Ruthenium red, [ (NH 3) 5 Ru-O-Ru (NH 3) 4 -O-Ru (NH 3) 5] 6+, is a biological stain used to stain polyanionic molecules such as pectin and nucleic acids for light microscopy and electron microscopy. [64] The beta-decaying isotope 106 of ruthenium is used in radiotherapy of eye tumors, mainly malignant melanomas of the uvea. [65]
This initial ruthenium catalyst was followed in 1995 by what is now known as the first-generation Grubbs catalyst. It is synthesized from RuCl 2 (PPh 3) 3, phenyldiazomethane, and tricyclohexylphosphine in a one-pot synthesis. [8][9] The first-generation Grubbs catalyst was the first well-defined Ru-based catalyst.
Organoruthenium chemistry is the chemistry of organometallic compounds containing a carbon to ruthenium chemical bond. Several organoruthenium catalysts are of commercial interest [ 1] and organoruthenium compounds have been considered for cancer therapy. [ 2] The chemistry has some stoichiometric similarities with organoiron chemistry, as iron ...
Ru 3 (CO) 12 + n L → Ru 3 (CO) 12-n L n + n CO (n = 1, 2, or 3) where L is a tertiary phosphine or an isocyanide. It forms complexes with acenaphthylene. [7] Ru 3 (CO) 12 forms a variety of alkene complexes, some where the Ru3 core remains intact but often with fragmentation. Upon treatment with 1,5-cyclooctadiene gives the monoRu tricarbonyl ...
Ruthenium compounds are compounds containing the element ruthenium (Ru). Ruthenium compounds can have oxidation states ranging from 0 to +8, and −2. The properties of ruthenium and osmium compounds are often similar. The +2, +3, and +4 states are the most common. The most prevalent precursor is ruthenium trichloride, a red solid that is ...
As with all Haber–Bosch catalysts, nitrogen dissociation is the rate-determining step for ruthenium-activated carbon catalysts. The active center for ruthenium is a so-called B5 site, a 5-fold coordinated position on the Ru(0001) surface where two ruthenium atoms form a step edge with three ruthenium atoms on the Ru(0001) surface. [65]
primordial element. synthetic element. Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] ". Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1] It should not be confused with "group VIIIA" in the CAS system ...
Group 8 elements with 8 valence electrons form pentacarbonyls Fe(CO) 5, Ru(CO) 5 and Os(CO) 5. The heavier two members are unstable, tending to decarbonylate to give Ru 3 (CO) 12, and Os 3 (CO) 12. The two other principal iron carbonyls are Fe 3 (CO) 12 and Fe 2 (CO) 9. Group 9 elements with 9 valence electrons and are expected to form ...
