Improving the hydrogen oxidation reaction rate by promotion of hydroxyl adsorption.

Nature Chemistry 5(4) , 300-6, (2013)

The development of hydrogen-based energy sources as viable alternatives to fossil-fuel technologies has revolutionized clean energy production using fuel cells. However, to date, the slow rate of the hydrogen oxidation reaction (HOR) in alkaline environments ...

Si-H activation in an iridium nitrido complex--a mechanistic and theoretical study.

J. Am. Chem. Soc. 135(10) , 3971-82, (2013)

Si-H activation in triethyl- and triarylsilanes by a square-planar pyridine-diimine iridium complex with a terminal nitrido unit leads to the corresponding silyl amido complexes, which were unambiguously characterized by X-ray crystallography. Based on detail...

Steric parameters in the Ir-catalyzed regio- and diastereoselective isomerization of primary allylic alcohols.

Org. Lett. 15(24) , 6170-3, (2013)

The iridium-catalyzed diastereo- and regioselective isomerization of primary allylic alcohols using Crabtree's catalyst or sterically modified analogs is reported. The importance of the size of the substituents on either the substrates or the catalysts has be...

Rhodium, iridium, copper and gold antitumor organometallic compounds (review).

In Vivo 3(4) , 285-93, (1989)

Recent results on the antitumor activity of organometallic compounds of rhodium, iridium, copper and gold are reviewed. Coordination compounds of some organic ligands are also briefly mentioned. The most promising seem to be copper and gold complexes which ex...

DNA binding and anti-cancer activity of redox-active heteroleptic piano-stool Ru(II), Rh(III), and Ir(III) complexes containing 4-(2-methoxypyridyl)phenyldipyrromethene.

Inorg. Chem. 52(7) , 3687-98, (2013)

The synthesis of four novel heteroleptic dipyrrinato complexes [(η(6)-arene)RuCl(2-pcdpm)] (η(6)-arene = C6H6, 1; C10H14, 2) and [(η(5)-C5Me5)MCl(2-pcdpm)] (M = Rh, 3; Ir, 4) containing a new chelating ligand 4-(2-methoxypyridyl)-phenyldipyrromethene (2-pcdpm...

Dicarba-closo-dodecarborane-containing half-sandwich complexes of ruthenium, osmium, rhodium and iridium: biological relevance and synthetic strategies.

Chem. Soc. Rev. 41(8) , 3264-79, (2012)

This review describes how the incorporation of dicarba-closo-dodecarboranes into half-sandwich complexes of ruthenium, osmium, rhodium and iridium might lead to the development of a new class of compounds with applications in medicine. Such a combination not ...

Peptide-tethered monodentate and chelating histidylidene metal complexes: synthesis and application in catalytic hydrosilylation.

Dalton Trans. 42(16) , 5655-60, (2013)

The Nδ,Nε-dimethylated histidinium salt (His*) was tethered to oligopeptides and metallated to form Ir(III) and Rh(I) NHC complexes. Peptide-based histidylidene complexes containing only alanine, Ala-Ala-His*-[M] and Ala-Ala-Ala-His*-[M] were synthesised ([M]...

In vitro study of iridium electrodes for neural stimulation.

Conf. Proc. IEEE Eng. Med. Biol. Soc. 2012 , 819-22, (2012)

Iridium is one of the main electrode materials for applications like neural stimulation. Iridium has a higher charge injection capacity when activated and transformed into AIROF (activated iridium oxide film) using specific electrical signals. Activation is n...

Intrinsic activation of iridium electrodes over a wireless link.

Conf. Proc. IEEE Eng. Med. Biol. Soc. 2012 , 2788-91, (2012)

Activated Iridium Oxide Film (AIROF) microelectrodes are regarded as advantage for stimulation of neural tissue owing to their superior charge injection capabilities, as compared to other noble-metal based electrodes. Including AIROF electrodes within an impl...

Luminescent biscarbene iridium(III) complexes as living cell imaging reagents.

Chem. Commun. (Camb.) 49(31) , 3230-2, (2013)

Five iridium(III) complexes with two N-heterocyclic carbene (NHC) ligands and an ancillary ligand have been designed and successfully synthesized. With multicolor photoluminescence and low toxicity, these carbene complexes were tested, for the first time, as ...
