Characteristic Studies on Dealumination of Faujasite-type Zeolite
Authors: Tsutsumi Kazuo , Kajiwara Hisao , Takahashi Hiroshi 
Published: July 2006

Abstract
Aluminium ion was extracted stoichiometrically from the framework of the faujasite-type zeolite by EDTA treatment. Dealuminated zeolites with various silica/alumina ratios (from 4.80 to 10.29) were obtained. A dealuminated zeolite does not necessarily show the molecular-sieve-type adsorption isotherm of nitrogen. The lattice constant of zeolite decreases with the silica/alumina ratio. The zeolite with an increased silica/alumina ratio has a higher catalytic activity for a cumene-cracking reaction than the parent H-Y4.80 zeolite. It is suggested, on the basis of infrared spectroscopic and calorimetric measurements, that the total number of acid sites decreases with dealumination, while the number of strong acid sites increases. These strong aicd sites seem to contribute to the catalytic activity of dealuminated zeolite.
The Crystal Structure of 2,4,6-Triphenylpyrylium-1,1,3,3-tetracyanopropenide, [(C23H17O)+·(C7HN4)−]
Authors: Tamamura Toshiaki , Yamane Takashi , Yasuoka Noritake , Kasai Nobutami 
Published: July 2006

Abstract
The crystal structure of an organic charge transfer salt 2,4,6-triphenylpyrylium-1,1,3,3-tetracyanopropenide has been determined by means of X-ray diffraction. The crystals are monoclinic in the space group P21/a. The unit cell dimensions are: a=13.024, b=21.357, c=8.324Å, β=94.56°. The cation and the anion are nearly planar and form an “ion-pair.” The crystal is built up from infinite columns stacked by these ion-pairs along the c axis. Between two adjacent anions in the neighboring columns, a weak hydrogen bond (C–H···N 3.265 (5), H···N 2.185(4) Å) is present. The charge transfer interaction between the anion and the cation seems to have less influence on the crystal structure than the electrostatic force or the hydrogen bonding.
The Synthesis and Spectroscopic Study of Some Bis(tertiaryphosphine)bis(N,N-dialkylselenocarbamate) Complexes of Palladium(II) and Platinum(II)
Authors: Tanaka Koji , Tanaka Toshio 
Published: July 2006

Abstract
Ten N,N-dialkylselenocarbamate complexes of palladium(II) and platinum(II), [(C6H5)3P]2Pd[SeC(O)NR2]2(1), [(C6H5)3P]2Pt[SeC(O)NR2]2 (2) (R=CH3, C2H5, n-C3H7, and n-C4H9), [CH3(C6H5)2P]2Pd[SeC(O)N-(CH3)2]2 (3), and [CH3(C6H5)2P]2Pt[SeC(O)N(CH3)2]2 (4), have been prepared. The infrared spectra and molecular-weight determinations indicate that the selenocarbamate ligand is bonded to the palladium(II) or platinum(II) through the selenium atom, with a free carbonyl group in the solid state, while in 1 and 2 two and one triphenylphosphine dissociate in a dilute solution to exist as compounds with bidentate selenocarbamate, Pd[SeC(O)NR2]2 and [(C6H5)3P]Pt[SeC(O)NR2]2, respectively. The 1H- and 31P-NMR spectra of 3 and 4 reveal that they have a trans-configuration. The same configuration is suggested for the N,N-dibutyl derivative of 2 on the basis of the spin-spin coupling constant between the 31P and 195Pt nuclei.
Bromine Addition Reaction to Olefins with Magnesium Bromide and Aroyl Peroxides
Authors: Okubo Masao , Kusakabe Hisahiro , Hiwatashi Tsunenori , Kishida Kazuo 
Published: July 2006

Abstract
When MgBr2 prepared in anhydrous tetrahydrofuran was added to a mixture of olefin and benzoyl peroxide, the peroxide decomposed at a moderate rate at room temperature. Olefin dibromide and magnesium benzoate were obtained in nearly quantitative yields. The effects of p- and m-substituents of peroxide and of the structure of olefin were studied. A complex consisting of MgBr2 and peroxide was formed. Abstraction of brominium cation from the complex by the olefinic double bond was proposed.
Products Obtained by the Reaction of Trichlorotrimethylbenzenes with Fuming Nitric Acid. Side-chain Nitrooxylation versus Oxidation to Unsaturated Cyclic Ketones
Authors: Suzuki Hitomi , Maruyama Shigeru , Hanafusa Terukiyo 
Published: July 2006

Abstract
The reaction of trichlorotrimethylbenzenes with fuming nitric acid has been investigated. Trichloropseudocumene underwent both side-chain nitrooxylation and nuclear oxidation to give 2,5,6-trichloro-3,4-dimethylbenzyl nitrate, 3,5,6-trichloro-2,4-dimethylbenzyl nitrate, and 3,6-dichloro-4-nitro-2,4,5-trimethylcyclohexa-2,5-dienone. Trichloromesitylene yielded a mixture of several carbonyl compounds, from which 3,5-dichloro-4-hydroxy-2,4,6-trimethylcyclohexa-2,5-dienone and two nitro-ketones, tentatively formulated as 2,4,6-trichloro-5-hydroxy-6-nitro-2,3,5-trimethylcyclohex-3-enone and 3,5-dichloro-2-hydroxy-6,6-dinitro-2,4,5-trimethylcyclohex-3-enone, were obtained as crystalline products by chromatography and fractional extraction. Trichlorohemimellitene behaved similarly towards the nitrating agent to give 2,6-dichloro-4-hydroxy-3,4,5-trimethylcyclohexa-2,5-dienone as the major product. The competitive modes of side-chain nitrooxylation and formation of cyclic ketones have been described.

Also, the oscillator strength for the π,π* transition was obtained in terms of the dipole length and the dipole velocity.
The Phenanthrene/Anthracene–Picric Acid System
Authors: Koizumi Shigeo , Matsunaga Yoshio 
Published: July 2006

Abstract
The phase relations in the phenanthrene/anthracene–picric acid system have been determined by calorimetry and X-ray diffraction. Four series of solid solutions occur in this system: the terminal solid solutions P and A, which are based on the parent picrate lattices, and the I and II solutions, which are based on the incongruentlymelting ternary compounds. A eutectic is observed at about 47 mol% anthracene and at 124 °C. Enantiotropic transitions appear at about 76, 103, and 120 °C in the I solid solution and at about 80, 103, and 120 °C in the II solid solution. The Gibbs energy of formation from the solid component compounds has been estimated as −2.04, −1.67, −1.21, and −0.68 kcal/mol for the stable forms at the room temperature of the phenanthrene picrate, the I solid solution (at 34.58 mol% anthracene), the II solid solution (at 58.96 mol%), and the anthracene picrate respectively. The two transitions in the phenanthrene picrate have been shown to be easily detectable by recording the electrical resistivity as a function of the temperature.

Authors: Hagio Katsuaki , Yoneda Naoto , Takei Hisashi 
Published: July 2006

Abstract
The cyclic sulfonium ylides, 4-dimethylsulfuranylidene-2,3-dioxotetrahydrofuran derivatives (8), were synthesized in good yields by reactions of methyl and ethyl dimethylsulfuranylidenepyruvates (3 and 4) with carbonyl compounds. The reactions of 8 with p-toluenesulfonyl chloride and benzoyl chloride gave 4-methylthio-3-(p-toluenesulfonyloxy)- and 4-methylthio-3-benzoyloxy-2-oxo-2,5-dihydrofuran derivatives respectively in high yields. The ylides (8) reacted with mercaptans to afford 4-substituted products (14–16), whereas, on the reactions with thiourea, the demethylation of the dimethylsulfonium group proceeded exclusively.

Abstract

Interaction between Carbon Dioxide and the Zinc Oxide Surface
Authors: Morimoto Tetsuo , Morishige Kunimitsu 
Published: July 2006

Abstract
The adsorption of carbon dioxide has been measured at 25°C on zinc oxide surfaces with different amounts of preadsorbed carbon dioxide. As a result, it has been found that carbon dioxide molecules are chemisorbed more weakly to zinc oxide surfaces than water; the desorbability of carbon dioxide is almost complete upon evacuation at temperatures higher than 300 °C, whereas upon evacuation at 25°C 80% of the carbon dioxide remains on the surface. Also, the adsorption isotherms of carbon dioxide have been obtained at 25°C on differentlyhydroxylated surfaces of zinc oxide. On such surfaces, the adsorption amount of carbon dioxide decreases linearly with an increase in the amount of surface hydroxyl groups. This suggests that most of the carbon dioxide is adsorbed strongly on the vacant sites formed by dehydroxylation, and not on the surface hydroxyl groups.
Preparation of Stable 2,3-Dihydroindolizines by the Reactions of Pyridinium Methylides with Various Acrylates
Authors: Kakehi Akikazu , Ito Suketaka 
Published: July 2006

Abstract
Pyridinium methoxycarbonylmethylides(5–8), readily obtainable from their corresponding salts(1–4), reacted with various acrylates to afford dimethyl 2,3-trans-dihydroindolizine-1,3-dicarboxylate derivatives(9–20) in moderate yields. These dihydroindolizines were very stable and were not aromatized by heating. However, treatment with lead tetraacetate gave the corresponding indolizine derivatives(21–32) in good yields. The configuration at C-2 and C-3 positions in these dihydroindolizines was assigned to trans from their NMR and by comparison with an authentic specimen(12).
The Effects of the Composition of Raw Cadmium Sulfide on the Characteristics of Cadmium Pigments
Authors: Tsunashima Makoto , Takahashi Hiroshi 
Published: July 2006

Abstract
The effects of the S/Cd mol ratios of cadmium sulfide precipitates on the particle size, the hexagonality, and the brightness of cadmium pigments were studied. The precipitates were prepared by mixing an aqueous solution of cadmium nitrate with either sodium sulfide or hydrogen sulfide. Then, cadmium pigments were made of these precipitates by heat-treatment under an atmosphere of oxygen or nitrogen. The characteristics of the pigments were affected by the following three factors; particle size, hexagonality, and brightness. These factors were closely related to the S/Cd mol ratio of the precipitates of the cadmium pigments. We found the minimum points on the curves of the particle size, the hexagonality, and the brightness in relation to the S/Cd mol ratio. From these results, it was concluded that the optimum range of the S/Cd mol ratios of the precipitates for the characteristics of the cadmium pigments was 0.98±0.01.
Photocyclization of [2.2]Metacyclophane at 2537 Å
Authors: Sorimachi Kenji , Morita Toshifumi , Shizuka Haruo 
Published: July 2006

Abstract
The photochemical reaction of [2.2]metacyclophane at 2537 Å has been studied spectrophotometrically. Photocyclization took place to give 4,5,9,10-tetrahydropyrene not only in aerated but also in degassed solutions. The quantum yields for the reaction were independent of the irradiation time, concentration of starting material, light intensity, and addition of piperylene. However, the reaction quantum yields increased with temperature rise. The quantum yields in the aerated system were somewhat larger than those in the degassed system. Radiationless deactivation in S1(ππ*) was very efficient, whose quantum yield was assumed to be ∼0.99, judging from the small reaction quantum yield (less than 0.01) and the lack of fluorescence and phosphorescence. It is proposed that the photocyclization of the molecule originates from S1(ππ*) to give intermediate M which is subsequently convreted into the product or the starting material. Activation energies in these processes were estimated.
Photochemistry of the Electron Donor-Acceptor System. I. Exciplex Fluorescence and the Fluorescence of the Charge-Transfer Complex in the Aromatic Hydrocarbon–Fumaronitrile System
Authors: Shirota Yasuhiko , Tsushi Isamu , Mikawa Hiroshi 
Published: July 2006

Abstract
The fluorescence of a series of aromatic hydrocarbons was quenched by the addition of fumaronitrile, which is consistent with the charge-transfer or electron-transfer mechanism. The fluorescence quenching was accompanied by the appearance of a new, broad structureless emission band attributed to the fluorescence from the exciplex in non-polar or slightly polar solvents. In highly polar solvents only quenching of the fluorescence occurred. The energies of the band maxima of the exciplex fluorescences and the magnitude of the ionization potentials of a series of fluorescers showed a good correlation with each other. Solvent and temperature dependence of the exciplex fluorescence was examined and discussed. The present aromatic hydrocarbon-fumaronitrile system also formed a charge-transfer complex in their ground states at relatively high concentrations of each component. The selective excitation of the ground state charge-transfer complex gave rise to the fluorescence emission in a fluid solution at room temperature at the same wavelength region as observed for the exciplex fluorescence. It was susgested that the electronic structure of the fluorescent state of the exciplex and the excited charge-transfer complex is the same.
An MO Study on the Hydrogen Bond System of H2O–HF
Authors: Yamabe Shinichi , Kato Shigeki , Fujimoto Hiroshi , Fukui Kenichi 
Published: July 2006

Abstract
An LCAO MO SCF calculation has been carried out on H2O–HF system with a minimal STO-3G basis set, with respect to three assumed models, i.e. SIGMA, PI, and BIFURCATED models. A configuration analysis of the wave function has shown that charge-transferred electron configurations weakly mix into the original electron configuration in the SIGMA and PI models, while the contribution of charge-transferred configurations is negligibly small in the BIFURCATED model. The SIGMA model has been found to be most stable mainly due to the Coulombic attraction energy between the two species. The intermolecular electron density between the two interacting systems has been investigated by means of a concept of orbital interaction, leading to a conclusion that the mixing-in of the occupied MO’s of H2O with the unoccupied MO’s of HF contributes slightly to the hydrogen bond in the SIGMA and PI models.
Properties of Protective Films Formed on an Iron Surface by Dialkyl Phosphate as a Corrosion Inhibitor
Authors: Nakagawa Satoru , Hashizume Genzo 
Published: July 2006

Abstract
The properties of films formed on an iron surface by di-n-dodecyl phosphate were studied. The inhibition effects for iron specimens treated with dodecyl phosphate were estimated from the losses in weight of iron specimens in 5% NaCl aqueous solutions. The Fe Lα, Lβ X-ray emission spectra of the iron surface were obtained by electron microprobe X-ray analysis. The value of the intensity ratio, Fe Lβ/Lα, of the untreated iron specimen was 0.17, while that of the treated iron specimen was 0.28. The infrared spectrum of the treated iron surface was similar to that of tribasic orthophosphate. The content of Fe in the film formed on the iron surface by di-n-dodecyl phosphate was from 4.3% to 6.98%. From these results, it was inferred that di-n-dodecyl phosphate reacted with iron atoms at the iron surface in a cyclohexane solution and that the main component of the film formed on the iron surface was [(RO)2POO]2Fe or [(RO)2POO]3Fe.

Abstract
The complexes of rhodium (III), iridium(III), palladium(II) and platinum(II) with piperidine-, piperazine-, N-methylpiperazine-, morpholine- and thiomorpholine-dithiocarbamate have been prepared and characterized by spectroscopic methods. From the electronic absorption spectra the values of the ligand field parameters were determined. The nephelauxetic parameters are indicative of a strong covalency in the metal-ligand bond. A monomeric structure for the complexes is suggested. All the new compounds here reported are diamagnetic.

The Transisopropylation of Naphthalene
Authors: Shimada Keizo , Nagahama Shizuo 
Published: July 2006

Abstract
The transisopropylation of naphthalene with p-cymene and isopropylxylenes in the presence of aluminum chloride–nitromethane complex as a catalyst was studied. It was observed that the α-isomer initially formed was isomerized to the β-isomer in the reaction with isopropyl-p-xylene. However, when p-cymene or isopropyl-o-xylene was used, the isomer distribution was almost constant from the beginning to the end of the reaction. This was attributed to the fact that the hydride abstraction mechanism plays a role in the latter case.
