MxOy/SO42−/Dealuminated Zeolite β (M=Ti, Fe) as Novel Catalysts for Alkylation of Isobutane with 1-Butene
Authors: Sun Mingxing , Sun Jianwei , Li Quanzhi 
Published: September 2003

Abstract
A new kind of MxOy/SO42−/H-form dealuminated β (DHβ) catalysts prepared here were applied to alkylation of isobutane with 1-butene. The group of MxOy/SO42−/DHβ (M=Ti, Fe) catalysts has a lower rate of deactivation and higher selectivity of this alkylation than other group of Hβ and DHβ. It is proposed that the strong acid sites corresponding to the active sites for this alkylation can be formed by the interaction among DHβ, MxOy, and SO42−.

Authors: Nakanishi Waro , Hayashi Satoko 
Published: September 2003

Abstract
The magnetic shielding tensor was calculated with the GIAO theory for some selenium compounds of versatile structures. The calculated chemical shifts of the selenium nucleus (δc(Se)) correlated well with the observed ones (δo(Se)), showing the reliability of the method. The δc(Se) values for p-substituted benzeneselenols also explained the δo(Se) values of aryl selenides of various structures around the Se-C bonds.

The CH=C-N,N21′,N22′-linked bis (porphyrin) consisting of an N-(vinyl)octaethylporphyrin moiety and a monoprotonated N21,N22-vinylidene-bridged meso-tetraphenylporphyrin moiety was rearranged to the CH=C-N,N21′,N22′-linked bis(porphyrin) consisting of an N-(vinyl)-meso-tetraphenylporphyrin moiety and a monoprotonated N21,N22-vinylidene-bridged octaethylporphyrin moiety.

Abstract
(2-Hydroxyethyl)trimethylammonium silicate and titanium bis(triethanolaminate) were allowed for a reaction in methanol.The reaction proceeded without breakdown of the Si8O208− structure of the silicate to give SiO2-TiO2 gels. Heat-treatment of the gels at 650-1000 °C in air for 1 h yielded SiO2-TiO2 powders with high surface areas (496-127 m2 g−1, respectively), whose TiO2 component is dominantly present as anatase.

Authors: Ohno Keiichi , Matsuura Hiroatsu , Iwaki Toru , Suda Taiichiro 
Published: September 2003

Abstract
Remarkable changes in the (N)CH3 stretching wavenumbers have been observed for amines on protonation. These C–H stretching wavenumbers are related linearly to the corresponding C–H bond lengths calculated by the ab initio method. The (N)CH3 stretching bands are useful for distinguishing between free and protonated amines.

Authors: Shibata Ikuya , Fukuoka Shoji , Baba Akio 
Published: September 2003

Abstract
Allyl epoxides were prepared by the chemoseletive allylation at the carbonyl groups of α-bromo ketones with allylic tin, where PbI2-HMPA effected as a chemoselective catalyst. Moreover, vinyl epoxides were obtained in one pot procedure by the PbI2-HMPA catalyzed reaction of γ-chloroallyltri-n-butyltin with aldehydes. Because of the mildness of the catalyst, the formed epoxide functionalities were not decomposed.

Authors: Okeya Seichi , Hashimoto Masato , Matsuo Takahito , Yamanaka Kimiko , Sumino Tetsuya , Hashimoto Hiroshi , Kanehisa Nobuko , Kai Yasushi 
Published: September 2003

Abstract
Five-coordinate anionic complexes, [Pt(hfac)2X]− (X = Cl, Br, I), were prepared by reaction of [Pt(hfac)2] and [PPh4]X in CH2Cl2. A distorted square pyramidal structure was revealed by the X-ray analysis. The variable-temperature 1H and 19F NMR spectra of these complexes were explained by two independent dynamic motions in solution, which were considered good models for the ligand exchange and cis-trans isomerization reactions.
Synthesis and Electrochemical Properties of LiNiO2 Prepared via an Aqueous Solution Technique
Authors: Garcia B , Pereira-Ramos J P , Caurant D , Baffier N 
Published: September 2003

Abstract
LiNiO2 cathode materials have been prepared using a soft chemistry route. Precipitation of hydroxide is followed by drying and heating in the temperature range 650-900 °C under oxygen flow and leads to shorter preparation time than with powders mixing methods usually used. The sample LiNiO2 obtained at 700 °C shows the best electrochemical behaviour. This has been attributed to a low lithium deficiency.

Authors: Murata Shigeru , Tsubone Yasuhiro , Tomioka Hideo 
Published: September 2003

Abstract
The deuterium isotope effect for the intramolecular CH insertion reaction of the nitrene photolytically generated from 2-(2-phenylethyl)phenyl azide in cyclohexane is obtained as 14.7 ± 0.3 at 20 °C, which supports the hydrogen abstraction-recombination mechanism involving the triplet state nitrene. The temperature dependence of the isotope effect suggests the operation of the tunneling of the hydrogen atom in this process.

The stereochemistry of the transformation was determined and the plausible mechanistic pathway is proposed.

Authors: Kajiyama Tisato , Oishi Yushi , Suehiro Kazuaki , Hayashi Yukinori , Kuriyama Keisuke , Kuri Taishi 
Published: September 2003

Abstract
Moiré patterns of bilayered fatty acid monolayers prepared by the Langmuir-Blodgett method were successfully observed on the basis of dark field imaging by using transmission electron microscope for the first time. The moiré lines of the bilayered fatty acid monolayers prepared by the continuous compression method were warped and discontinuous, whereas that prepared by the multi-step creep method were straight and continuous. These differences apparently reflect their crystallographical regularities.

Abstract
Nonbridged zirconocene dichlorides, (1,2-Me2-4-RC5H2)2ZrCl2(R = Me(3), Ph(4), p-FC6H4(5), 2-furyl(6), 2-thienyl(7), and Fc(8)), and meso- and rac-(1-Me-3-PhC5H3)2ZrCl2(9 and 10), in the presence of MAO show a high catalytic activity (8.1∼17.4 × 106 gPP/molZr·h) in the polymerization of propylene and produce almost an atactic elastomeric polymer of high molecular weight (Mw = 10.5∼23.2 × 104). In contrast, rac-(1-Me-3-t-BuC5H3)2ZrCl2(12) shows very low activity and produces a rather high isotactic polymer of low molecular weight.

Authors: Ohtani Bunsho , Bowman Robert M , Colombo D Philip , Kominami Hiroshi , Noguchi Hidenori , Uosaki Kohei 
Published: September 2003

Abstract
Pump-probe diffuse reflectance measurements were carried out on particulate titanium(IV) oxide photocatalysts in the form of aqueous suspension and dry powder. A linear relation between second-order rate constants of electron-hole recombination for the suspension and powder systems was seen by analyses of decay profile of charge carriers. Presence of air gave negligible effect on the recombination kinetics, but loading of platinum (Pt) significantly reduced the rate constant.
Origin of Deactivation of Chlorobenzene in Aromatic Electrophilic Substitution
Authors: Tomoda Shuji , Takamatsu Kuniyuki , Iwaoka Michio 
Published: September 2003

Abstract
Deactivation of chlorobenzene in aromatic electrophilic substitution may arise from the unique energy level of chlorine lone pair orbital which is higher than the subjacent π-molecular orbital of benzene (π1), in sharp contrast to the widely accepted concept that inductive electron-withdrawing property (−I effect) of chlorine should be responsible for ring deactivation. The role of π1 in protonation at C-4 is found to be as important as the frontier orbital (π2).
A New Active Catalyst for Single Step Synthesis of Methyl Isobutyl Ketone from Acetone
Authors: Coh Byoung-Youl , Hur Jin Mok , Lee Ho-In 
Published: September 2003

Abstract
2wt% Ni-CaO catalyst prepared by sol-gel process showed 70-80% acetone conversion and 60% MIBK selectivity at 200 °C of reaction temperature. The incorporated Ni influenced CaCO3, catalyst intermediate, to readily decompose into CaO, active basic component, and CO2 at even 500 °C. Meanwhile, Co or Pd did not influence CaCO3 decomposition at the same temperature of 500 °C and showed no catalytic activity. That is, Ni played a role as promoter for catalyst activation as well as active site of hydrogenation.
External Magnetic Field Effect on the Photoinduced Magnetization in a Cobalt Iron Cyanide
Authors: Einaga Yasuaki , Ohkoshi Shin-ichi , Sato Osamu , Fujishima Akira , Hashimoto Kazuhito 
Published: September 2003

Abstract
We studied the external magnetic field effects on the photoinduced magnetization of a cobalt iron cyanide, K0.4Co1.3[Fe(CN)6]·5H2O. Photoinduced magnetization value was increased ca. 20 % at maximum under the magnetic field of 50000 G at 5 K. In addition, in the ferrimagnetic region (T &lt; Tc = 26 K), the external magnetic field accelerated the rate of photoinduced spin generation. Those data suggest that external magnetic field increases magnetic interaction between the excited state and spin clusters.
