0.5 K, will be ascribed to the orientational disorder of the I2Br anions. Examination of the intermolecular overlap integrals indicates that the system has a two-dimensional closed Fermi surface.
SELECTIVE SYNTHESIS OF C2-OXYGENATES BY CO HYDROGENATION OVER SILICA-SUPPORTED Co–Ir CATALYST
Authors: Kintaichi Yoshiaki , Kuwahara Yasushi , Hamada Hideaki , Ito Takehiko , Wakabayashi Katsuhiko 
Published: July 2006

Abstract
Silica-supported Co–Ir bimetallic catalyst was effective for the selective synthesis of C2-oxygenates such as ethanol, acetaldehyde, and acetic acid by vapor-phase CO hydrogenation at 280–320 °C and 51 atm. It is suggested that Co–Ir catalyst may form an active species responsible for the synthesis of C2-oxygenates.
THE ENHANCED FORMATION OF C2-OXYGENATES IN THE HYDROGENATION OF CARBON MONOXIDE OVER THE MODIFIED COBALT CATALYSTS
Authors: Sugi Yoshihiro , Takeuchi Kazuhiko , Matsuzaki Takehiko , Arakawa Hironori 
Published: July 2006

Abstract
The formation of C2-oxygenates was enhanced by the modification of Co/SiO2 catalyst, prepared from cobalt(II) acetate, with transition metal (Ru or Re) and alkaline earth in the hydrogenation of carbon monoxide. The X-ray photoelectron spectra suggest that the cobalt is kept in the moderate oxidation state by synergetic effects of transition metal and alkaline earth. The formation of C2–O occurrs on the partly reduced cobalt site.

C–C BOND FORMATION BY THE PHOTOINDUCED REACTIONS OF cis-DIALKYLCOBALT(III) COMPLEXES WITH BENZYL AND ALLYL BROMIDES
Authors: Fukuzumi Shunichi , Ishikawa Kunio , Tanaka Toshio 
Published: July 2006

Abstract
The photocleavage of cobalt-carbon bonds of cis-dialkylcobalt(III) complexes, cis-[R2Co(bpy)2]ClO4 (R = Me, Et, and PhCH2; bpy = 2,2′-bipyridine), induces the selective C–C bond formation from benzyl and allyl bromides to yield 1,2-diphenylethane and 1,5-hexadiene, respectively. The monoalkylcobalt(II) complexes [RCo(bpy)2]+ formed by the photocleavage reactions are responsible for the selective reduction of benzyl and allyl bromides.

Abstract
Asymmetric reduction of prochiral α- and β-hydroxy ketones with a reagent, generated from tin(II) chloride, a chiral diamine, and diisobutylaluminum hydride, afforded the corresponding dihydroxy compounds in good chemical and optical yields. Optical yields depended on the nature of the protective groups of hydroxyl function.

Authors: Yagihara Shin , Nozaki Ryusuke , Mashimo Satoru , Higasi Ken-iti 
Published: July 2006

Abstract
Dielectric relaxation times of 1-propanol were measured in 1,4-dioxane and cyclohexane at 25 °C by the TDR method. Dielectric behavior of this alcohol varied greatly according to the nature of the solvent. A single relaxation process was observed when the hydrogen bonding solvent was employed, while two separate relaxation processes were found in the inert solvent.
SPECTROPHOTOMETRIC DETERMINATION OF PARTS PER BILLION LEVEL PHOSPHATE BY “STOPPED-FLOW TIME DIFFERENCE ANALYSIS” USING MALACHITE GREEN AND MOLYBDATE
Authors: Kanaya Ken-ichiro , Hiromi Keitaro 
Published: July 2006

Abstract
The “stopped-flow time difference analysis” method [K. Hiromi, C. Kuwamoto, and M. Ohnishi, Anal. Biochem., 101, 421 (1980)] was applied to the rapid and simple determination of trace amounts of phosphate, using Malachite Green and molybdate. The specific determination of phosphate down to the ppb level was successfully carried out even in the presence of 20 fold-excess (w/w) of AsO43−. The detection limit was as low as 2 ppb.

Authors: Tsuge Otohiko , Kanemasa Shuji , Matsuda Koyo 
Published: July 2006

Abstract
Through alkylation or silylation and then desilylation steps, N-(silylmethyl)amidines generate N-protonated azomethine ylides which cycloadd to olefins, acetylenes, and aldehydes giving 1- or 2-pyrrolines, pyrroles, and 2-oxazolines, respectively, after the elimination of N-substituted anilines. With this sequence, the amidines are useful synthetic equivalents of nonstabilized nitrile ylides.
PRELIMINARY TREATMENT WITH AMMONIA IN REDUCTION OF CuY ZEOLITE
Authors: Tanabe Shuji , Matsumoto Hiroshige 
Published: July 2006

Abstract
The reduction process of CuY zeolite has been investigated in temperature programmed experiments. The reduction of Cu2+ ions with H2 occurred by a two-step mechanism, via Cu+ ions to Cu metal. In the first step of reduction NH3 was used as the reducing agent instead of H2. Copper particles in the reduced zeolite with the NH3-pretreatment were uniformly dispersed compared to those without the NH3-pretreatment. The average diameters of the particles were estimated to be 8.4 nm for the former and 18.5 nm for the latter.

The adsorbent adsorbs 15.0 mmol of ethylene at 20 °C, 1 atm, which is 7.9 fold larger than the value (1.9 mmol) for ethane.
CYCLODEXTRIN-CATALYZED HYDROLYSIS OF ESTERS BEARING A HYDROPHOBIC TAIL
Authors: Ueno Akihiko , Suzuki Iwao , Hino Yoshihiro , Suzuki Atsuko , Osa Tetsuo 
Published: July 2006

Abstract
γ-Cyclodextrin-catalyzed hydrolysis of p-nitrophenyl esters bearing a long alkyl chain proceeded with larger rate acceleration than those with a short alkyl chain. Such rate acceleration behavior was not observed with β-cyclodextrin. The results suggest that the esters with a long alkyl chain take a folded structure (Type A) in the γ-cyclodextrin cavity.

Authors: Suzuki Hitomi , Manabe Hajime , Inouye Masahiko 
Published: July 2006

Abstract
Sodium telluride, prepared by heating tellurium with Rongalite in aqueous sodium hydroxide, easily reduces aromatic nitro compounds to the corresponding amines in good yields. The reduction can be carried out using a catalytic amount of tellurium, since sodium telluride is readily regenerated in the presence of excess Rongalite.

ELECTROCHEMICAL BEHAVIORS OF CYCLOPOLYSILANES. OXIDATION POTENTIALS VIA CYCLIC VOLTAMMETRY
Authors: Watanabe Hamao , Yoshizumi Koichi , Muraoka Tsutomu , Kato Motohiko , Nagai Yoichiro , Sato Takeo 
Published: July 2006

Abstract
The anodic peak potentials for a series of cyclopolysilanes, [R1R2Si]n (n=3–7), lowered with decreasing ring size and were found to be parallel to the lowest transition energies determined by the UV absorptions. In the anodic oxidation these cyclopolysilanes undergo the initial one electron transfer reaction to give a cation radical which leads to the formation of an acyclic α,ω-radical cation followed by the second electron transfer to give the corresponding di-cation.

Published: July 2006

Abstract
2-Substituted tropones reacted with Fe2(CO)9 or with Fe(CO)5 under irradiation to give iron tricarbonyl complexes coordinated at unsubstituted diene moiety. 2-Bromotropone afforded another iron tricarbonyl complex coordinated at substituted diene as a minor product. 2-Methyl-, 2-phenyl-, and 2-tosyloxytropones yielded di-π-allyl type diiron hexacarbonyl complexes. Furthermore, 2-dialkylaminotropones gave diiron hexacarbonyl complexes as a major product containing a new enamine type complex.
