A miniaturized polymer electrospray-type interface is used to study metal-ion chelation with model peptides. Taking advantage of the intrinsic electrochemical behavior of electrospray, a sacrificial electrode is used to generate at the same time electrospr ...

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 ...

Three immobilized Cu(II) complexes were generated by the following: (a) homopolymerization of the N,N',N '' chelate ligand tris[2-(1-vinylimidazolyl)]phosphine (1) and subsequent metalation with CuCl2; (b) copolymerization of 1 with ethyleneglycol dimethac ...

Ru(II) and Os(II) p-cymene dichloride complexes with either a pta (1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) or [pta-Me]Cl ligand which exhibit anticancer activity were prepd. and characterized by 1H and 31P NMR spectroscopy and mass spectrometry. Thr ...

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 ...

This paper focuses on the mechanism by which a monoterpene undergoes a cyclocarbonylation reaction catalysed by a palladium complex. Evidence is provided, based on intermediate species observed under pressure or with various ligands, that the catalytic cyc ...

A facile pathway to [RuCl2(η6-benzocrownether)]2 complexes is described and crystal structures of the complexes [RuCl2(η6-benzo-15-crown-5)]2 and [RuCl2(η6- ...

Four tetracatenar (L1–L4) and one hexacatenar (L5) ligands, derived from the diaza-18-crown-6 framework, are synthesized and characterized. In these ligands, the amine functions are fitted with benzoyloxybenzyl linker groups, attached either with a carbony ...

Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these complexes can be prepared in pure form in ...

A compound, in metal-free or metal complex form of formula (1) to (3) in which R is hydrogen or C1-30 alkyl; X is hydrogen, halogen (preferably Cl or Br) or C1-30 alkyl. ...

The present invention relates to a new family of mono, bis or tris (2,2'-substituted bipyridine) complexes of a metal selected amongst iron, ruthenium, osmium or vanadium, the bipyridine being substituted by at least one electron donor group. According to ...
