Authors: Watanabe Ken-ichi , Kidokoro Koji 
Published: July 2006

Abstract
Metal chelate catalyzed alcoholysis of pyridinecarbonitriles revealed that the reaction products are alkyl pyridinecarboximidates. The use of copper(II) complexes containing one molecular amine gave good results. The reactivities of alcohols were in the order: methanol&gt; ethanol&gt; butanol&gt; isopropyl alcohol. Cu(II), Ni(II), and Co(II) salts were also effective for the reactions.

A NEW SYNTHETIC PROCEDURE OF N-(2-HYDROXYETHYL)ETHYLENEDIAMINETRIACETATOMANGANESE(III) COMPLEX
Authors: Shirakashi Takashi , Tanaka Nobuyuki 
Published: July 2006

Abstract
When manganese(III) acetate was mixed with Na3hedtra in an acetic anhydride solution, Na[Mn(hedtra)(CH3COO)]·H2O·1/2(CH3CO)2O complex was obtained. This complex was unstable in an aqueous solution, but fairly stable in non-aqueous solvents such as methyl alcohol and dimethyl sulfoxide. This preparative method may be useful to synthesize other manganese(III) complexes.

Authors: Konishi Kazuyori , Onari Yasuo , Goto Shigeki , Takahashi Kensuke 
Published: July 2006

Abstract
The proton magnetic resonance spectra of the title carbanions have been observed in tetrahydrofuran(THF) with lithium as a counter ion. The two methylene protons in these carbanions are nonequivalent at room temperature. This shows that the α-carbon in these carbanions is in a near-sp2 configuration.

Authors: Hisatome Masao , Koshikawa Sakae , Yamakawa Koji 
Published: July 2006

Abstract
Treatment of (1-hydroxy-1-phenylethyl)ferrocene (III) in hexane with O2 in the presence of SiO2 or acidic Al2O3 gave several oxidative dimerization products: butadiene (VIII), 1,4-dihydroxybutane (IX), and tetrahydrofuran derivatives (Xa and b). Production of these compounds suggests formation of an unisolated peroxide (XII) as an intermediate.
UTILIZATION OF THE PROTON SPIN-LATTICE RELAXATION TIMES FOR THE ASSIGNMENT OF METHYL SIGNALS OF SCHIFF BASE CHELATES
Authors: Sakaguchi Ushio , Yoneda Hayami 
Published: July 2006

Abstract
The proton spin-lattice relaxation times have been measured on diamminebis(acetylacetone)ethylenediimino-cobalt(III) ion in D2O using the pulsed Fourier transform method at 100 MHz. The shorter relaxation time of the methyl resonating at lower magnetic field indicates that this methyl signal should be assigned to the methyl groups adjacent to the diimine bridge.

THE ENERGY TRANSFER FOR AN ORIENTED DYE MOLECULES IN STRETCHED POLY(VINYL ALCOHOL) FILMS
Authors: Komiyama Tomoko , Mori Yuji 
Published: July 2006

Abstract
For various stretch ratios, the degrees of polarization(P) of Acridine Orange(AO) cations in stretched poly(vinyl alcohol) (PVA) films has been measured as a function of the concentration of AO cations. The plots of 1/P versus concentration are linear with the slope dependent on the stretching ratio, for concentrations ranging from 4×10−5to 10−4M. This has been interpreted as the results of energy transfer between partially oriented like molecules.

Authors: Iwayanagi Takao , Saito Yasukazu 
Published: July 2006

Abstract

The small magnitude of 1J(Pt–C) in [Pt(C2H4)Cl3]− compared with [Pt(CO)Cl3]− has been interpreted in terms of the s orbital coefficients of Pt and C.

The ligand substitution reaction of Co(II)–PAR complex with EDTA and that of Co(II)–EDTA complex with PAR are inferred.
STEREOCHEMISTRY OF HALOGEN EXCHANGE AND DEHYDROBROMINATION REACTIONS OF 2-BROMOBUTANE OVER COPPER(II) CHLORIDE
Authors: Ishikawa Makoto , Misono Makoto , Yoneda Yukio 
Published: July 2006

Abstract
Inversion of configuration and syn elimination were the favored steric paths, respectively for halogen exchange and for dehydrobromination of 2-bromobutane over CuCl2 at about 100°C. This stereochemistry and slow racemization of 2-bromobutane are in contrast to those observed for 2,3-dibromobutane, and support the idea that the reaction intermediates are sec-butyl cation for 2-bromobutane and a cyclic bromonium ion for 2,3-dibromobutane.

VIBRATIONAL ASSIGNMENTS OF RESONANCE RAMAN LINES OF NI(OCTAETHYLPORPHYRIN) ON THE BASIS OF A NORMAL COORDINATE TREATMENT
Authors: Abe Motoko , Kitagawa Teizo , Kyogoku Yoshimasa 
Published: July 2006

Abstract
Vibrational modes for the resonance Raman lines of Ni(OEP) have been obtained on the basis of a normal coordinate analysis. The Raman line at 1383 cm−1, which corresponds to an oxidation-state marker band of hemoproteins, is mainly due to the breathing mode of the pyrrole rings. The vibrations of the sixteen-membered inner ring contribute to the Raman bands sensitive to the spin-states of the heme iron.

Authors: Kumobayashi Hidenori , Ogura Toshimasa , Akutagawa Susumu , Saito Kaizaburo , Yamaguchi Tsutomu , Tanabe Kozo 
Published: July 2006

Abstract
The metathesis of cyclooctadiene was studied over fourteen kinds of oxides or binary oxides at 40°C in a liquid phase. Only Re2O7–Al2O3 was found to be active. The conversion was 100 % when the concentration of cyclooctadiene was low and the selectivity for the formation of C12, C16, and C20 cyclopolyenes was 64 %. The distribution of C12–C32 cyclopolyenes was entirely different from that in homogeneous catalyst system.
NEW INTERCALATED COMPLEXES OF MPS3 (M=Mg, Zn, Mn) WITH n-ALKYLAMINES
Authors: Yamanaka Shoji , Kobayashi Hidejiro , Tanaka Masami 
Published: July 2006

Abstract
New types of intercalated complexes are synthesized by the reaction of MPS3 layer crystals (M=Mg, Zn, Mn) with n-alkylamines (CnH2n+1NH2, n=1–8). The amines are adsorbed on the interlamellar surfaces of the MPS3 crystals to form two different types of complexes of increased values in basal spacing. The spacing value of the first type of complexes is independent of the number of carbon atoms in alkyl chain of the amines, and the value of the second type of complexes increases with the number of the carbon atoms. The possible arrangements of the amines in the interlayer region are proposed for these types of complexes.

Abstract
The main products of the photochemical reactions of methyl diazoacetate with CBrCl3 and CBr2Cl2 have been unambiguously characterized as CCl3CHBrCO2CH3 and CBrCl2 CHBrCO2CH3, respectively. These results,together with the 1H and 13C CIDNP spectra,support the formation of these products by recombination of radical pairs (Remark: Graphics omitted.) which in turn are formed by preferential attack of carbene :CHCO2CH3 on the bromine atom.

A SHORT FLASH OF MERCURY RESONANCE LINE AT 253.7 NM
Authors: Sato Shin , Okazaki Kiyoshi , Yamabe Masaki , Umemoto Hironobu , Tsunashima Shigeru , Ueno Takumi , Yokoyama Atsushi , Hatano Yoshihiko 
Published: July 2006

Abstract
When helium gas containing mercury vapor was irradiated by the electron pulse from a Febetron 706, an emission of mercury resonance line at 253.7 nm was observed, which consisted of two parts. The lifetime of the first emission agreed with the calculated apparent lifetime of the 6 3P1 state of mercury atoms. The second emission, the peak of which appeared at a few μsec, was completely quenched upon the addition of a small amount of sulfur hexafluoride. The first emission may be due to the direct excitation of mercury atoms by subexcitation electrons produced in helium, while the second emission probably results from the neutralization reaction of mercury ions produced.
