Authors: Katayama Chuji , Honda Masako , Kumagai Hiroaki , Tanaka Jiro , Saito Gunzi , Inokuchi Hiroo 
Published: July 2006

Abstract
Hexacyanobutadiene(HCBD) forms two kinds of molecular complexes with tetramethyltetrathiafulvalene(TMTTF) one kind with tetramethylthiotetrathiafulvalene(TTMTTF). The crystal structures of these complexes and neutral TTMTTF are determined by X-ray analyses. (TMTTF)2·HCBD is composed of 2:1 donor and acceptor, and TMTTF exists as a dimer cation stacked along the c axis. HCBD anions are included in the cavity of the dimer stack directing their molecular planes parallel to the stacking axis. TMTTF·HCBD is composed of 1:1 donor and acceptor, and has segregated cation and anion stacks with the interplanar spacing of 3.61 Å in TMTTF and 3.43 Å in HCBD columns. TTMTTF·HCBD is shown to have a regular segregated column with a partial charge transfer. Neutral TTMTTF has a non-planar conformation. The C=C and C–S bond lengths of the donors in free and complexed states are correlated with the degree of the charge transfer in these four complexes, and linear relationships are found between these two quantities.
Studies of “Manganese Cycle” for Gasification of Solid Carbon Resources. I. Formation and Hydrolysis of Manganese Carbides and Their Repetition
Authors: Iwahara Hiroyasu , Uchida Hiroyuki , Mizoguchi Satoshi 
Published: July 2006

Abstract
A new carbide method based on “Manganese Cycle” was studied in order to produce new fuel gas. This process consists of four steps; (i) carbide production from Mn2O3 and solid carbon sources, (ii) fuel gas production by means of hydrolysis of the carbide, (iii) spontaneous oxidation of Mn(OH)2 with air to Mn2O3, and (iv) regeneration of the carbide from Mn2O3 and new carbon sources. In this process, manganese is used as a recyclable medium for gas production, and hydrogen and hydrocarbons (C1–C5) are obtained by hydrolysis. Carbon monoxide generated during the formation of the carbide is also utilizable. The addition of Li2CO3 was effective for the carbide reproduction.
The Viscosities and Molal Volumes of t-Butyl Alcohol in Metal Chelate Electrolyte Solutions
Authors: Yoshitani Kouzou 
Published: July 2006

Abstract
The Viscosities and molal volumes of t-butyl alcohol (t-BuOH) in aqueous solutions of [Fe(phen)3]Cl2, [Co(phen)3]Cl3 (phen=1,10-phenanthroline), [Co(en)3]Cl3 (en=ethylenediamine), tetraphenylphosphonium chloride ((C6H5)4PCl), tetramethylammonium chloride (Me4NCl), tetraethylammonium chloride (Et4NCl), and tetra-n-butylammonium bromide ((n-Bu)4NBr) were measured at 25 °C, and solute–solvent interactions characteristic of the metal chelate cations were investigated. The apparent molal volumes of t-BuOH in the solutions of [Fe(phen)3]2+ are larger than those in the (n-Bu)4N+ and [Co(phen)3]3+ solutions. The hydrophobicity of [Fe(phen)3]2+ is not so strong because of the aromaticity of the ligand. The same can be said for [Co(phen)3]3+. However, on the interaction between [Co(phen)3]3+ and t-BuOH, the charge-dipole interaction and hydrophobic interaction act cooperatively to stabilize this pair through the overlap of the solvation spheres.
X-Ray Photoelectron Spectra and Electrical Conductivities of One-dimensional Halogen-bridged Pd(II)–Pt(IV) and Ni(II)–Pt(IV) Mixed-valence Complexes
Authors: Yamashita Masahiro , Murase Ichiro , Ito Tasuku , Wada Yoshiki , Mitani Tadaoki , Ikemoto Isao 
Published: July 2006

Abstract
The X-ray photoelectron spectra have been measured for the one-dimensional halogen-bridged metal-alternated mixed-valence complexes, [PdII(en)2][PtIVX2(en)2](ClO4)4 (X=Cl, Br, and I) and [NiII(en)2][PtIVX2(en)2](ClO4)4(X=Cl and Br), along with their parent complexes, [Pd(en)2]Cl2, Ni(en)2Cl2, and [PtCl2(en)2]Cl2. As the bridging halogen changes from Cl to I, the binding energies of the Pt(IV)4f levels become lower while those of M(II) (M=Pd and Ni) levels become higher, each gradually approaching to the M(III) binding energies (M=Pt, Pd, or Ni), respectively. Comparing the binding energies of the Pt(IV)4f levels in these hetero-metal mixedvalence complexes with those previously reported for the homo-metal halogen-bridged Pt(II)–Pt(IV) mixedvalence complexes having the same bridging halogens, the reductive trend of the oxidation states of Pt(IV) is found to be significantly suppressed by the metal alternation. In accord with this result, the activation energies obtained from the electrical conductivities are fairly larger than those of the homo-metal Pt(II)–Pt(IV) mixed-valence complexes. Their magnitudes are in the order of PdII–PtIV&gt;NiII–PtIV&gt;PtII–PtIV, suggesting that the electron–electron repulsion energy on M(II) ions plays an important role in mixed-valence states.
A Highly Selective Transannular Route to trans-trans-1,2,3,3a,4,-5,9,10,10a,10b-Decahydropyrenes from [2.2]Metacyclophanes
Authors: Sato Takeo , Nishiyama Kozaburo , Morita Akira , Iitaka Yoichi 
Published: July 2006

Abstract
The treatment of [2.2]metacyclophanes with aluminum chloride gave a variety of hydropyrenes as the results of dehydrogenation, cycloisomerization, and disproportionation reactions. With ethylaluminum dichloride, however, a highly selective reaction occurred to give trans-trans-1,2,3,3a,4,5,9,10,10a,10b-decahydropyrene. Revised structures were presented for cis-cis- and trans-trans-decahydropyrenes based on 13C NMR and X-ray crystallographic analyses.
Kinetics and Mechanisms of Oxidations by Metal Ions. V. Oxidation of 4-Oxopentanoic Acid by the Aquavanadium(V) Ion
Authors: Mehrotra Raj Narain 
Published: July 2006

Abstract
The outer sphere oxidation of 4-oxopentanoic acid(4-OPA), studied at 50 °C by aquavanadium(V) ion, is H+-catalyzed reaction. The reaction has a first-order dependence on each of [Vv], [4-OPA], and [H+]. The H+ catalysis can not be ascribed to keto\ightleftarrowsenol equilibrium because of the knowledge that a γ-keto acid is the least enolized amongst keto acids. Hence V(OH)32+ (aq) ion is the active oxidant. The proposed mechanism, assumed to involve the initial decarboxylation, is supported by the spot test characterization of acetoin as the intermediate oxidation product. Acetoin is further oxidized to two moles of acetic acid which is the final oxidation product. The overall energy of activation(ΔH1=26±3 kJ mol−1) is lower than the normal value(84 kJ mol−1) and therefore the highly negative value of the overall entropy of activation(ΔS1=−268±8 J K−1 mol−1) is considered to be responsible for the observed slowrate of oxidation.

Published: July 2006

Abstract
Rate constants for reactions with ozone were measured for four kinds of simple ketenes (ketene, methylketene, ethylketene and dimethylketene) in 1 atm of air. The rate constants were obtained as upper limits; &lt;1×10−21, 7×10−19, 1×10−18, and 4×10−17 cm3 molecule−1 s−1, respectively. The mechanism of the reactions was proposed to be similar to that for the liquid-phase reaction.

Authors: Onda Masao , Motoda Takashi , Yamaguchi Ichiro 
Published: July 2006

Abstract
Microwave spectra of 4-chlorophenol were observed in the frequency ranges 8–18 and 26.5–40 GHz. Rotational constants were obtained for the ground vibrational states of three isotopic species, 35ClC6H4OH, 37ClC6H4OH, and 35ClC6H4OD, and for the first excited state of C–Cl out-of-plane bending mode for 35ClC6H4OH. All the b-type Q-branch transition lines of the OH species split into doublets, but those of the OD species do not. The separation of doublets is 158.99±0.16 MHz for the ground state of 35ClC6H4OH. An analysis of the doublets on the basis of the pseudo-symmetric internal rotor model gives the barrier height to the internal rotation of hydroxyl group as V2=13.98±0.37 kJ mol−1 for the 35Cl species. The V2 value obtained is compared with the theoretical V2 value calculated for 4-X-phenols (X=H, F, Cl) by means of ab initio MO with the 4-31G basis set.

Abstract
Benzylviologens with 2,2′- and 3,3′-dimethyl groups embedded in poly (N-vinyl-2-pyrrolidone) matrix indicate reversible photochromisms with absorption maxima at 605 and 775 nm under light, respectively, which are different from those (610, 570 nm) of conventional benzylviologens.
A New Theorem on an Internal Balance in the State Energy
Authors: Isihara Makoto 
Published: July 2006

Abstract
A theorem useful for checking the accuracy of the wave function is presented, which is especially valid and significant for open-shell systems. The theorem connects the kinetic and potential energies of electrons in the up- and down-spin states with one another through an antisymmetric quantity concerned with the spin polarization. Two mutually related derivations of the theorem are shown for the atomic system: One from the hypervirial theorem sets forth the general applicability and the other by the spin-dependent scaling clarifies the variational aspect. The numerical application to restricted and unrestricted analytic self-consistent field wave functions illustrates the sound nature of the theorem. Possibilities of its extension and generalization are touched upon briefly.
Magnetic and Spectral Properties of Dimeric Copper(II) Phenylpropynoate Complexes
Authors: Muto Yoneichiro , Sasaki Ayako , Tokii Tadashi , Nakashima Michio 
Published: July 2006

Abstract
Dimeric copper(II) phenylpropynoate adducts [Cu(Ph–C≡C–COO)2·L]2, where L=benzonitrile, 3,5-dichloropyridine, dimethyl sulfoxide and triphenylphosphine oxide, have been synthesized in order to study the influence of the C≡C group linked to the COO group upon the extent of antiferromagnetic interaction between the two metal ions. Magnetic susceptibility measurements between 80 and 300 K show that the singlet-triplet separation (−2J) ranges from 283 to 318 cm−1. The magnetic behavior of the non-adduct compound Cu(Ph–C≡C–COO)2 is interpreted by taking an inter-dimer interaction into consideration.
Optically Active (2-Aminoethyl)methylphenylarsine and (2-Aminoethyl)butylphenylarsine and Their Palladium(II) and Platinum(II) Complexes
Authors: Shigetomi Yoshiro , Kojima Masaaki , Fujita Junnosuke 
Published: July 2006

Abstract
The chiral bidentate ligands, (2-aminoethyl)methylphenylarsine (mpan) and (2-aminoethyl)butylphenylarsine (bpan) were prepared and resolved by preparing their palladium(II) complexes containing, respectively, (R)-N,N-dimethyl-1-(2-naphthyl)ethylamine and (S)-N,N-dimethyl-α-methylbenzylamine. The optically actaive free arsine ligands can be readily liberated from the palladium(II) complexes, and complexes of the type, [MIIX2L] (MII=Pd, Pt; X=Cl, Br, I; L=R-mpan, S-bpan) were prepared. The absorption and circular dichroism (CD) spectra of these and related complexes were recorded, and the absolute configurations of the arsenic atoms were assigned by comparing the CD spectra with those of analogous phosphine complexes. The optically active arsines in diethyl ether solution racemize by the addition of hydrochloric acid at room temperature, but their palladium(II) complexes in acetonitrile–ethanol solution containing hydrochloric acid are very optically stable and do not racemize by refluxing for a long time.

Published: July 2006

Abstract
A structure analysis of neutron and X-ray diffraction data of liquid methanol was performed by applying a general theoretical procedure for the fluid system composed of molecular clusters. The calculated structure factor curves are found to reproduce the essential features of observed ones. It was concluded that in liquid methanol chain clusters consisting of three or four hydrogen-bonded molecules are dominant on the average.
On the Assignment of Band II in the Electronic Spectrum of [Ni(H2O)6]2+
Authors: Ito Hisao , Sone Kozo 
Published: July 2006

Abstract
[Ni(H2O)6]2+ shows two absorption maxima in the red part of the visible spectrum. The one with the lower frequency has been assigned to the 3A2g→3T1g(F) transition, and the other to the spin-forbidden 3A2g→1Eg transition. A closer comparison with related spectral data, however, makes the reverse assignment more reasonable.

Thermodynamic and Viscometric Studies on the Solution State of Surfynol 465 in Water
Authors: Sato Shizuko , Kishimoto Hiroshi 
Published: July 2006

Abstract
The vapor-pressure depression, surface tension, density and viscosity of the aqueous solution of Surfynol 465, nonionic surfactant, α,α′-[2,4,7,9-tetramethyl-5-decyne-4,7-diyl]bis[ω-hydroxy-poly(oxyethylene)], were measured at various concentrations and 298.15 K, indicating cmc at 11–14×10−3 mol kg−1 and a second cmc at ca. 30×10−3 mol kg−1. From vapor-pressure depression, the association numbers of first and second micelles were approximately estimated at 4 and 13–16, respectively. From the results of density and viscosity measurements, the molar volume and Einstein’s parameter, k, were calculated, respectively. The cohesion between the two hydrophobic chains in monomer was suggested by the analysis of molar volume. It was estimated on the molar volume and k of Surfynol 465 that the hydration of two hydrophilic poly(oxyethylene) chains is significant in monomer as well as micelles, but scarcely changes through micelle formation. The effect of concentration on k was discussed with respect to the shape and interaction of micelles.
Shock-tube Studies of N2O Decomposition and N2O–H2 Reaction
Authors: Hidaka Yoshiaki , Takuma Hirokazu , Suga Masao 
Published: July 2006

Abstract
N2O decomposition and N2O–H2 reaction were studied behind incident and reflected shock waves in the temperature range 1450–2200 K and pressure range 0.6–3.5 atm using both single-pulse and time-resolve techniques. A computer-simulation study was performed to determine the rate-constant expressions of important elementary reactions. Computer calculations showed that the values of the rate constant for N2O+O\xrightarrowk2N2+O2 and N2O+O\xrightarrowk2NO+NO (cited in current papers) are too low. The rate-constant expressions were found to be k2=7.0×1014exp(−28 kcal/RT) cm3mol−1 s−1 and k3=5.6×1014exp (−28 kcal/RT) cm3 mol−1 s−1. The rate constant expression for N2O+H\xrightarrowk2N2+OH, was found to be k4=1.5×1014exp (−15 kcal/RT) cm3 mol−1 s−1.
Assignment of Conjugate Double Bond Systems Produced in Heated PVA Film by Absorption and Excitation Spectra
Authors: Maruyama Kazunori , Akahoshi Hiroshi , Kobayashi Michio , Tanizaki Yoshié 
Published: July 2006

Abstract
Absorption, emission and excitation spectra of heat-treated PVA film have been interpreted as corresponding to mixtures of –(CH=CH)n– and –(CH=CH)n–CO–, which are distinguishable from each other according to whether spectrum is accompanied with fine structures or not. The former shows fine structures and has had n determined to be 2–14 by analysis of peak locations on the basis of linearity for Lewis-Calvin’s plot. For the latter, n has been determined to be 1–7, and Lewis-Calvin’s plot between the wavelength of band maximum and n also shows a good linearity.
Adsorption and Orientation of Isomeric Phthalic Acids on Alumina Surface Observed by Inelastic Electron Tunneling Spectroscopy
Authors: Higo Morihide , Mizutaru Sinichi , Kamata Satuo 
Published: July 2006

Abstract
The vibrational spectra of phthalic, isophthalic and terephthalic acid adsorbed onto the alumina surface have been measured by using inelastic electron tunneling spectroscopy. The tunneling spectra of these acids were obtained by liquid-phase doping with water or various alcohol solutions. The detailed assignments for these spectra are given, together with a comparison of their infrared and Raman spectra. It has been found that both phthalic and isophthalic acid are adsorbed onto the alumina surface mainly as the dicarboxylate ions. However, a comparison between the tunneling spectra of terephthalic and p-acetylbenzoic acid shows that terephthalic acid is adsorbed predominantly as the monocarboxylate ion onto the surface when doped with alcohol solutions. Hydrogen bonding is observed among the adsorbed hydrogen terephthalate ions. These results show a difference in their orientation and different probabilities of chemical interaction between the alumina surface and the carboxyl groups of the adsorbed isomeric phthalic acids.

Authors: Kanda Seiichi , Murray Royce W 
Published: July 2006

Abstract
Electrochemistry of bilayer electrodes has until now been investigated mainly in the dark. For the further development of the photoelectrochemistry of bilayer electrodes and its application to optical-energy storage, a polymer of N-[4-[2-(trimethoxysilyl)ethyl]benzyl]-N′-methyl-4,4′-bipyridinium dibromide (BVSiBr2), a photoredox siloxane polymer, was employed as a photosensitive outer-layer, and bis(2,2′-bipyridine)bis(4-vinylpyridine)ruthenium(II) bis(hexafluorophosphate), [Ru(bpy)2(vpy)2](PF6)2, or tris(4-methyl-4′-viny-2,2′-bipyridine)iron(II) bis(hexafluorophosphate), [Fe(vbpy)3](PF6)2 was electrochemically polymerized as the inner layer on the surface of an SnO2 electrode. Direct and indirect photochemical reductions(trapping) of the outer layer siloxan polymer were attempted in the following ways: 1) the outer-layer, poly(BVSiBr2), was chemically trapped with a methylviologen radical, MV\underset.+, produced photochemically in an illumination cell and transferred to the electrochemical cell, 2) the outer-layer was photochemically trapped by UV irradiation in the presence of photosensitive alcohols (i-PrOH and EtOH) and 3) by photochemical trapping with tris(2,2′-bipyridine)ruthenium and triethanolamine. The 1st and the 2nd methods yielded results expressed by cyclic voltammograms showing an accumulation of poly(BVSi\underset.+), that is, a storage of optical energy in the outer-layer. The result of the 3rd method was negative.

Yields of Solvated Electrons at 30 Picoseconds in Water and Alcohols
Authors: Sumiyoshi Takashi , Tsugaru Kazunori , Yamada Tatsuya , Katayama Meiseki 
Published: July 2006

Abstract
Direct measurements of the yield of hydrated electrons in aqueous solutions and solvated electrons in alcohols were carried out using a stroboscopic picosecond pulse radiolysis system. The yield of solvated electrons was obtained by simultaneous consideration of the pulse shape and radiation doses. The yield at 30 ps after irradiation, G(eaq−)30ps, was determined to be 4.8±0.3 products per 100 eV as compared to the G(eaq−)100ns of 2.7. Experimental values, including the present ones, are higher by 0.3 than the theoretical ones calculated using the spur diffusion model in the time period from 3×10−11 to 10−8 s. Nevertheless, both results show a quite similar time dependence, i.e., fast decay of hydrated electrons in spur reactions. The G-values of solvated electrons at 30 ps were also determined in alcohols. The G-value of solvated electron is 3.4±0.3 in both methanol and ethanol, 2.0±0.3 in 1-propanol and 2.3±0.3 in ethylene glycol.

Published: July 2006

Abstract
The reaction of sodium cyclo-triphosphate(P3m) with l-α- or β-alanine in an aqueous solution was investigated using anion-exchange chromatography, 31P-NMR spectroscopy, chemical analysis for phosphorus and alanine, IR spectroscopy, and thin-layer chromatography(TLC). 1) P3m readily reacted with l-α-alanine at pH 10 and 12 to form two orthophosphate derivatives of α-alanine: N-(1-carboxyethyl)phosphoramidate(P1-(N)ala) and 1,3,2-oxazaphospholidin-2-olate derivative(P1-(N,O)ala) of five-membered ring structure. 2) Only triphosphate derivative, N-(2-carboxyethyl)triphosphoramidate(P3-(N)ala), was obtained in the reaction of P3m and β-alanine. 3) The total yield of P1-(N)ala and P1-(N,O)ala was about 75% when P3m was allowed to react with α-alanine at a molar ratio of 1:3 and pH 12, while the yield of P3-(N)ala was about 80% in the reaction of P3m with β-alanine at a molar ratio of 1:1 and pH 12. 4) Oligopeptides suchs as l-alanylalanine(dimer) and l-alanylalanylalanine(trimer) were formed in the reaction of P3m with α-alanine. 5) Under acidic conditions, P3-(N)ala recyclized to the starting material P3m and β-alanine. 6) The mechanism of the reaction of P3m with α- or β-alanine is discussed.
