Radiolytic Oxidation of Ruthenium Oxide Deposits

Nuclear Technology, 2008
AbstractIn the case of a hypothetical severe accident in a nuclear pressurized water reactor, the formation of radiotoxic RuO4(g) may occur in the reactor containment building, resulting from the interactions of ruthenium oxide deposits with the oxidizing medium induced by air radiolysis.

Oxidative Dehydrogenation of Ethylenediamine Coordinated to Ruthenium with Hexafluoroacetylacetonate, Induced by Electrochemical Oxidation of Ruthenium(II) to Ruthenium(III)

Bulletin of the Chemical Society of Japan, 1992
Abstract Two mixed-ligand complexes, [Ru(hfac)2(en)] and [Ru(hfac)(en)2]PF6 (en = ethylenediamine and hfac− = hexafluoroacetylacetonate ion), were synthesized. The oxidative dehydrogenation of their en ligand was studied in acetonitrile solutions. Each complex underwent a Nernstian one-electron oxidation at platinum electrodes.

Electrochemical Capacitors Using Hydrous Ruthenium Oxide and Hydrogen Inserted Ruthenium Oxide

Journal of The Electrochemical Society, 1998
Electrochemical capacitors made with hydrous ruthenium oxide and hydrogen inserted hydrous ruthenium oxide electrode materials were investigated. The electrochemical behavior of in the potential range of −0.2 to 1.3 V vs. saturated calomel electrode (SCE) was characterized using a cyclic voltammetry technique.

Ruthenium as an Effective Nitric Oxide Scavenger

Current Topics in Medicinal Chemistry, 2004
Whilst nitric oxide (NO) has emerged as one of the most versatile and ubiquitous molecules in the human body with a diverse range of physiological functions, dysfunction in NO biosynthesis or metabolism has led to the pathogenesis of a number of disease states.

Ruthenium-Catalyzed Oxidation of Alcohols into Amides

Organic Letters, 2009
The synthesis of secondary amides from primary alcohols and amines has been developed using commercially available [Ru(p-cymene)Cl(2)](2) with bis(diphenylphosphino)butane (dppb) as the catalyst.

Fast and Durable Alkaline Hydrogen Oxidation Reaction at the Electron‐Deficient Ruthenium–Ruthenium Oxide Interface

Advanced Materials, 2023
AbstractThe slow hydrogen oxidation reaction (HOR) kinetics under alkaline conditions remain a critical challenge for the practical application of alkaline exchange membrane fuel cells. Herein, Ru/RuO2 in‐plane heterostructures are designed with abundant active Ru–RuO2 interface domains as efficient electrocatalysts for the HOR in alkaline media.

Oxidative Dimerization of Aryldiynyl–Ruthenium Complexes

Organometallics, 2012
Chemical oxidation of Ru(C≡CC≡CR)(dppe)Cp with [FeCp2]PF6 affords the binuclear cations [{Ru(dppe)Cp}2C8R2]2+(PF6–)2 (R = Ph, 72+(PF6–)2; R = Fc, 82+(PF6–)2) by radical coupling at electron-rich sites involving the inner and outer C≡C triple bonds, to give cyclobutenediylidene derivatives.

Ruthenium‐Catalyzed Aerobic Oxidation of Amines

Chemistry – An Asian Journal, 2018
AbstractAmine oxidation is one of the fundamental reactions in organic synthesis as it leads to a variety of value‐added products such as oximes, nitriles, imines, and amides among many others. These products comprise the key N‐containing building blocks in the modern chemical industry, and such transformations, when achieved in the presence of ...

Catalytic Oxidations Using Ruthenium Porphyrins.

ChemInform, 2003
The major goal of the Chapter is to review developments in the use of Ru-porphyrin complexes as homogeneous (or matrix-supported) catalysts for oxygenation and oxidation processes. The subject was given impetus with the discovery of a remarkable reaction in which a Ru(II) porphyrin complex reacted with O2 to give a trans-dioxo-Ru(VI) species.
