Authors: Okano Tamon , Kiji Jitsuo , Toyooka Yoshiharu 
Published: September 2003

Abstract
The cyanation of aryl iodides with NaCN under heptane-water two-phase conditions is efficiently catalyzed by PdCl2{PPh2(m-C6H4SO3Na)}2 in the presence of zinc chloride and NaBH4, and gave the corresponding aryl nitriles in high yields. The biphasic cyanation had an advantage in that the aryl nitriles are easily separated from the mixtures of catalyst and reagents.

Published: September 2003

Abstract
The surrounding fields around cobalt ions in the pore-free inorganic-organic hybrid materials were controlled through coordination bonds by various functional groups directly bonded to the silica framework.

The pore volume of the hybrid materials was changed against the methyltrimethoxysilane to total silane ratio.

While most of the addition took place to the β-face of the carbonyl, the senecioate-derived enolate surprisingly preferred α-face attack in ether solvent in contrast to β-face attack in THF.
Radiolysis of CFC-113 Adsorbed on a Molecular Sieve
Authors: Yamamoto Yukio , Tagawa Seiichi 
Published: September 2003

Abstract
Molecular sieve 13X adsorbing CFC-113 was irradiated with γ-rays and then was soaked in water. The concentrations of Cl− and F− of the supernatant solutions increased with irradiation time, indicating that both defluorination and dechlorination of CFC-113 occur. The dechlorination proceeds by a chain reaction when 2-propanol is adsorbed on the molecular sieve together with CFC-113. It is suggested that the dehalogenation of CFC-113 is promoted by the molecular sieve.

Catalytic Combustion of Methane over Pd Supported on Metal Oxides
Authors: Widjaja Hardiyanto , Sekizawa Koshi , Eguchi Koichi 
Published: September 2003

Abstract
A Pd/SnO2 catalyst demonstrated excellent activity for low temperature catalytic combustion of methane inspite of its low surface area. Palladium clusters were observed as an intimately contacted layer on fine SnO2 particles. Temperature programmed desorption of oxygen revealed that methane combustion was found to be dependent on the adsorption state of oxygen on palladium. It is considered that catalytic activity is strongly influenced by the existence of interaction between palladium and tin oxide.
