Published: May 2003

Abstract
A stable, crystalline carbenium iodide, which possesses a thiocarbonyl group at the β-position, shows ambident reactivities, thereby reacting with a hard nucleophile OH− at the carbenium carbon atom and with a soft nucleophile RLi at the thiocarbonyl sulfur atom. Thermal dissociation of the MeLi adduct to a carbene and a ketene dithioacetal is also presented.
Isolation of Bright Blue Fluorescent Substances from Sonochemical Hydroxylation of Methyl p-Cyanobenzoate
Authors: Yamada Sachiko , Hokari Hajime , Akasaka Shinji , Iwamura Michiko 
Published: May 2003

Abstract
Sonochemical hydroxylation of methyl p-cyanobenzoate (1a) in water gave a bright blue fluorescence, which are mainly ascribed to three new fluorescent compounds, 3-hydroxy, 2,3-and 2,5-dihydroxy derivatives of 1a. Other benzenes substituted with electron-withdrawing groups also gave similar fluorescence from their hydroxylated derivatives. Among the fluorescence substances, methyl 2,5-dihydroxybenzoate was supposed to be applicable for a fluorescent chemosensor.
Synthesis, Characterization and Structure of Mu-7, a New Layered Aluminophosphate with a 4 × 8 Network
Authors: Vidal Loïc , Gramlich Völker , Patarin Joël , Gabelica Zelimir 
Published: May 2003

Abstract
A new layered aluminophosphate (Mu-7) was prepared in a quasi non aqueous system, using methylformamide (MF) as solvent in addition to restricted amounts of water. MF is decomposed during the synthesis and the resulting methylamine is found occluded in the interlayer spacing of this new material. Mu-7 is built from zigzag ladder chains leading to layers containing only 4- and 8-membered rings. It is the first layered aluminophosphate having a 4 × 8 network.
Asymmetric Distribution of Artificial Boundary Lipid as Analysed by NMR Deconvolution
Authors: Ueda Takehiko , Zhou Zhe , Sunamoto Junzo 
Published: May 2003

Abstract
Asymmetric distribution of an artificial boundary lipid between the outer and inner leaflets of multilamellar vesicles (MLVs) was determined by the modified 1H-NMR peak deconvolution technique. The asymmetry was affected by the vesicle preparation method, suggesting that a relatively high energy state of lipid bilayer is required for the boundary lipid to promote its specific function.
DNA-Controlled Photoisomerization of Bis(2-(1-methyl-pyridinium-4-yl)vinyl)benzene
Authors: Juskowiak Bernard , Takenaka Shigeori , Takagi Makoto 
Published: May 2003

Abstract
The photoisomerization study of bis(2-(1-methylpyridinium-4-yl)vinyl)benzene dye in the absence and the presence of DNA revealed that the DNA affects photoisomerization quantum yields of the ligand. The DNA-promoted formation of an E,E isomer was accounted for the contribution of two factors: (i) the binding differentiation between structurally. dissimilar isomers and (ii) the quenching of ligand fluorescence by the DNA.

Authors: Ishida Akihiko , Kaneko Emiko , Yotsuyanagi Takao 
Published: May 2003

Abstract
By constructing a self-ordered nearly perfect ring system, a new type of visual test method has been developed. Poly(vinyl alcohol) forms a sharp ring–like solid phase (10.6 mm diameter) when a 100-μl drop of its aqueous solution was evaporated on a poly(vinyl chloride) plate. Aluminium ion of 1 – 30 ppb has been determined visually as a fluorescent 1:1 chelate of 2,2′-dihydroxyazobenzene concentrated into the ring.

Authors: Hirotsu Masakazu , Kojima Masaaki , Mori Wasuke , Yoshikawa Yuzo 
Published: May 2003

Abstract
The reaction of a tripodal tetradentate ligand (H2L = N,N-bis(2-hydroxybenzyl)-N′,N′-dimethylethylenediamine) with Fe(ClO4)2·6H2O and a carboxylic acid in basic methanol generates an iron(III) species under aerobic conditions. Further addition of an Mn2+ cation gave a heterotrinuclear complex, [{FeIII(L)(carboxylato)(OCH3)}2MnII]. On the other hand, an additional Fe2+ cation gave a μ3-oxo homotrinuclear complex, [{FeIII(L)(carboxylato)}2OFeIII(OCH3)]. Drastic changes in the structure were induced by the addition of metal ions.

Perfect Control of Diastereomeric Complexation of C2-Symetric Chiral 1,1′-Bis(oxazolinyl)ferrocene Ligands
Authors: Imai Yoshitane , Zhang Wanbin , Kida Toshiyuki , Nakatsuji Yohji , Ikeda Isao 
Published: May 2003

Abstract
Upon complexation with Pd(II), both chiral 1,1′-bis(oxazolinyl)ferrocene ligand 1 and its planar chiral derivative 2 afforded the corresponding 1:2 ligand-Pd(II) complex. On the other hand, upon complexation with copper(I) chloride, both 1 and 2 afforded only one of the two possible diastereomeric 1:1 ligand-Cu(I) complexes. The twists of the two Cp rings of the copper(I) complexes of 1 and 2 are opposite to each other, which is ascribed to the effect of the planar chirality in 2.
2-(2-Pyridyl)ethylsilyl Group as a New Class of Electroauxiliary. Fine Tuning of the Electron Transfer Driven Reactions by the Dynamic Coordination to Silicon
Authors: Yoshida Jun-ichi , Suga Seiji , Fuke Ken-ichi , Watanabe Mitsuru 
Published: May 2003

Abstract
The introduction of 2-(2-pyridyl)ethyl group on silicon decreases the oxidation potentials of silyl-substituted heteroatom compounds. The molecular orbital calculations indicate that this effect is attributed to the dynamic coordination of the pyridyl group to silicon in the cation radical intermediate. Such coordination also facilitates the selective C-Si bond cleavage.

This network affords channeling cavities with dimension of about 2 × 4 Å along the c-axis.
Palladium Catalyzed Coupling Reaction of Acylchromate Complexes and Allylic Bromides
Authors: Sakurai Hidehiro , Tanabe Katsuhiko , Narasaka Koichi 
Published: May 2003

Abstract
A cross-coupling reaction between acylchromate complexes and allylic bromides takes place under CO atmosphere in the presence of a catalytic amount of Pd(PPh3)4 to afford the corresponding allylic ketones in good yield. The same reaction also proceeds by adding RNC under argon atmosphere in place of CO atmosphere. Thus, the acylchromate complex works as a good acyl donor for Pd catalyzed acylation reaction.

Development of Catalyst-Membrane System for Oxidative Coupling of Methane by Water
Authors: Terai Takami , Li Xiaohong , Tomishige Keiichi , Fujimoto Kaoru 
Published: May 2003

Abstract
It has been reported that SrTi0.4Mg0.6O3−δ catalyst showed good performance for the oxidative coupling of methane by using water as an oxidant (2CH4 + *H2O → C2H6 + *H2 + H2O). But the yield of C2 hydrocarbons in this reaction was almost constant at W/F=5-20 gh/mol. SrCe0.95Yb0.05O3−α tube-type membrane was utilized to remove H2 selectively in coupling of methane to C2 hydrocarbons from CH4 and water. When SrTi0.4Mg0.6O3−δ catalyst was used in this catalyst-membrane system, the yield of C2 hydrocarbons was drastically promoted.

Authors: Komatsuzaki Nobuko , Himeda Yuichiro , Goto Midori , Kasuga Kazuyuki , Sugihara Hideki , Arakawa Hironori 
Published: May 2003

Abstract
Novel Ru-Ni and Ru-Cu dinuclear complexes, in which Ru(bpy)22+ (bpy=2,2′-bipyridine) and Ni- or Cu-Schiff base unit fused together, were synthesized. The molecular structure of Ru-Ni dinuclear complex was determined by an X-ray crystal structure analysis. Photochemical studies on these complexes showed that the excited state of the Ru(bpy)22+ moiety in the dinuclear complexes was quenched by intramolecularly attached metal-Schiff base unit.
Photoinduced Intramolecular Proton Transfer and Intermolecular Hydrogen-Atom Abstraction of 1-Piperidinoantraquinone (PAQ)
Authors: Nakayama Toshihiro , Nagai Nobuaki , Torii Yukiyoshi , Hamanoue Kumao 
Published: May 2003

Abstract
The lowest excited singlet and triplet states of PAQ give rise to formation of the N-ylide compound at 77 K and the reduced compound at room temperature, respectively. In the latter case, however, indirect population of the lowest excited triplet state from a higher excited singlet state (through a higher excited triplet state) is very important.
Synthesis and Gas Occlusion of New Micropore Substance Rhodium(II) Carboxylates Bridged by Pyrazine
Authors: Mori Wasuke , Hoshino Hiroyuki , Nishimoto Yuko , Takamizawa Satoshi 
Published: May 2003

Abstract
Rhodium(II) carboxylates bridged by pyrazine occlude a large amount of N2 gas, reversibly. The maximum amounts of the occluded N2 gas were 1.8, 1.1, 0.8, 0.6, 0.2, 0.2, 0.5, and 0.6 mol per one mole of rhodium(II) salt with benzoate, o-hydroxybenzoate, m-hydroxybenzoate, p-hydroxybenzoate, o-toluate, m-toluate and p-toluate, respectively, indicating the presence of a large number of micropores in these rhodium(II) carboxylates.
The porous structure which is formed by self-assembly of linear rhodium(II) carboxylates–pyrazine was deduced from the magnetic susceptibilities and by analogy to the structure of copper(II) dicarboxylates which show similar gas-occlusion behavior.
