Acid Property of Sulfur-Promoted Zirconium Oxide on Silica as Solid Superacid
Authors: Ishida Toshio , Yamaguchi Tsutomu , Tanabe Kozo 
Published: July 2006

Abstract
An SO3-promoted ZrO2/SiO2 was found to be a solid superacid that had the acid strength of higher than H0=−13.16, regardless of the amount of ZrO2 loaded. The sample of 3.5 mmol g−1 of ZrO2 loaded on SiO2, which was the highest amount of loading tested here, showed the highest acid strength of H0≤−14.52. A tetragonal form of ZrO2 was found to grow extensively when the amount of ZrO2 loaded became larger. Thus, it was concluded that the higher acid strength of thus prepared catalyst could be obtained after the crystal growth of supported oxide.

Steric Effects on the Rates of Dissociation of Axially Coordinated Imidazoles in Hindered Low Spin Ferric Porphyrins
Authors: Nakamura Mikio 
Published: July 2006

Abstract
Axially coordinated imidazoles in some low spin ferric complexes derived from meso-tetraphenylporphyrin (TPP) dissociate more rapidly than those derived from meso-tetramesitylporphyrin (TMP). The results have been ascribed to the stability of bis-ligated TMP complex relative to the sterically less hindered TPP analogue.
Distinctive Photochemical Behavior of Rotationally Isomeric 2,5-(trans-4-Octeno)-p-benzoquinones
Authors: Miyake Masaru , Tsuji Takashi , Furusaki Akio , Nishida Shinya 
Published: July 2006

Abstract
Rotational isomers of 2,5-(trans-4-octeno)-p-benzoquinones, (1-A) and (1-B), behave distinctively in the photoreaction. The double bond in the side chain of 1-A cycloadds to the C (2) and C (5) of the quinone moiety, whereas 1-B is reluctant to do so. The results are interpreted in terms of frontier orbital interactions.
