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.

Nitric oxide-releasing ruthenium nanoparticles

Chemical Communications, 2011
Nitric oxide-releasing ruthenium nanoparticles were synthesized by the reaction of alkanethiolate-protected ruthenium nanoparticles with tert-butyl nitrite ((t)BuONO), and their water-soluble derivatives are able to deliver NO to proteins such as reduced myoglobin upon light irradiation in aqueous 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 ...

Oxidative Dimerization of Arylalkynyl–Ruthenium Complexes

Organometallics, 2011
Chemical oxidation of Ru(C≡CPh)(PPh3)2Cp with [FeCp2]PF6 affords the binuclear cationic complexes [Cp(PPh3)2Ru{═C═CHC6H4CPh═C═}Ru(PPh3)2Cp](PF6)2 (2) and [Cp(PPh3)2Ru{C≡C(C6H4)CPh═C═}Ru(PPh3)2Cp]PF6 (3) by radical coupling at sites shown to be electron-rich by DFT studies, particularly involving the acetylide Cβ and Ph Cpara atoms and, to a lesser ...

Characterization and dissolution properties of ruthenium oxides

Journal of Colloid and Interface Science, 2011
Ruthenium oxides (RuO(2)·1·10H(2)O and RuO(2)) have been synthesized by forced hydrolysis and oxidation of ruthenium chloride. The resulting materials were extensively characterized to determine the crystallinity, surface area, and ruthenium oxidation state.

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.

Characterization of Tantalum Oxide–Ruthenium Oxide Hybrid Capacitors

IEEE Transactions on Industrial Electronics, 2004
The ac and dc performance and leakage current of Evans tantalum oxide-ruthenium oxide hybrid capacitors were characterized at room temperature. The RC time constants were in the range from 2 to 0.45 ms and dependent on the maximum operational voltage of the capacitor.
