Authors: Inokuchi Hiroo , Saito Gunzi , Wu Peiji , Seki Kazuhiko , Tang Tong Bor , Mori Takehiko , Imaeda Kenichi , Enoki Toshiaki , Higuchi Yoshiki , Inaka Koji , Yasuoka Noritake 
Published: July 2006

Abstract
The electrical conductivity of alkylthio-substituted tetrathiafulvalene (TTCn-TTF) single crystal has been measured in a vacuum of 10−4 Pa with the two probe method. The room temperature dark conductivity of TTC10-TTF reaches 10−5 S cm−1, a value that is extraordinarily high compared with those of other organic semiconductors constructed with a single component. The cause of this high conductivity is that the central tetrathiafulvalene skeleton has been fastened strongly with the four long alkyl chains.

The Redox Potential of a Synthetic Fe4S4 Cluster. Protonation/Deprotonation Equilibria of the Oxidized and Reduced Species
Authors: Masanaga Mari , Kuwabata Susumu , Tanaka Koji , Tanaka Toshio 
Published: July 2006

Abstract
The redox potential of [Fe4S4(S-p-C6H4C8H17n)4]2− in an aqueous poly-α-dimethylamino-ε-capramide solution is shifted by −55 mV/pH in the pH range 6.0 to 8.5 at 4 °C, suggesting that not only the oxidized but also reduced forms of the cluster undergo protonation/deprotonation equilibria. The spread of the redox potential of the cluster in the present study covers most of the redox potentials of 4-Fe ferredoxins reported so far.
Behavior Characteristic of (η5-Cyclopentadienyl)(1,2-di-2-pyridyl-1,2-ethylenedithiolato)cobalt(III) and Its Diselenolato Analog. Elimination of 2S or 2Se and Exchange of S and Se
Authors: Kajitani Masatsugu , Ito Mari , Kobayashi Norikazu , Akiyama Takeo , Sugimori Akira 
Published: July 2006

Abstract
(η5-Cyclopentadienyl)(1,2-di-2-pyridyl-1,2-ethylendithiolato)cobalt(III) (1) and its selenium analog (2) show interesting reactivities at the S and Se moiety. A characteristic peak in MS of 1 and 2 measured using a direct inlet system under heating is found at m/z=304 assigned to ((M-2S)+ or (M-2Se)+). The reflux of 2 in toluene with S8 causes the exchange of Se by S in the complex.

Authors: Takahashi Osamu , Saka Takahiro , Mikami Koichi , Nakai Takeshi 
Published: July 2006

Abstract
The lithium ester and ketone enolates (generated in HMPA-THF) and the dilithiated oxime (generated in THF) are shown to serve well as the migrating terminus for the [2,3]Wittig shift, not for the [3,3]Claisen shift. On the basis of these observations, the solution structures of the “lithium enolates” are discussed.

Triphenylantimony dicarboxylates (Ph3Sb(O2CR)2, where R=Me, CF3, Ph and CH2NH-Z) readily reacted with amines (R′NH2, where R′=n-C6H13, s-Bu, C6H11, and Ph) to afford corresponding amides and triphenylstibine oxide in fairly good yields. The amidation of RCO2H with R′NH2 was also catalyzed by the orgnoantimony compounds.

On the other hand, the Co(III) species electrogenerated similarly showed only limited catalytic activity.
TRICHLOROLANTHANOID(LnCl3)-CATALYZED FRIEDEL–CRAFTS ALKYLATION REACTIONS
Authors: Mine Norioki , Fujiwara Yuzo , Taniguchi Hiroshi 
Published: July 2006

Abstract
The usual Friedel–Crafts catalysts cannot be re-used after aqueous work-up. An alternative catalyst, based on rare earths has been found, which serves as an efficient Friedel–Crafts catalyst for alkylation of arenes by alkyl halides, and can be re-used after the reaction. Typical examples are shown in the reaction of benzene with benzyl halides using all of the rare earth trichlorides as catalyst, except PmCl3.

Authors: Arakawa Tsuyoshi , Takada Ken-ichi , Tsunemine Yoshikazu , Shiokawa Jiro 
Published: July 2006

Abstract
The detection of CO gas was studied using LaCoO3−x as a sensing material which was obtained by reduction of LaCoO3 in a hydrogen atmosphere at 500 °C. LaCoO3−x exhibits the change of the resistivity at low temperatures in the presence of hydrogen and has a sensitivity-temperature profile with a maximum at about 100 °C. CO adsorption causes a decrease in the resistivity of LaCoO3−x as in the case of O2 adsorption although LaCoO3−x is a p-type semiconductor.
THE CRYSTAL STRUCTURE OF β′-(BEDT-TTF)2ICl2. A MODIFICATION OF THE ORGANIC SUPERCONDUCTOR, β-(BEDT-TTF)2I3
Authors: Kobayashi Hayao , Kato Reizo , Kobayashi Akiko , Saito Gunzi , Tokumoto Madoka , Anzai Hiroyuki , Ishiguro Takehiko 
Published: July 2006

Abstract
The crystal of β′-(BEDT-TTF)2ICl2 has a modified structure of organic superconductor, β-(BEDT-TTF)2I3. Unlike the β-type salt with a two-dimensional(2D) electronic structure, the anisotropy of the intermolecular overlap integrals of HOMO of BEDT-TTF in β′-(BEDT-TTF )2ICl2 suggests the 1D character of the electronic structure.

The faradaic efficiency of CH4 formation was about 65% at 0 °C and dropped with an increase of temperature, whereas that of C2H4 formation rose to ca. 20% at 40 °C.
STRIKINGLY HIGH PHOTOVOLTAGES OF PHOTOELECTROCHEMICAL SOLAR CELLS EQUIPPED WITH PLATINUM-COATED AND ALKALI-ETCHED n-Si ELECTRODES
Authors: Nakato Yoshihiro , Yano Hiroyuki , Tsubomura Hiroshi 
Published: July 2006

Abstract
Open-circuit photovoltages (Voc) of photoelectrochemical cells having an n-Si electrode coated with vacuum-evaporated platinum in an aqueous redox solution have been remarkably increased by etching the Pt-coated n-Si electrode in alkaline solutions. The maximum Voc obtained was 0.685 V, about 15% higher than that of normal p-n junction Si solar cells (0.59 V), demonstrating the possibility of using these cells as highly efficient solar energy converter. The large increase in Voc is explained by a theory recently proposed by us on semiconductor electrodes coated with microscopically discontinuous metal layers.

Furthermore, the one that is represented by Eq.2 permits complete control of regiochemistry as well.

Published: July 2006

Abstract
3-Cyclodextrin (CD), as well as γ-CD, enhances dimerization of some cyanine dyes, as revealed by the enhancement of dimer band in absorption spectra. The presence and absence of enhancement are governed by geometrical factors, i.e., the length of central methine chain and the size of the chromophore at each end.

Published: July 2006

Abstract
The photoreaction of 5-bromo-1,3-dimethyluracil in 1,4-xylene solution yields a mixture of 5- and 6-aryl substituted uracils. The 5-isomer is formed first and is followed by the 6-isomer, the latter being the product from protonated uracil. In the presence of initially added acid (HBr and trifluoroacetic acid) both isomers are formed simultaneously.

Authors: Jintoku Tetsuro , Taniguchi Hiroshi , Fujiwara Yuzo 
Published: July 2006

Abstract
Benzene reacts with O2 (15 bar) to give phenol directly in a high yield via the direct phenyl C–H bond activation promoted by some Pd based catalysts/CO(15 bar)/1,10-phenanthroline systems. Addition of both CO (15 bar) and phenanthroline or bipyridine is needed for the selective synthesis of phenol. Benzene also reacts with H2O to give phenol by the catalysis of a 5% Pd–C catalyst.

Abstract
The Arbuzov reaction of (5S,6S)-dimethoxy-2-phenyl-1,3,2-dioxaphosphacycloheptane with various alkyl halides produced acyclic phosphinates in a moderate to high diastereomer excess. The same reaction of (1S,7S)-9,9-dimethyl-4-phenyl-3,5,8,10,4-tetraoxaphosphabicyclo[5.3.0]decane with the alkyl halides needed the more vigorous reaction conditions and gave phosphinates in a low diastereomer excess. These phosphinates were converted into optically active phosphine oxides.
