EXTRINSIC PHOTOCONDUCTION IN METALLOPORPHYRIN FILMS
Authors: Yamashita Kazuo , Maenobe Kuniharu , Fajer Jack 
Published: July 2006

Abstract
The dc photoconductance in films of metalloporphyrins has been explained by a mechanism which involves singlet exciton states followed by the interaction of these excitons with aluminum and surface impurity sites. The defect model of exponential trap distribution is useful to interpret the sublinear light dependence of the photocurrent, which is difficult to understand on the basis of exciton mechanism.

UPFIELD SHIFT OF CMR OF ANOMERIC CARBONS OF 1,1′-LINKED GLYCOPYRANOSYL GLYCOPYRANOSIDES
Authors: Koto Shinkiti , Inada Shigeru , Zen Shonosuke 
Published: July 2006

Abstract
Unusual upfield shifts are observed in CMR of anomeric carbons of α,α- and β,β-forms of 1,1′-linked d-glycopyranosyl d-glycopyranosides. On the contrary, α,β-forms of 1,1′-linked d-glycopyranosyl l-glycopyranosides show such upfield shifts. Possible cause of upfield shift is postulated in relation to the conformation of the glycoside linkage of 1,1′-linked glycopyranosyl glycopyranosides.
CONCERTED FRAGMENTATION CONCURRENT WITH A STEPWISE-DIRADICAL FISSION IN THE OXETANE THERMOLYSIS; IMPORTANCE OF STERIC STRAIN
Authors: Imai Toshiro , Nishida Shinya 
Published: July 2006

Abstract
Thermolytic behavior of 3-alkyl-2-phenyloxetanes, in particular that of trans isomers, is best explained by concurrent concerted fragmentation and stepwise diradical fission. Proportion of the concerted process should be small in the cis isomers because of destabilization of the transition state by steric strain. The argument is supported by the thermal behavior of 3-alkyl-4-phenyl-2-oxetanones.

OXYGEN REDUCTION ON GLASSY CARBON ELECTRODE MODIFIED BY POLYMER AND COBALT PHTHALOCYANINE
Authors: Kikuchi Takeyuki , Sasaki Hideo , Toshima Shinobu 
Published: July 2006

Abstract
Catalytic activities and the lifetime of chemically modified glassy carbon electrode by polystyrene(PS) and cobalt phthalocyanine(CoPC) were investigated in the reduction of oxygen by the measurements of current-potential curves in 6N KOH aqueous solutions. The PS coated electrode behaved in the same manner as the glassy carbon electrode without treatment (GCE), without any obvious current decrease and potential shift of the wave. The electrode coated with the PS containing the CoPC showed higher catalytic activities than the GCE during a long continuous operation, which had a longer life than the electrodes on which the CoPC was directly attached by the adsorption or the chemical modification.

Palladium(0) catalyzed alkenylation of 3′- or 4′-iodo- (or bromo-) benzocrown ethers are found to be a convenient procedure for the introduction of alkenyl groups (–CH=CH–R; R=Ph, COOEt and COOH). Iodination at 3′-position of benzocrown ethers could be achieved in good yield by the use of 4′-t-butyl derivatives.

A HIGHLY SELECTIVE AND RAPID SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF IRON(II) WITH 4-(2-THIAZOLYLAZO)RESORCINOL
Authors: Ueda Kazumasa , Yamamoto Yoshikazu 
Published: July 2006

Abstract
4-(2-Thiazolylazo)resorcinol reacts sensitively with iron(II) to form a water-soluble brown complex, which spectrally has the selective absorption at 730 nm.

X-RAY PHOTOELECTRON SPECTROSCOPIC STUDY OF THE SURFACE OF CARBON DOPED WITH POTASSIUM CARBONATE
Authors: Yokoyama Shin-ya , Tanaka Ken-ichi , Toyoshima Isamu , Miyahara Koshiro , Yoshida Kiyohide , Tashiro Jo 
Published: July 2006

Abstract
The X-ray photoelectron spectra of K and O peaks of the carbon impregnated with potassium carbonate were dramatically decreased by evacuation at 650 °C. When oxygen was introduced onto this surface, remarkable growth of these peaks was observed at room temperature, however, in case of contact with carbon dioxide, temperature as high as 650 °C was required to cause the same effect. These results support the reaction mechanism of a redox cycle of catalyst for the reduction of carbon dioxide with carbon.
DYNAMIC NMR AS A NONDESTRUCTIVE METHOD FOR THE DETERMINATION OF RATES OF DISSOCIATION. SCOPE OF THE METHOD AS APPLIED TO THE IONIC DISSOCIATION OF α-CHLORODIBENZYL SULFIDE
Authors: Oki Michinori , Shimizu Atsushi , Kihara Hiroshi , Nakamura Nobuo 
Published: July 2006

Abstract
Dynamic NMR technique was applied to the determination of the rates of ionic dissociation of α-chlorodibenzyl sulfide in chloroform-d. Total line shape analysis afforded ΔH≠ 28 kJ mol−1 and ΔS≠ −120 J K−1 mol−1 which were not dependent on the concentration of the substrate. The results imply that the initial steps of SNl reactions can be studied by the method. Scope of the method is discussed.
ON THE REVERSIBILITY OF METAL CARBENE FORMATION PROCESS IN OLEFIN METATHESIS REACTION OVER MoOx /β-TiO2 CATALYST
Authors: Tanaka Katsumi , Miyahara Koshiro , Tanaka Ken-ichi 
Published: July 2006

Abstract
Co-isomerization of d0- and d8-cis-2-butene was carried out on a novel catalyst, MoOx/β-TiO2(2.9&gt;x&gt;2.3), which is active for olefin metathesis reaction without inter- and intra-molecular hydrogen scrambling of olefins. The ratio, d4/(d0+d8), in produced trans-2-butene was found to be zero at the initial stage of the reaction, indicating a type of cis–trans isomerization by intra-molecular metathesis.

STRUCTURE OF TYRIVERDIN, THE IMMEDIATE PRECURSOR OF TYRIAN PURPLE
Authors: Fujise Yutaka , Mlwa Katsuyuki , Itô Shô 
Published: July 2006

Abstract
Stereoisomeric tyriverdins A and B were isolated from Thais clavigera. The former, which is identical with tyriverdin isolated by Baker, was confirmed by 13C-NMR spectrum to be 2,2′-bis(methylthio)-6,6′-dibromo-2,2′-diindoxyl . None of these compounds are detected in the gastropod, suggesting that they are formed during the isolation process probably from tyrindoxyl sulfate, a genuine constituent.

Authors: Inoue Hiroyasu , Mori Tsunehisa , Sakurai Tadamitsu 
Published: July 2006

Abstract
Benzil shows dual phosphorescence in an ethylene glycol glass at 77 K. The short-lived phosphorescence at 504 nm is assigned to near-planar transoid geometry. Evidence indicates that the long-lived one appearing three maxima at 402 nm, 427 nm, and 460 nm is due to medium imposed near-planar cisoid geometry.

Abstract
Oxidation of 4-allylphenols in MeOH has been carried out using thallium (III) nitrate to give two different types of reaction product. In the cases of 4-allylphenols with an electron-donating group (MeO), methoxylation takes place on the aromatic ring resulting in the formation of asatone-type compound as well as of 2,5-cyclohexadien-1-one. In the case of 4-allyl-2-methoxy-6-nitrophenol, however, the allyl group was attacked by the reagent to give three phenols.
