Making Oxygen with Ruthenium Complexes

Accounts of Chemical Research, 2009
Mastering the production of solar fuels by artificial photosynthesis would be a considerable feat, either by water splitting into hydrogen and oxygen or reduction of CO(2) to methanol or hydrocarbons: 2H(2)O + 4hnu --> O(2) + 2H(2); 2H(2)O + CO(2) + 8hnu --> 2O(2) + CH(4).

Protonation of a Ruthenium Vinylidene Complex with a NO Ligand Leading to Ruthenium Vinyl Complexes

Organometallics, 2009
Treatment of a ruthenium vinylidene complex bearing a bent-type NO ligand, RuCl(NO)(PPh3)2{═C═CH(C6H4Me)} (1), with protic acids gave rise to the ruthenium vinyl complexes RuCl(X){(Z)-CH═CH(C6H4Me)...

Metal complexes of ruthenium

Anti-Cancer Drugs, 1990
Octahedral ruthenium(III) and ruthenium(II) complexes show antineoplastic properties on a number of experimental tumors. Tetraammine-, pentaammine-, heterocycle-, and dimethylsulfoxide-coordinated ruthenium complexes have shown high affinity for nitrogen donor ligands in vitro and as a result exhibit various degrees of biological activities including ...

Polypyrazolylmethane complexes of ruthenium

Journal of the Chemical Society, Dalton Transactions, 2001
A series of ruthenium(II) complexes with the pyrazolyl alkane ligands tris(1-pyrazolyl)methane 1 (TPM) and bis(1-pyrazolyl)methane 2 (BPM) have been synthesized and characterised. The complex [RuCl(PPh3)2(TPM)]+X (X = Cl 3a or BF43b) was formed by the reaction of TPM with RuCl2(PPh3)3 and [Ru(CO)H(PPh3)(TPM)]+X (X = Cl 4a or BF44b) by the reaction of ...

Cyclopentadienyl-ruthenium and -osmium complexes

Journal of Organometallic Chemistry, 1982
Abstract Ruthenium and osmium complexes of the type CpMX(PPh 3 )L (M = Ru; X = Cl, H, S 2 COC 10 H 19 , S 2 COMe; L & PPh 3 and PHPh 2 ; M = Os, X = Cl, Br, I, H, D, xanthogenate, dithiocarbamate, BPh 4 , L = PPh 3 ). The compound CpOsCl(PPh 3 ) 2 is readily soluble in MeOH and in the solution the cation [CpOs(PPh 3 ) 2 ] + is present.

Ruthenium Complexes as Anticancer Agents

Current Medicinal Chemistry, 2006
Cancer is one of the major cases of death in the world. Current treatment of cancer is limited to surgery, radiotherapy, and the use of cytotoxic agents, despite their well known side effects and problems associated with the development of resistance.

Sulphoxide complexes of ruthenium

Transition Metal Chemistry, 1978
Compounds of the type RuL4−nX2+n where L = dimethyl sulphoxide (DMSO), tetramethylene sulphoxide (TMSO) and X = Cl, Br or I for n = 0 and L = di-n-propyl sulphoxide (n-Pr2SO) and di-n-butyl sulphoxide (n-Bu2SO) X = Cl or Br for n = 1 and also Ru(DMSO)6Br3 have been prepared and studied. The important i.r.

Ruthenium maltolato complexes

Chemical Communications, 1997
Two maltol molecules can be deprotonated and coordinated to Ru II to generate a series of octahedral complexes having the general formula Ru(ma) 2 L 2 (ma = C 6 H 5 O 3 ; L = PPh 3 , Me 2 SO; L 2 = cycloocta-1,5-diene); when L = PPh 3 , a precursor for the dimerization of phenylacetylene is obtained.

Ruthenium complexes with diazadienes

Journal of Organometallic Chemistry, 1987
Abstract The easily accessible diazadieneruthenium carbonyl complexes [(DAD)Ru-(CO) 2 I 2 ] (I, DAD  RNCR′ CR′NR) are photolytically labile and under CO substitution. The reaction can be monitored by UV/VIS spectroscopy and by cyclic voltammetry (CV), in which there are points of constant current and potential analogous to isosbestic points.
