Synthèses, structures et applications catalytiques de nouveaux complexes polynucléaires

Sébastien Gauthier

Various methods for the synthesis of bimetallic complexes, in which two different metal fragments which are connected by two or three halogeno bridges, are reported. The reactions are usually fast and give rise to structurally defined products in quantitat ...

High-Voltage Sensitivity Studies of Model Thick-Film Resistors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Niklaus Johner, Adrian Kambli

In this work we seek to better understand the mechanisms governing pulse voltage trimming in disordered conductor-insulator composites. Therefore, we investigate the effect of the composition of thick-film resistors (TFRs) on sensitivity to high voltage pu ...

The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...

Rational design of organo-ruthenium anticancer compounds

Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens

Organometallic ruthenium(II)-arene complexes are currently attracting increasing interest as anticancer compds. with the potential to overcome drawbacks of traditional drugs like cisplatin with respect to resistance, selectivity, and toxicity. Rational des ...

Syntheses and Structures of the Trinuclear Ruthenium Complexes [RuCl2(PAd2Bu)]3 and [RuCl2(PtBu2Cy)]3

Rosario Scopelliti, Kay Severin, Sébastien Gauthier

The trinuclear Ru complexes [RuCl2(PAd2Bu)]3 (1) and [RuCl2(PtBu2Cy)]3 (2) were obtained by reaction of [(p-cymene)RuCl2]2 with 2 equiv of the resp. sterically demanding phosphine. Crystallog. analyses of 1 and 2 show that the three metal fragments are con ...

The synthesis and characterisation of bis(phosphane)-linked (eta(6)-p-cymene)ruthenium(II)-borane compounds

Paul Joseph Dyson

The reaction of [(η6-p-cymene)RuCl2]2 with some bis(phosphane) ligands (dppm, dppe, dppv, dppa, dpp14b, dppf) has been investigated. In general mixtures of products were obtained, although the pendant phosphane complexes [( ...

The thermochem. of the RuO42- + MnO4- RuO4- + MnO42- redox reaction in aq. soln. is studied by sep. d.-functional-based ab initio mol.-dynamics simulations of the component half reactions RuO42- -> RuO4- + e- and MnO42- -> MnO4- + e-. We compare the result ...

Supramolecular triruthenium cluster-based benzene hydrogenation catalysis: Fact or fiction?

Gabor Laurenczy

The question is addressed of whether the triruthenium cluster cation Ru-3(mu(2)-H)(3)(eta(6)C(6)H(6))(eta(6)-C6Me6)(2)(mu(3)-O), 1, is a supramolecular, outer-sphere benzene hydrogenation catalyst or is 1 a precatalyst to well-known Ru(0)(n) catalysis ...

Cobalt-Catalyzed Hydroazidation of Olefins: Convenient Access to Alkyl Azides

Jérôme Waser

Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetrame ...

Pendant-bridging-chelating-cleavage: A series of bonding modes in ruthenium(II)-BINAPO complexes

Paul Joseph Dyson, Kevin Hänni

Reaction of 1,1'-bis(diphenylphosphino)binaphthol (BINAPO, 1) with [RuCl2(η6-arene)]2 in methanol leads to dinuclear BINAPO-bridged Ru compounds [{RuCl2(η6-p-cymene)}2-(μ-BINAPO)], 2a, in ne ...
