Authors: Hong Pangbu , Cho Bo-Re , Yamazaki Hiroshi 
Published: July 2006

Abstract
The reaction of benzene with diphenylacetylene catalyzed by Rh4(CO)12 under carbon monoxide gives triphenylethylene and 2,3-diphenylindenone. The reactions of mono-/di-substituted benzenes with the acetylene also give the corresponding olefins and 2,3-diphenylindenones.
UNUSUAL 1,3-HYDROGEN SHIFT IN THE REACTION OF Na2Fe(CO)4 WITH METHYL E-3-CHLORO-2-BUTENOATE
Authors: Mitsudo Take-aki , Watanabe Hiroyoshi , Watanabe Yoshihisa , Takegami Yoshinobu 
Published: July 2006

Abstract
Methyl E-3-chloro-2-butenoate reacts with Na2Fe(CO)4 in THF at 25°C affording an unexpected [η3-2-(methoxycarbonylmethyl)acryloyl]tricarbonylferrate which has been derived by an unusual 1,3-hydrogen shift. The reaction was rationalized by assuming a (η2-allene)hydridoferrate intermediate.

Authors: Matsubayashi Gen-etsu , Kondo Yasuo , Tanaka Toshio , Nishigaki Satoshi , Nakatsu Kazumi 
Published: July 2006

Abstract
S,S-Dimethylsulfonium 2-picolinylmethylide (PyC(O) \barCH+SMe2, Ydms) reacts with PtCl2(SMe2)2 to give PtCl2Ydms and PtCl(SMe2)(PyC(O)CHCl); the former involves the coordination of both the pyridine nitrogen and ylide carbon atoms, and the latter is a complex with the 2-picolinylchloromethyl ligand which is formed by the fission of the ylide carbon to sulfur bond. An X-ray structure of the latter complex is determined.
SURFACE STATE AND CATALYTIC ACTIVITY OF MoO3/Al2O3 CATALYST IN THE HYDRODESULFURIZATION OF THIOPHENE STUDIED WITH X-RAY PHOTOELECTRON SPECTROSCOPY
Authors: Okamoto Yasuaki , Tomioka Hiroyuki , Imanaka Toshinobu , Teranishi Shiichiro

ASSIGNMENT OF β-PROTON RESONANCES OF l-HISTIDINE BY STEREOSELECTIVE DEUTERIUM SUBSTITUTION
Authors: Kainosho Masatsune , Ajisaka Katsumi , Sawada Seiji , Tanokura Masaru , Miyazawau Tatsuo 
Published: July 2006

Abstract
The 270-MHz 1H NMR spectrum of the mixture of deuterated histidines was compared at pD 8.2 with that of l-histidine. It was seen that the lower-field β-proton resonance disappeared in the deuterated species, in which one of the β-protons was selectively replaced with a deuterium. Accordingly, at this pD, the lower-field β-proton of l-histidine is assingnable to pro-R and the higher-field one to pro-S.

SUBSTITUENT EFFECTS ON 13C CHEMICAL SHIFTS OF KETENIMINES A NEW METHOD FOR DETERMINATION OF σp− CONSTANTS
Authors: Firl Joachim , Schink Karl , Schaschke Horst 
Published: July 2006

Abstract
13C chemical shifts for the benzene ring carbon atoms of a series substituted alkylketene-N-phenylimines 1 – 12 are reported. An excellent linear correlation is found between δci and σp− of the variable substituent χ which allows the determination of new σp− constants. Furthermore, the data suggest that the N-phenyl group rather is conjugated with the C=N-π-bond than with the lone pair.
1,2,3-BENZOTROPOQUINONE
Authors: Kawamata Akira , Kikuchi Emiko , Hirama Masahiro , Fujise Yutaka , Itô Shô 
Published: July 2006

Abstract
The title compound, a benzolog of o-tropoquinone, was synthesized by the DDQ oxidation of the corresponding hydroxytropolone. Effect of benzene annelation on the physical properties (UV, PMR, CMR, electron affinity) of o-tropoquinone was evaluated. The annelation causes more modification to o-tropoquinone than to o-benzoquinone. This may be due to the reduced planarity of 7-membered quinone ring in the title compound. Easy reduction by HCl and facile BF3-induced aromatization to 1,2-dihydroxynaphthalene were observed.

H2–D2 AND 16O2–18O2 EXCHANGE REACTION ON Rh–Sn–γ–Al2O3 AND Ru–Sn–γ-Al2O3 IN RELATION TO THE SIMULTANEOUS REMOVAL OF NO AND CO
Authors: Masai Mitsuo , Murata Keishi , Yabashi Masakazu 
Published: July 2006

Abstract
The activation energy of the exchange reaction increases only slightly in H2–D2 and decreases significantly in 16O2–18O2 by alloying Sn with Rh or Ru on γ-A12O3. Tin promotes the activation of oxygen on Rh– or Ru–γ-Al2O3. The promoting effect of Sn in the removal of NO and CO in the presence of O2 reported before may be due to the activation of oxygen in the reaction.
DISMUTATION OF ALLYL ALCOHOLS TO ALKENES AND α,β-UNSATURATED ALDEHYDES ON THE INTERACTION WITH Ni(cod)2 IN THE PRESENCE OF LIGANDS
Authors: Yamamoto Takakazu , Ishizu Junichi , Yamamoto Akio 
Published: July 2006

Abstract
Allyl alcohols RCH=CHCH2OH (R = H,CH3, C6H5) are converted into corresponding alkenes RCH=CHCH3, α,β-unsaturated aldehydes RCH=CHCHO, and water by the interaction with bis(1,5-cyclooctadiene)nickel Ni(cod)2in the presence of ligands under mild conditions. The formation of the products is explained by assuming oxidative addition of the alcohol to nickel involving O–H or C–OH bond cleavage.
CYCLOADDITION REACTIONS OF 4,6-DIPHENYLTHIENO[3,4-c]-1,2,5-OXADIAZOLE AND -1,2,5-THIADIAZOLE WITH 6,6-DIPHENYLFULVENE AND TROPONE
Authors: Tsuge Otohiko , Takata Toshiaki , Noguchi Michihiko 
Published: July 2006

Abstract
4,6-Diphenylthieno[3,4-c]-1,2,5-oxadiazole (1) reacts as a thiocarbonyl ylide with 6,6-diphenylfulvene to give the exo-[4 + 2] adduct via a stereoselective and regiospecific cycloaddition. The exo-adduct undergoes thermal cleavage of the oxadiazole ring to nitrile and nitrile oxide moieties which can be trapped as 1,3-cycloadducts to the fulvene and dimethyl acetylenedicarboxylate. The reaction of 4,6-diphenylthieno[3,4-c]-1,2,5-thiadiazole (2) with the fulvene affords a mixture of analogous exo- and endo-adducts which are subject to a retro-cycloaddition reaction. On the other hand, 1 reacts with tropone to give the corresponding [4 + 6] adduct which is susceptible to a retro-cycloaddition reaction. However, 2 did not react with tropone.

Authors: Ishikawa Nobuo , Kitazume Tomoya , Nakabayashi Masao 
Published: July 2006

Abstract
Freeze-dried potassium fluoride was found to be much more effective as a hydrogen-bond forming catalytic reagent for alkylation of protic compounds than usual calcine-dried potassium fluoride. Phenol, thiophenol, aniline, and acetylacetone were easily alkylated with methyl or ethyl iodide in the presence of the reagent. Freeze-dried potassium fluoride, however, had no effect for the fluorination of activated chlorine compounds.

Authors: Shinkai Seiji , Hamada Hisatake , Kuroda Hideo , Manabe Osamu 
Published: July 2006

Abstract
3-Hydroxy-N-methylacridinium iodide (Ac+OH) oxidized alcohols with the aid of potassium t-butoxide, whereas N-methylacridinium iodide (Ac+) could not oxidize alcohols under the same reaction conditions. The results indicate that the 3-hydroxyl group is crucial in modifying an N-methylacridinium nucleus as an NAD+ model oxidizing agent.
BIOINORGANIC APPROACH TO THE CYTOCHROME OXIDASE ACTIVE SITE. STRONGLY SPIN-COUPLED COPPER(II)–IRON(III) HETERO-METAL BINUCLEAR COMPLEXES
Authors: Okawa Hisashi , Kanda Wakako , Kida Sigeo 
Published: July 2006

Abstract
Copper(II)–iron(III) binuclear complexes, CuFe(fsaR)Cl·nH2O, with N,N′-bis(3-carboxysalicylidene) alkanediamines (H4fsaR) were prepared and characterized. Cryomagnetic measurements indicated a considerably strong antiferromagnetic spin-exchange interaction operating between the metal ions. The exchange integrals (ca.−50 cm−1) are the largest among the copper(II)–iron(III) complexes so far reported, and hence the complexes mimic the cytochrome oxidase active center.
