A CONVENIENT METHOD FOR THE HYDROLYSIS OF VINYL CHLORIDES TO KETONES
Authors: Mukaiyama Teruaki , Imamoto Tsuneo , Kobayashi Susumu 
Published: July 2006

Abstract
A new and useful method for the hydrolysis of vinyl chlorides was investigated by the combined use of TiCl4, methanol and water. Various vinyl chlorides, such as α-chlorostilbene, 1-phenyl-1-chloro-1-propene and 2,6-dimethyl-4-chloro-3-heptene, were hydrolyzed to corresponding ketones in high yields at room temperature. Steroid I was smoothly converted to testosterone propionate II in 96% yield by this method.
THE CRYSTAL STRUCTURE OF CATENA-μ-ETHYLENEDIAMINECADMIUM(II) TETRACYANOCADMATE(II) DIBENZENE CLATHRATE: Cd(en)Cd(CN)4·2C6H6
Authors: Iwamoto Toschitake 
Published: July 2006

Abstract
The crystals of Cd(en)Cd(CN)4·2C6H6 belong to the tetragonal space group P42/mmc with the dimensions a = 8.262(6) and c = 15.495(2) A (Z = 2). The three-dimensional host lattice is built of the network of Cd-CN-Cd and Cd-en-Cd linkages to form two kinds of cavities for the guest benzene molecules. The host en and the guest C6H6 molecules are so flexible and dynamic that precise atomic positions can hardly be determined.

Authors: Yamamoto Masahide , Ohoka Masataka , Kitagawa Kuniharu , Nishimoto Sei-ichi , Nishijima Yasunori 
Published: July 2006

Abstract
Photochemical formation of VCZ cation radical and electron acceptor anion radical has been demonstrated by means of flash spectroscopy for the VCZ-electron acceptor systems where exciplex emission can be observed. The ion radicals are produced by one photonic process and they decay by bimolecular recombination.

Authors: Muto Masayuki 
Published: July 2006

Abstract
New synthetic methods of bis(ethylenediamine)- and tetraammine-chromium(III) complexes using the matrix method in the liquid state are described. The starting materials are [Cr en3](C1O4)3 and [Cr(NH3)6](C1O4)3. Dimethylsulfoxide and dimethylformamide are used as solvents. The anions (X or L; see text) to be coordinated are added in the form of NH4X and H2L (or HL).
INFRARED REFLECTANCE SPECTRA OF CHEMISORBED FORMATES ON EVAPORATED COPPER AND ALUMINUM SURFACES
Authors: Ito Masatoki , Suëtaka Wataru 
Published: July 2006

Abstract
Infrared spectra of HCOO− and DCOO− chemisorbed on evaporated copper and aluminum surfaces have been observed by high sensitivity reflection techniques. The absence of the antisymmetric OCO stretching band for species on the copper film suggests that the chemisorbed formate molecules are orientated almost vertically on smooth surfaces.

REACTIONS OF COPPER-CARBENOIDS WITH SULFOXIDES
Authors: Takebayaski Matsuji , Kashiwada Toshinobu , Hamaguchi Masashi , Ibata Toshikazu 
Published: July 2006

Abstract
The copper chelate-catalyzed reaction of α-diazoacetophenones with substituted diphenyl sulfoxides gave two types of products, diaryl sulfides (V) and oxosulfonium ylides (VI), of which ratios depended on the substituents of α-diazoacetophenones and of diaryl sulfoxides. The oxosulfonium ylides exhibit a novel reaction with phenylglyoxal affording oxosulfonium glyoxalylphenacylides (VII) in the presence of copper acetylacetonate. When copper-phthalocyanine was employed as a catalyst, the reaction gave a lactone (X) besides (V).

Authors: Ohno Shin-ichi 
Published: July 2006

Abstract
An ab initio calculation of the primary radiolysis yields was examined. The method is based on the classical theory developed by Thomas in 1927 for the collision between two free moving electrons. The results of applying it to the irradiation of He with 100 keV-electrons are: Gion = 2.42, Gex(n 1p) = 0.91, and Gex(n 3S, n 3P) = 0.13.

Authors: Tadokoro Shin-ichi , Fujiwara Shizuo , Ichihara Yoshihiro 
Published: July 2006

Abstract

The α- and carbonyl carbons showed upfield displacements of 2.3 and 3.4 ppm, respectively, due to the helix-coil transition of the compound. The clearly split peaks assigned to each side-chain carbon of PLM in the α -helix and the random-coil form were observed in the range of the helix-coil transition.

Authors: Mori Yoshihiro , Ooyasu Tetsuo , Matsuda Hiroyuki 
Published: July 2006

Abstract
The translation of Na+ with an eluent on strong electrolyte cation exchanger column is larger than that of K+, but with electromigration smaller than that of K+. An effective separation of Na+ and K+ may be expected with a simultaneous use of ion-exchange and electromigration. When an electric field[150 v(between electrodes), 3.3 mA] was applied on a strong electrolyte cation exchanger(Diaion PK-228) column(height; 10 cm, diameter; 1 cm) with parallel but reverse direction to the eluent(0.1 N NH4Cl) flow, Na and K(each 0.5 meq) have been separated perfectly by the elution.

Authors: Oki Michinori , Sugawara Tadashi , Iwamura Hiizu 
Published: July 2006

Abstract
Strong anomeric effect is observed in 1,3,5-trithiane derivatives. Phenylthio-axial conformation is found to be more stable than the equatorial in 2-phenylthio-1,3,5-trithiane in contrast to the fact that the anomeric effect is very small in 2-alkylthiothiane. 2-Benzoyloxy-1,3,5-trithane exists solely as the benzoyloxy-axial conformer.

THE RADICAL ANION OF SODIUM 9,10-ANTHRAQUINONE-2-SULFONATE STABILIZED BY BINDING WITH MICELLES
Authors: Kano Koji , Matsuo Taku 
Published: July 2006

Abstract
The radical anion of sodium 9,10-anthraquinone-2-sulfonate, which was produced by the photolysis of the quinone in aerobic aqueous solution (pH 8.0) containing appropriate amounts of anionic and/or non-ionic surfactants, was detected by means of ESR and UV spectroscopy. The formation of the radical anion was observed above pH 6.8. Relationship between the concentration of surfactant and that of the radical anion gave a profile which showed the typical micellar effects. It is suggested that the micelles protect the radical anion from quenchers, such as oxygen, water, and other reagents, because the radical anion is incorporated into the micellar interior.

METHYLSULFONIUM SALTS OF 1,3,5-TRITHIANE
Authors: Iwamura Hiizu , Fukunaga Michio 
Published: July 2006

Abstract
Mono-S-methylation of 1,3,5-trithiane (1) is effected smoothly by heating 1 in dimethyl sulfate or in methyl p-toluenesulfonate. A mixture of cis- and trans-1,3-dimethylbissulfonium salts of 1 is obtained by methylation with the Meerwein or Borch reagents. With all attempts no trimethylation of 1 is successful. Nucleophilicity of the last sulfur atom is suppressed to a considerable extent by the two sulfur atoms already methylated.

Published: July 2006

Abstract
A marked concentration dependence was observed for the circular dichroism of poly-γ-(1-naphthylmethyl)-l-glutamate in ethylene chlorohydrin. This fact was explained in terms of the formation of the β-structure in the solution at high concentrations of the polyglutamate and the subsequent restriction of the side chain orientation relative to the dissymmetric field in the solution.

Authors: Nishida Shinya , Imai Toshiro , Tsuji Takashi 
Published: July 2006

Abstract
p-Tolyl and phenyl trideuterioacetates were thermolyzed in a vacuum. H1 -nmr of the produced p-cresol showed no deuterium incorporation at its ortho position, which disfavoured the 6-membered cyclic mechanism. Pressure-independence of the yield of phenol made the radical chain mechanism unlikely, too. A possible mechanism is proposed.
