Freezing Bond Rotation by a Pin in Cyclopentadienyl(cyclobutadiene)cobalt(I) Complexes. A New Type of Atropisomerism
Authors: Uno Mitsunari , Shirai Kazuhiko , Ando Katsuhiro , Komatsuzaki Nobuko , Tanaka Takanori , Sawada Masami , Takahashi Shigetoshi 
Published: March 2006

Abstract
The X-ray crystallographic and CD spectral analyses of Cp1Co(C4Ar4), 1 and 2, reveal that the (−)-menthyl group on a C5 ring restricts the free rotation of single bonds between C4 ring and phenyl groups even in solution and induces a helical chirality on the C4Ar4 moiety; complexes 1∼4 provide the new type of atropisomerism originating from freezing bond rotation by a pin stuck from the C5 ring into a four-blade windmill on the C4 ring.
Sodium Ion Sensing by Cellulose Triacetate Plasticizer Membrane Containing Dibenzo-16-crown-5 Chromoionophore
Authors: Hayashita Takashi , Kumazawa Mitsuaki , Lee Jong Chan , Bartsch Richard A 
Published: March 2006

Abstract
We have designed new optical membrane sensor which is composed of cellulose triacetate polymer as a membrane support, o-nitrophenyloctyl ether as a membrane plasticizer and sym-(decyl)(2-hydroxy-5-nitrobenzyloxy)dibenzo-16-crown-5 (1) as a Na+ ion selective chromoionophore. This type of membrane was found to selectively respond to Na+ in the detection limit of 10−5 M (1 M = 1 mol dm−3) with no significant interference from Li+ and K+ ions.

Authors: Kusama Hiroyuki , Uchiyama Katsuya , Yamashita Yuko , Narasaka Koichi 
Published: March 2006

Abstract
Intramolecular cyclization reaction on the nitrogen atom of oximes of p-hydroxybenzylacetone derivatives proceeds by the treatment with tetrabutylammonium perrhenate and trifluoromethanesulfonic acid in refluxing 1,2-dichloroethane to afford azaspirodienones in good yield. The azaspirodienones are transformed into quinolines via dienone-phenol rearrangement.

Authors: Matsubara Hirokazu , Takada Makoto , Koyama Shinichi , Hashimoto Kazuhito , Fujishima Akira 
Published: March 2006

Abstract
TiO2-containing papers with highly photocatalytic activity have been prepared. Their photocatalytic activity was investigated by measuring the decomposition of gaseous acetaldehyde under illumination from a weak UV light source such as a conventional white fluorescent light bulb. It was found that the photocatalytic efficiency of the TiO2-containing papers was higher than that of Degussa P-25, one of the most efficient commercial TiO2 powders, indicating that paper pulp serves as a good matrix for highly efficient TiO2 photocatalysts.

Published: March 2006

Abstract
Tosyl group of 3,4-disubstituted 2-tosylpyrroles easily rearranged from 2- to 5-position by treatment with TFA. The ratio of the regioisomers at equilibrium was definitely influenced by the bulkiness of the substituent at 3-position of the starting 2-tosylpyrroles.
Improvement of Photocatalytic Activity and Product Selectivity by Cadmium Metal Deposited in situ on Suspended Cadmium(II) Sulfide Particles
Authors: Ohtani Bunsho , Kusakabe Satoshi , Nishimoto Sei-ichi , Matsumura Michio , Nakato Yoshihiro 
Published: March 2006

Abstract
Effect of annealing of commercial crystalline CdS powders on their photocatalytic activity and product selectivity was investigated for stereoselective diamino-N-cyclization of 2,6-diaminopimelic acid operated in a deaerated aqueous solution. Surface analyses revealed the formation of sulfur vacancy, which promotes the photoinduced cadmium metal (Cd0) deposition. The Cd0, detected by reduction of methylviologen, may act as a reduction site for photoexcited electrons.

Authors: Kyushin Soichiro , Sakurai Haruaki , Yamaguchi Hiroyuki , Goto Midori , Matsumoto Hideyuki 
Published: March 2006

Abstract
Decaisopropyl-7-oxabicyclo[2.2.1]heptasilane was synthesized by oxidation of decaisopropylbicyclo[2.2.0]hexasilane with m-chloroperbenzoic acid, and its structure was determined by X-ray crystallography. The compound shows unusual properties in the UV spectrum due to the interaction of the n orbital of the oxygen atom and the Si-Si σ bonds. The compound also shows far stronger fluorescence than the bicyclic ladder polysilane.

New Chiral Diphosphines, 2,3-Bis(siloxy)-1,4-bis(diphenylphosphino)butanes, and Their Cationic Rh(I) Complexes: Synthesis and Structures
Authors: Tamao Kohei , Nakamura Kazunori , Yamaguchi Shigehiro , Shiro Motoo , Saito Seiki 
Published: March 2006

Abstract
A series of 2,3-bis(siloxy)-1,4-bis(diphenylphosphino)butanes SILOPs, possessing various siloxy groups, and their Rh(I) complexes have been prepared. The X-ray structure of a SILOP shows a staggered conformation with two siloxy groups in the anti positions. The X-ray crystal structure of a cationic Rh(I)-SILOP complex, however, shows an anti arrangement of not the two siloxy groups but the two silyl groups with respect to the O–O axis, which reinforces the C2-symmetrical environment around the metal center.

The Effects of High Magnetic Field on the Deposition of Silver
Authors: Katsuki Akio , Watanabe Shin-ichi , Tokunaga Ryoko , Tanimoto Yoshifumi 
Published: March 2006

Abstract
Deposition of silver was observed under a high gradient magnetic field. When a copper wire was placed on a piece of filter paper which was wet with silver nitrate aqueous solution (0.5 mol dm−3), the deposition of silver grew uniformly around the wire at zero field. In the presence of the magnetic field (Bmax = 8 T), the area of the deposition at the center of the magnetic field decreased. Diffusion of ions generated in the reaction seems to be affected by the high gradient field.

Authors: Fujitsuka Mamoru , Sato Tadatake , Watanabe Akira , Ito Osamu , Shimidzu Takeo 
Published: March 2006

Abstract
Photochemical polymerizations of dithienothiophenes were investigated. Photo-irradiation to the solution containing dithienothiophene and appropriate electron acceptor gave poly-dithienothiophene having ca. 104 (vs. PSt.) of molecular weight. The cation radical of the monomer was efficiently generated through photoinduced electron transfer from the excited state of the monomer to the electron acceptor. Then the successive coupling reaction resulted in a formation of the polymers.
