ESR STUDY OF ELECTRONIC EFFECTS AND PREFERRED CONFORMATION OF ALKYL AND SILYL GROUPS ON THE BENZENE CATION RADICAL
Authors: Kira Mitsuo , Nakazawa Hiroko , Sakurai Hideki 
Published: July 2006

Abstract
Cation radicals of several alkyl- and silyl-substituted benzenes in frozen trichlorofluoromethane were investigated by ESR. All the substituents were found to act as an electron donor to the benzene cation, preferring the M–H σ bond eclipsing pπ orbitals. The results may afford a good evidence for the conformational consequences of hyperconjugation.

REGIOSELECTIVE SULFENYLATION OF OXIME DIANIONS. A NOVEL AND USEFUL METHOD FOR THE REGIOSELECTIVE RING CLEAVAGE
Authors: Hiroi Kunio , Otsuka Masahiko , Sato Shuko 
Published: July 2006

Abstract
Treatment of the dianions of cyclic ketoximes with diphenyl disulfide underwent a regioselective sulfenylation at the syn α-carbons. Regioselective alkylation of cyclic ketoxime dianions, followed by sulfenylation with diphenyl disulfide, produced α-alkyl-α′-phenylsulfenyl ketoximes. A Beckmann fragmentation of these sulfenylated ketoximes gave ring cleaved products. This procedure provides a synthetically useful method for the regioselective ring cleavage, remaining valuable functionalities.

BIS(η5-INDENYL)IRON(II)-CATALYZED PHOTOREDUCTION OF METHYLVIOLOGEN
Authors: Akiyama Takeo , Kondo Akira , Omata Makoto , Kajitani Masatsugu , Sugimori Akira 
Published: July 2006

Abstract
Bis(η5-indenyl)iron(II) catalyzes the photoreduction of methylviologen in methanol solutions under irradiation with near ultraviolet light. The quantum yields for the formation of the cation radical of methylviologen (MV\overset+·) with 400–480 nm light are 0.04–0.05. But under light of wavelength shorter than 400 nm bis(η5-indenyl)iron(II) acts as a triplet quencher for the excited methylviologen in the triplet state and lowers the yield of MV\overset+·. A reaction mechanism in which the excited singlet state of bis(η5-indenyl)iron(II) is involved is proposed for the sensitized reduction of methylviologen.

Authors: Hashimoto Kenji , Miura Kouichi , Xu Ji-Jun , Watanabe Akira 
Published: July 2006

The steam gasification rate of the carbon supporting several alkaline metal salts was found to be proportional to the amount of the oxygen measured by the method. Furthermore, the moles of the oxygen trapped by metal on the carbon surface were found to be equal to the moles of metal supported.

SUPPRESSION OF THE CONVERSION OF 3-t-BUTYL-1-METHYL-1-NITROSOTHIOUREA TO 3-t-BUTYL-1-METHYLUREA BY β-CYCLODEXTRIN UNDER ACIDIC CONDITIONS
Authors: Isobe Masayoshi 
Published: July 2006

Abstract
The denitrosation of 3-t-butyl-1-methyl-1-nitrosothiourea(1) was retarded by β-, and γ-cyclodextrins(CDs) at pH 4.70. Decomposition of 1 in the presence of β-CD produced selectively 3-t-butyl-1-methylthiourea(1a), which was remarkably different from the product ratio in the absence of β-CD. These results may be caused by both the protective and the microsolvent effect of β-CD.
