HOMOLOGATION OF METHANOL CATALYZED BY MIXED TRANSITION METAL CLUSTERS CONTAINING COBALT
Authors: Hidai Masanobu , Orisaku Masami , Ue Makoto , Uchida Yasuzo , Yasufuku Katsutoshi , Yamazaki Hiroshi 
Published: July 2006

Abstract
Syntheses of mixed transition metal clusters containing cobalt and their catalytic activities for homologation of methanol were investigated. The reaction of RuCl3 with Na[Co(CO)4] gave a reddish brown complex Na [RuCo3(CO)12]. The cluster easily underwent a cation exchange to give the Cs+ and [Et4N]+ salts. These clusters showed a remarkable catalytic activity for homologation of methanol. The selectivity of ethanol was increased up to 51% in ca. 40% conversion in case of [Et4N]+ salt. Catalytic activities of some other mixed metal clusters were also examined.

LIPOSOME FUSION AS MONITORED BY A FLUORESCENCE QUENCHING TECHNIQUE
Authors: Sunamoto Junzo , Iwamoto Kiyoshi , Iwamoto Hidetoshi , Kondo Hiroki , Kano Koji , Ogawa Teiichiro 
Published: July 2006

Abstract
The fluorescence emission from ethyl ω-(1-pyrenyl)decanoate (EP) is quenched by 4-dodecyl-N,N-dimethylaniline (DDA) in liposomal bilayers according to the collisional quenching mechanism without heteroexcimer formation. This phenomenon was utilized to monitor liposome fusion between two small and single-walled vesicles. When a set of two liposomes, F-liposome containing the fluorophore EP and Q-liposome containing the quencher DDA, was incubated and passively sensitized by Ca(II) ion or a lipophilic agent (solanesol) , significant quenching of EP fluorescence was observed. This was ascribed to the encounter of the fluorophore and quencher in the bilayers upon liposome fusion.

Thermolyses of dimethylsulfonium 1-(2,6-diphenyl and 2,3,5,6-tetraphenyl-4H-pyran-4-yl )-2-oxo-2-phenylethylides (1 and 3) caused a novel [1,3] ylide rearrangement to give dimethylsulfonium 1-benzoyl-6-oxo-2,6-diphenyl and 2,3,5,6-tetraphenyl-2,4-hexadienylides (6 and 7), respectively. The formations of oxy-thio-acetal derivatives (11 and 12) of 4-pyranylidene from 3 and its methylphenylsulfonium analogue (4) by base treatment are also reported.
PHOTOLYSIS OF CHLOROBENZENE. PHENYLATION OF CHLOROBENZENE WITH ANOMALOUS ORIENTATION
Authors: Kojima Masanobu , Sakuragi Hirochika , Tokumaru Katsumi 
Published: July 2006

Abstract
Photolysis of chlorobenzene as neat and in concentrated solutions gives a mixture of o-, m-, and p-chlorobiphenyls in an anomalous ratio, with the highest ratio of the p-isomer. However, on dilution with solvent, the isomer ratio tends to approach the normal ratio as obtained from the usual phenylation of chlorobenzene with the highest ratio of the o-isomer. A mechanism is proposed in which a triplet excimer of chlorobenzene arising in concentrated solutions favours the production of the p-isomer.

Authors: Tsuge Otohiko , Oe Koji , Kawaguchi Noriyuki 
Published: July 2006

Abstract
Irradiation of 4,5-cis-2,3,4,5-tetraaryloxazolidines and 3-aryl-3a,9b-dihydroacenaphth[1 ,2-d]oxazolidines generates the corresponding aziridine intermediates with elimination of aldehyde formed by fissions of the C2–O and C4–C5 bonds in the former and the C2–O and C2–N bonds in the latter, respectively. The intervention of aziridine intermediates was proved by photo-cycloadditions.

Authors: Nakamura Teiji , Misono Makoto , Yoneda Yukio 
Published: July 2006

Abstract
The reducibility of La1-xSrxCoO3 (a perovskite-type mixed oxide) remarkably increased with the Sr2+ content, x, but the rate of re-oxidation of the reduced catalysts decreased with x. These trends well explain the catalytic activity for oxidation on the basis of redox mechanism.

SPECTROSCOPIC STUDIES ON THE AGGREGATION OF CHLOROPHYLL a IN THE PRESENCE OF WATER-SOLUBLE MACROMOLECULES
Authors: Uehara Kaku , Nakajima Yasuhiro , Yonezawa Masahiro , Tanaka Makoto 
Published: July 2006

Abstract
The characteristic aggregation of chlorophyll a (chl a) was induced when a small amount of acetone solution of chl a was added to a diluted aqueous solution of a macromolecule such as poly(vinyl alcohol)(PVA), poly(vinyl pyrolidone)(PVP), or bovine serum albumin(BSA). The rate and state of aggregation were remarkably affected by the kind of polymer used. PVA fairly rapidly induced the aggregation to form aggregates having absorption maxima at 730 nm. On the other hand, BSA showed a tendency to conserve a typical 672 nm colloidal form.

Authors: Tanaka Koji , Miyake Shin-ichi , Tanaka Toshio

Kinetic studies indicate that the reaction proceeds via a mono-capped trigonal prismatic intermediate which is formed by the coordination of DMAC to molybdenum from the bottom of the square pyramid of 1, affording the final product by the intramolecular rearrangement.

Authors: Koden Mitsuhiro , Yagyu Tadao , Takenaka Shunsuke , Terauchi Hikaru , Kusabayashi Shigekazu 
Published: July 2006

Abstract
A homologous series of cholesteryl 4-(4′-n-CnH2n+1-benzoyl)benzoates (n=0–15) was prepared. Whereas these molecules have a large bent shape around the carbonyl group, all homologues show a cholesteric phase. In addition, the homologues with n=7–15 show two kinds of smectic phases. The effect on these mesophases of increasing the alkyl chain length is quite striking. Cholesteryl and benzophenone portions are indispensable for the mesomorphism.

Abstract
The two-step open cycle, the reduction of In2O3 by carbon and its reoxidation by water, was applied to produce hydrogen from water. Various carbons could be used as the reductants. Of these, chars from biomass are highly effective to the reduction of In2O3, and consequently to the production of hydrogen. K2CO3 is also a good catalyst to the two-step hydrogen production.
