Authors: Hayashi Nobuyoshi , Sugawara Tohru 
Published: July 2006

Abstract
Kinetic equations for controlling the consecutive reactions in the reduction of a Schiff base, formed by the equilibrium reaction of an amino acid with a 2-keto acid, have been developed and applied to a computer-assisted automatic synthesis of substituted N-(carboxyalkyl)amino acids. The equations were especially useful for the prediction of optimum reaction conditions and on-line reaction control.

Temperature Dependence of the Mixed-Valence States in 1′,1'″-Bis(o-methylbenzyl)biferrocenium+ TCNE−
Authors: Nakashima Satoru , Masuda Yuichi , Sano Hirotoshi 
Published: July 2006

Abstract
1′, 1'″-Bis(o-methylbenzyl)biferrocenium+ TCNE− was synthesized and its mixed-valence state was studied by means of ESR and Mössbauer spectroscopy. It was found from Mössbauer spectra that the trapped- and the averaged-valence states coexist at higher temperatures and the relative areal intensity of the averaged-valence state increases with an increasing temperature. An abrupt increase of the relative areal intensity above 180 K suggests that an intermolecular effect on the mixed-valence state changes at the temperature.

Authors: Asakura Kiyotaka , Iwasawa Yasuhiro 
Published: July 2006

Abstract
While platinum supported on one-atomic layer Niobium oxide which was chemically attached on a silica surface did not exhibit an SMSI phenomenon unlike usual Nb2O5-supported Pt, the ethene hydrogenation activity of the catalyst reduced at 773 K was much higher than a SiO2-supported Pt catalyst. Another interesting feature is that the activity was reversibly enhanced or depressed as a function of pre-evacuation temperature.
