Authors: Shiromaru Haruo , Takeshita Kouichi , Katsumata Shunji 
Published: July 2006

Abstract
The magnitude of the Jahn–Teller splitting of the 2T2 ionic state of methane was successfully calculated without determining the potential surface of the ionic state. This method can be easily applied to analyses of Jahn-Teller splittings observed in photoelectron spectroscopy.

SEPARATION AND CHARACTERIZATION OF TWO COBALT(III) DIASTEREOMERS DUE TO CHIRAL O-BONDED SULFINATE
Authors: Yamahari Kazuaki , Shimura Yoichi 
Published: July 2006

Abstract
Two diastereomers due to the chiral O-bonded sulfinate in Λ-[Co(NH2CH2CH2SO2-N,O)(en)2](ClO4)2 were separated and characterized by the visible-UV absorption, circular dichroism(CD), and 13C NMR spectra. The absolute configurations were determined by comparison of the CD spectra with that of the corresponding O-bonded Λ-R-seleninato complex. The racemization of the chiral sulfinato moiety proceeded at a relatively slow rate, which is responsible for the successful separation of the diastereomers.

REGIOSELECTIVE FUNCTIONALIZATION OF cis-BICYCLO|3.3.0|OCTENONE DERIVATIVES. OXYMERCURATION/REDUCTION versus HYDROBORATION/OXIDATION. ACETAL GROUPS AS REGIO- AND STEREOSELECTIVE CONTROL ELEMENTS
Authors: Carceller Elena , Castelló Assumpta , García M Lluísa , Moyano Albert , Serratosa Félix 
Published: July 2006

Abstract
Cyclic acetal groups at the position 8 of the cis-bicyclo|3.3.0|octane system may act as regio- and stereoselective control elements, respectively, in hydroboration and oxymercuration reactions. Whereas the regioselectivity observed in hydroborations must be ascribed to homoallylic inductive effects, and leads predominantly to exo, 1,3-bifunctional relationships, the effect of acetal group in oxymercuration is mainly stereoselective due to coordination of mercury acetate with the nonbonding electron pairs of the endo-oxygen atom of the acetal group, and leads predominantly to exo, 1,4-bifunctional relationships.

Published: July 2006

Abstract
Treatment of Ru(CH3)I(1-3:6-7:10-12-η-C12H18) with CO, tBuNC, or phosphites facilitates reductive coupling of the methyl group and the π-allyl moiety to give Ru(II) complexes, RuIL3(1-3-η-C13H21) [L=CO, tBuNC,P(OR)3]. Addition of one equivalent of tBuNC leads to selctive formation of Ru(tBuNC)I(1-3:6-7:11-12-η-C13H21).

Authors: Ishikawa Yuji , Tajima Kunihiko , Mukai Kazuo , Ochi Osamu , Ishizu Kazuhiko , Sakurai Hiromu 
Published: July 2006

Abstract
An Egg-Yolk lecithin liposome containing the surfacant cyclic polyamine was prepared, and a dynamical behavior of its Cu(II) ion uptake was studied by monitoring a time dependent decay of the isotropic copper nucleus hyperfine splitting in the ESR upon metal incorporation into a liposomal membrane. The reaction kinetics studied by ESR justified the fact that there are the two kinds of metal binding processes, in which the distinctive time course and the activation energy can be clearly demonstrated.

Abstract
It was found that amidines were obtained directly by the reaction of carboxylic acids with amines in the presence of PPSE, and the yields of amidines were dependent on the structure of amines rather than that of carboxylic acids.

Authors: Kotake Yashige , Kuwata Keiji 
Published: July 2006

The result was compared with that of NMR in the concentrated solution of the radicals. The magnitude of hyperfine splitting constants is shown to be very sensitive to the structure of the radical.

Authors: Shimidzu Naoki , Masuda Hideki , Ohno Shin 
Published: July 2006

Abstract
The surface chemical properties of cuprous-iodide (CuI) film evaporated on a polymer layer containing a precursor reducing agent, 2-isopropoxy-1,4-naphthoquinone (IPNQ), were markedly affected by UV irradiation. The CuI was reduced by photoproducts of the IPNQ and the surface reductants attracted the zinc vapor in a vacuum evaporation vessel. Thus the UV exposure resulted in the zinc vapor deposition.
CONDUCTION ELECTRON SPIN RESONANCE OF ULTRAFINE PARTICLES OF MAGNESIUM
Authors: Kimura Keisaku , Sako Sanshiro 
Published: July 2006

Abstract
Two resonance lines were observed in the conduction electron spin resonance of ultrafine particles of magnesium prepared in tetrahydrofuran. From the microwave frequency and the power dependencies of the resonance lines, it was found that the broader line was attributed to the quantum size effect which appears only in small particles, whereas the narrower line was due to a surface impurity.

In the crystal of (BMDT-TTF)3PF6(1,2-dichloroethane) (BMDT-TTF= bis(methylenedithio)-tetrathiafulvalene), there are two crystallographically independent BMDT-TTF molecules whose molecular planes are approximately perpendicular to each other. This new type of molecular arrangement achieves the two-dimensional S···S network.
HOST-GUEST-TYPE ACID CATALYSTS DERIVED FROM CALIX[6]ARENE
Authors: Shinkai Seiji , Koreishi Hiroshi , Mori Seiichi , Sone Takaaki , Manabe Osamu 
Published: July 2006

Abstract
Water-soluble calix[6]arenes bearing both acidic protons and sulfonate groups were synthesized. They catalyzed a hydration reaction of 1-benzyl-1,4-dihydronicotinamide (BNAH) according to Michaelis-Menten kineticts and the rate constants were greater by 426–1220 fold than those for noncyclic analogues. Fluorescence data supported the complexation of BNAH with these water-soluble calixarenes. These findings indicate that calixarenes serve as a new starting material to design functionalized host molecules.

The enolate further reacts with aldehyde to afford the aldol product with high syn-stereoselectivity. The aldol product thus produced is stereospecifically converted to β-lactam derivative with hydroxyethyl side chain.

Authors: Tomioka Hideo , Tabayashi Kazuo , Izawa Yasuji 
Published: July 2006

Abstract
The carbene generated by photolysis of sodium α-diazoacetate in a binary mixture of methanol and 2-methyl-2-butene showed 3 000 times enhanced reactivity toward methanol relative to the alkene compared to that derived from the corresponding ester or acid. The results are interpreted as indicating that the neighboring carboxylate group interacts with electron-deficient center of carbene.

Authors: Kurosawa Hideo , Emoto Mitsuhiro 
Published: July 2006

Abstract
Kinetic studies on reductive elimination of η3-allyl(aryl)–palladium(II) complexes suggest lack of ligand dissociation prior to the C–C coupling. On the contrary, the fourth ligand which remains coordinated plays an important role, by virtue of its electronic effect, in determining the barrier to the C–C coupling.

Abstract
3,3,6,6-tetraaryl-1,2,4,5-dioxadithianes, containing a new heterocycle, are isolated and characterized as reaction intermediates in thiocarbonyls to carbonyls transformations using clay supported metal nitrates. We propose a plausible mechanism, explaining the nitrosating behaviour of the reagent in this process.

Published: July 2006

Abstract
Photolysis of N-methylphenanthrene-9,10-dicarboximide (PI) with diethylamine (1a) in benzene gave an aminolysis product together with reduction-products and other coupling products. Effects of addition of 1-propanethiol and concentration of 1a indicate that the aminolysis appears to arise from N–H abstraction mainly by excited triplet state of PI.

Chloroplatinic acid in an aqueous solution was reduced by hydrogen molecules or photo-irradiation in the presence of surfactants to produce colloidal dispersions of platinum protected by the surfactants. The particles of the colloidal platinum prepared by photo-reduction were smaller in size and more narrowly dispersed than those prepared by hydrogen-reduction. They worked as highly active catalysts for hydrogenation of olefins.

Published: July 2006

Abstract
We report the first model of electrically activated mechanochemical system made of polyelectrolyte gels which contracts, oscillates, and bends reversibly. On the basis of this principle a variety of devices which function under electric stimulus, i.e., a “chemical valve” membrane expanding and contracting the pore size, a switching oscillating 15 to 100 times per minute, and a composite bending like “bimetal” were developed.
