THE EFFECT OF SOLVENT ON THERMAL CRACKING OF BIBENZYL AS A COAL MODEL
Authors: Chiba Koji , Tagaya Hideyuki , Yamauchi Taku , Thukahara Yoshitaro 
Published: July 2006

Abstract
The effect of solvent on bibenzyl conversion depends on the nature of solvent. Triphenylmethane, diphenylmethane, and diphenylamine are poor hydrogen donor solvents. But, when these compounds were used as solvent, bibenzyl conversion was markedly enhanced, and toluene, stilbene and adducts were formed. Moreover, when a proper amount of tetralin was mixed with the above solvent, toluene was solely obtained in reasonable yield.

Authors: Kosugi Masanori , Sumiya Takashi , Ohhashi Kenji , Sano Hiroshi , Migita Toshihiko 
Published: July 2006

Abstract
Direct transformation of aryl bromides to benzylic alcohols by means of hydroxymethyltributyltin in the presence of palladium complex was attained in moderate yields, although the catalytic efficiencies were rather low, and the reaction could not be applied to aryl bromides having strong electron-withdrawing group. These problems were solved by using the trimethylsilyl-protected tin compound.

Authors: Yoneyama Hiroshi , Hirai Takayuki , Kuwabata Susumu , Ikeda Osamu 
Published: July 2006

Abstract
Anodic polymerization of pyrrole at Nafion-coated ITO or Au electrodes gives a polypyrrole-Nafion co-polymer film at the Nafion/electrode substrate interface. Sulfonate groups of Nafion and not the electrolyte anions are involved in the polymerization process. The redox reaction of the resulting polymer film occurs more easily than that of polypyrrole films prepared on the naked electrode substrate.

Authors: Dao Lê H , Perrier Gérard 
Published: July 2006

Abstract
Sublimed films of α-form hydroxyaluminum phthalocyanine (α-PcAlOH) can be transformed into a novel polymorph by a treatment with aqueous acid solutions. The spectroscopic characterization of the new polymorph, showing its particular visible and IR spectra and X-ray diffraction pattern was achieved by comparing with other polymorphs. The dimorphic transformation of PcAlOH is also associated with a dramatic enhancement in photoactivity as shown in the performance of a photoelectrochemical cell based upon a PcAlOH/redox junction.
Stable Configuration of Ester-Stabilized Azomethine Ylides. Stabilization of anti-Form by 1,5-Dipolar Interaction and of syn-Form by Hydrogen Bonding
Authors: Tsuge Otohiko , Kanemasa Shuji , Ohe Masayuki , Yorozu Kiyotaka , Takenaka Shigeori , Ueno Kazunori 
Published: July 2006

Abstract
Stable configuration of ester-stabilized azomethine ylides is found to depend upon the substituent on the ylide nitrogen. Thus, N-substituted azomethine ylides derived from N-substituted 2-aminoacetates and carbonyl compounds undergo cycloaddition with olefinic dipolarophiles predominantly in anti forms, while N-protonated (or N-unsubstituted) azomethine ylides generated from 2-iminoacetates exclusively in syn forms.

High-pressure Cycloaddition Reaction of Tropone with Furans
Authors: Sugiyama Shigeru , Tsuda Tohru , Mori Akira , Takeshita Hitoshi , Kodama Mitsuaki 
Published: July 2006

Abstract
Thermal reactions of tropone with furan and 2-methoxyfuran gave mainly the endo-[4+2] cycloadducts at 3000 bar. In the latter case, the products further reacted with tropone to yield 2:1-adducts. The NMR spectral data defined their stereochemistry; predominant formation of endo-adduct is rare in the Diels–Alder reaction of furans. This must be due to the conditions employed, under which the cycloreversion is prevented.

Authors: Machida Masato , Eguchi Koichi , Arai Hiromichi 
Published: July 2006

Abstract
Effect of additives on the surface area of oxide supports was investigated to use them for combustion catalysts above 1000 °C.
