LASER FOURIER IMAGING OF CHEMICAL REACTION. OBSERVATION OF THE DIFFUSION PROCESS OF HEAT EMITTED FROM DYE MOLECULES BY STRIPED LASER EXCITATION
Authors: Ishizaka Shozo , Urano Toshiyuki , Tokumaru Katsumi 
Published: July 2006

Abstract
Excitation of Eosin Y in ethanol solution with irradiated stripes of chopped argon ion laser beam gives thermal fringes which diffract helium-neon laser beam; the resulting diffraction fringes correspond to the Fourier transformation of the thermal fringes. By following the growth and decay of the transient diffraction signals the diffusivity of heat evolved by the photoexcitation in the solution was determined.

Authors: Endo Tadashi , Takei Hiromichi , Guro Kazuo , Yamashita Minoru , Yonenaga Shu , Ito Masato M , Matsushita Kazuhiro 
Published: July 2006

Abstract
Environment dependence of the selectivity in oxidation of a pair of associating thiols was examined in binary solvent mixtures of an alcohol or acetonitrile with water and an organic cosolvent. The discrimination between the two nonpolar groups (n- and i-C5H11 groups, phenyl and p-tolyl groups, or n- and i-C4H9 groups) of one of the thiols was found to occur more specifically in aqueous media than in the corresponding nonaqueous media.

Authors: Takizawa Akira , Sato Morimasa , Kinoshita Takatoshi , Tsujita Yoshiharu 
Published: July 2006

Abstract
Photo-induced membrane potential changes were observed for solid membrane of poly(l-glutamic acid)(PGA) with azobenzene groups in the polymer side chains (azo-modified PGA) . The increase in membrane potential indicates an increase in negative fixed charge concentration of the membrane, i.e., an increase in the degree of dissociation of the l-glutamic acid CO2H side chains in the membrane via the trans to cis isomerization of the azo groups on UV irradiation.

SELECTIVE FORMOSE REACTION INITIATED BY PHOTO- AND γ-IRRADIATION
Authors: Irie Setsuko 
Published: July 2006

Abstract
A selective formose synthesis was achieved by photo- and γ-irradiation of formaldehyde in the presence of base. Photoirradiation of aqueous formaldehyde solution gave pentaerythritol as a single product, while γ-irradiation resulted in the formation of glycolaldehyde as the main product. These results suggest that the formose reaction under photo- and γ-irradiation is considerably different from the thermal formose reaction.

NEW C–C BOND FORMATION WITH PYRIDINIUM METHYLIDE: HYDROMETHYLENATION OF OLEFIN
Authors: Tsuge Otohiko , Kanemasa Shuji , Kuraoka Satoru , Takenaka Shigeori 
Published: July 2006

Abstract
New C–C bond formation with pyridinium methylide is presented: Pyridinium methylide reacts with electron-deficient olefins providing the next higher homologs of olefins, in which the double bond of starting olefin is saturated and, instead, a C=C double bond is newly formed. This reaction mode has been never reported before in the study of nitrogen ylide and is to be referred to as hydromethylenation of olefin. In the presence of base, 1,2-double bond migration occurs leading to the methylated derivatives of starting olefins.
