Authors: Iwata Masaaki , Kuzuhara Hiroyoshi 
Published: May 2006

Abstract
Secondary formamides were found to be favorable sources for the efficient oxygenation site via N-nitrosation. Thermal reaction (85 °C in benzene) of N-nitroso formamides proceeded effectively to provide the corresponding formates in good yields, which, then, were hydrolyzed to alcohols under weakly basic conditions. In treatment of optically active formamide, the corresponding alcohol was isolated with 72% retention of configuration.

Authors: Kijima Masashi , Kato Masahiro , Sato Takeo 
Published: May 2006

Abstract
A new method for investigating the redox behavior of powdery polymer carrying cobaloxime is described. Benzylcobaloxime and chlorocobaloxime are each immobilized into cross-linked poly(4-vinylpyridine). Insoluble polymers soaked in an electrolyte solution are set on a platinum working electrode. The redox behaviors of these cobaloximes were recorded in a solid state by cyclic voltammetry.

Authors: Arai Gorou , Harashina Tomitaka , Yasumori Iwao 
Published: May 2006

Abstract
CO2 was electrochemically reduced to CH3OH in aqueous Na2SO4 solution on a Ru-modified glassy carbon electrode. Ru was fixed on poly(hydroquinone/p-benzoquinone) prepared by electropolymerization of mercaptohydroquinone. The reduction of CO2 proceeded with markedly low overvoltage, starting at −0.5 V vs. SCE at room temperature. The current efficiency for CH3OH formation attained ca. 100% at −0.7 V vs. SCE with a current density of ca. 0.2 mA/cm2.

Abstract
Imidazolate-bridged copper(II)–chromium(III)–copper(II) complex, [Cu(A)Cr(salen)Cu(A)]ClO4·3H2O, has been synthesized and characterized, where H2A = 4-(6-methyl-8-oxo-2,5-diazanona-1,5,7-trienyl)imidazole and H2salen = N,N′-di(salicylidene)ethylenediamine, respectively. The magnetic moment per molecule increases from 4.61 BM at 297.8 K to the maximum value 5.27 BM at 14 K, and then decreases to 4.42 BM at 4.4 K. The magnetic behavior shows that there operates a ferromagnetic interaction between chromium(III) and copper(II) ions through imidazolate group.

57Fe-Moessbauer Spectroscopic Studies of the Ferrocenylruthenocenium+BF4− Salts
Authors: Watanabe Masanobu , Sano Hirotoshi 
Published: May 2006

Abstract
Ferrocenylruthenocene reacts with sulfuric acid-NH4BF4 to give a diamagnetic ferrocenylruthenocenium+BF4− salt, while it reacts with benzoquinone-BF3(Et2O) to give a paramagnetic ferrocenylruthenocenium3+(BF4−)3 salt. Based on the results of 57Fe-Moessbauer spectroscopic studies, the Moessbauer parameters of the former salt are very similar to those of neutral ferrocenylruthenocene, suggesting that the structure of the salt is assumed to be [Cp(C5H4)Fe(C5H4)CpRu–RuCp(C5H4)Fe(C5H4)Cp]2+(BF4−)2 in the solid state.

Influence of the Carbon Backing Paper on Oxygen Reduction Parameters in Phosphoric Acid Fuel Cell Electrodes
Authors: Watanabe Masahiro , Stonehart Paul , Inoue Mikio , Fukui Hiroaki , Miwa Kishio 
Published: May 2006

Abstract
Significant diffusion overpotential losses are encountered due to the carbon backing paper alone in phosphoric acid fuel cell electrodes. Above that, the diffusion overpotentials in the electrocatalyst layer are also significant, so gains are still to be made by further reducing both of these diffusion overpotentials. Since the overpotential in the backing paper is proportional to the thickness of the paper, reduction of the thickness is very important for the improvement of the electrode performance.

57Fe-Mössbauer Spectroscopic Studies of Mixed-valence Binuclear Ferrocenes with Various Metal Complex Anions
Authors: Kai Masahiro , Katada Motomi , Sano Hirotoshi 
Published: May 2006

Abstract
Mixed-valence binuclear ferrocenium salts with FeCl4−, SnCl62−, and ZnCl42− anions were studied by using 57Fe-Mössbauer spectroscopy. The FeCl4− and SnCl62− salts show two types of the temperature dependence of the spectra, whereas the ZnCl42− salt shows no temperature dependence, concluding that the valence state of iron atoms does not depend on the chemical nature of binuclear ferrocenyl cations but on the interactions through the cations and the anions in solid.
