Rhodium Catalyzed Anti-Markovnikov Addition of Triphenylphosphine to 1,3-Dienes A Novel Method to Separate Pure (Z)-1,3-Alkadienes from Isomeric Mixtures
Authors: Arisawa Mieko , Momozuka Ryohei , Yamaguchi Masahiko 
Published: September 2002

Abstract
Rhodium-catalyzed addition of triphenylphosphine and trifluoromethanesulfonic acid to (E)-1,3-dienes gives (E)-3-alkenylphosphonium salts in the anti-Markovnikov mode. The addition reactions to (E)-1,3-dienes proceed more rapidly than those to (Z)-1,3-dienes, which can be utilized to separate pure (Z)-1,3-dienes from isomeric mixtures.

Authors: Watanabe Yutaka , Munetsugu Hirofumi , Hayashi Minoru 
Published: September 2002

Abstract
To compare the synthetic utility of cyclic xylylene N,N-diethylphosphoramidite and its acyclic analog, dibenzyl ester, both phosphites derived from them with dipalmitoylglycerol were subjected to the selective phosphorylation at the OH-3 position in 1,2:4,5-di-O-cyclohexylidene-myo-inositol in the presence of pyridinium tribromide, and the cyclic version showed to be much superior to the acyclic. The 3-O-phosphorylated product was conveniently converted into phosphatidylinositol 4-phosphate.

Abstract
The reaction of ΔL-[Co(L-Hcys-N,S)(en)2](ClO4)2 with NaOH and AgClO4 in a 2:2:1 ratio in water gave a 2:1 (Co:Ag) adduct, (ΔL)2-[Ag{Co(L-cys-N,S)(en)2}2]3+ ((ΔL)2-[1]3+), while the corresponding reaction with AgNO3 led to the isolation of a 3:1 adduct, (ΔL)3-[AgNa{Co(L-cys-N,S)(en)2}3]5+ ((ΔL)3-[2]5+). The discrete trinuclear structure in (ΔL)2-[1]3+ and the 2D polymeric structure in (ΔL)3-[2]5+ were determined by X-ray crystallography.

Three thiirene 1-oxides 1, which possess bulky alkyl substituents at the 2- and 3-positions, afforded α-iminothio-ketones in 59–69% yields on successive treatment with trifluoroacetic anhydride and p-toluenesulfonamide, whereas 1 furnished oxazoles in 65–89% yields on the same treatment with trifluoroacetic anhydride and p-toluamide. A mechanism involving ring-expansion of the initial intermediates, sulfilimines, is proposed for these reactions.

Authors: Sasaki Takeo , Shimada Teruyuki , Tachibana Koji 
Published: September 2002

Abstract
The photorefractive properties of side-chain liquid crystalline polymers possessing cyanobiphenyl chromophores were investigated.

Published: September 2002

Abstract
Solid-state CD of bovine serum albumin in dry thin films exhibited different spectra depending on the sample preparation method and the rotation positioning of a film. It was revealed that this is due to the macroscopic anisotropies of the samples and not due to the protein conformation transition during the film formation, as suggested in literature.

Excited State Structure of N-(4-cyanophenyl)carbazole by Time-Resolved Infrared Absorption Spectroscopy
Authors: Samanta Anunay , Saha Satyen , Ishikawa Hironori , Hamaguchi Hiro-o 
Published: September 2002

Abstract
Nanosecond time-resolved infrared absorption spectroscopy has been used to study the charge transfer characteristics of the title compound in electronically excited states. The transient infrared bands observed at 2090 cm-1 and 2060 cm-1 have been attributed to the CN stretch modes in the first excited singlet and triplet states of the molecule. These frequencies are in conformity with enhanced charge separation in the excited states. Comparison of the present result with the existing data for 4-(N,N-dimethylamino) benzonitrile has indicated that the CN stretch frequency is not a direct measure of the polarity of the excited states of these molecules.

Abstract
Oxygen permeation property of A-site partially substituted barium cobaltites, A′xBa1-xCo0.7Fe0.3O3-δ (A′=Ba, Pr, Gd, Dy, Y and Yb), were examined. Substitution of Ba by Dy, Y or Yb was found to stabilize cubic perovskite structure even when x remained as small as 0.05. As a result, oxygen permeation through the disks made of these oxides appeared at temperature lower than 500 °C, and reached fairly high levels at elevated temperature.
