Ruthenium Catalyzed Selective Hydroboration of Carbonyl Compounds
Organic Letters, 2015Using the [Ru(p-cymene)Cl2]2 (1) complex, catalytic hydroboration of aldehydes and ketones with pinacolborane under neat and mild conditions is reported. At rt, chemoselective hydroboration of aldehydes over the ketones is also attained. Mechanistic studies confirmed the immediate formation of monohydride bridged dinuclear complex [{(η(6)-p-cymene)RuCl}

Detection and neutralisation of heparin by a fluorescent ruthenium compound
Thrombosis and Haemostasis, 2009SummaryHeparin and low-molecular-weight heparin (LMWH) are commonly monitored by determination of activated clotting times or chromogenic assays. Despite their wide use, these assays determine the biological activity and not the concentration of the anticoagulants. They may be inaccurate in some circumstances such as certain disease states. In addition,

An XPS study on ruthenium compounds and catalysts
Materials Chemistry and Physics, 1991Abstract The binding energy (BE) of the relevant peaks of several ruthenium compounds have been measured with a monochromatic small spot XPS. The BE of the 3d 5 2 level of ruthenium is in the range 279.91–282.88 eV. The variation of BE is due either to the variation of the oxidation state or to the different counter-ion.

Reflections on osmium and ruthenium carbonyl compounds
Journal of Organometallic Chemistry, 1995Abstract The development of transition metal cluster chemistry is traced from the early discoveries of metal-metal bonded systems through to some recent developments made in the area of high nuclearity osmium and rutherium cluster carbonyls. Emphasis is placed on developments made in the physical techniques used to establish the structures of the ...

Ruthenium compounds in cancer therapy
1994The examination of the biological roles of ruthenium complexes as well as the possibility of producing ruthenium-based drugs, active in the treatment of human malignancies, is believed to have begun with the discovery of the antineoplastic activity of cis-dichlorodiammine platinum(II) (hereafter called cisplatin).
