Synthetic Models for Dizinc Metallohydrolases by Simone Wöckel( )
2 editions published in 2011 in English and held by 16 WorldCat member libraries worldwide
This work presents the synthesis and characterisation of new binuclear zinc complexes that mimic the active sites of dizinc metallohydrolases. To emulate the three-dimensional protein scaffolds of these enzymes, a pyrazole based ligand is used that is substituted in positions 3 and 5 with chelating side chains. Bearing aromatic donor groups, side chains containing imidazole and benzimidazole moieties are a common motif to mimic histidine. In addition, carboxylate groups are used to emulate aspartate. Complexation of the designed ligands with zinc leads to the synthetic analogues of the active sites of the above mentioned enzymes. In the course of complex synthesis, a comprehensive investigation of complexes based on the ligand that bears imidazole as chelating side chains is reported. The coordination chemistry of this ligand is studied by potentiometric titrations. Depending on the pH, six different species are determined in solution and four of them are isolated in solid state and characterised by X-ray diffraction
High-field EPR and ENDOR spectroscopy for proton-coupled electron transfer investigations in E.coli ribonucleotide reductase by Tomislav Argirevic( )
2 editions published between 2011 and 2012 in English and held by 14 WorldCat member libraries worldwide
Ribonucleotide reductases (RNRs) catalyze the conversion of nucleotides to deoxynucleotides in all organisms, thereby providing the essential precursors for DNA synthesis and replication. The E.coli RNR is composed of two homodimeric subunits: alpha2 and beta2. In alpha2 nucleotides are converted to deoxynucleotides and beta2 contains a stable di-iron tyrosyl radical (Y122) cofactor. A proton-coupled electron transfer (PCET) mechanism is proposed to occur over a distance of more than 35 Å originating from Y122 and ending up in the generation of a C439 in alpha2 which in turn initiates the nucleotide reduction process. Three conserved redox-active tyrosines (beta2-Y356, alpha2-Y730 and alpha2-Y731) are essential for the radical transfer to Cys439 and are proposed to be connected through hydrogen- bonds during reversible charge migration over both subunits. In order to probe for structural and mechanistic requirements of a PCET event in alpha2, NH2Y has been incorporated through the suppressor tRNA/aminoacyl-tRNAsynthetase methodology at positions 730 and 731, respectively

Metal complexes of Scorpionate-Like Polyimido Sulphur Phosphanyl Ligands by Margret Meinholz( )
1 edition published in 2011 in English and held by 14 WorldCat member libraries worldwide
In this thesis a new synthetic access to side-arm functionalized sulphur diimide ligands is developed. They can be tuned in their steric demand as well as in their electronic properties. Thus, this new ligand class shows outstanding performance in terms of ligand design. It can be adapted to accommodate the metal of choice and can stabilise metal cations like Co(II) and Fe(II) in low oxidation states. It becomes evident, that the side-arm has not as much influence on the coordination motif as the sulphur diimide moiety. As the SN2-chelating group is the structural anchor, the variation of the side-arm is almost without limits
Synthesewege zu neuen Mehrkernkomplexen von Pyrazol-NHC-Hybridliganden mit Übergangsmetallen - mit Fokus auf Silber-Komplexe by Maria Georgiou-Smith( )
2 editions published between 2010 and 2011 in German and held by 13 WorldCat member libraries worldwide
Gezieltes Ligandendesign gewinnt in der chemischen Forschung immer mehr an Bedeutung. Es existiert eine Vielzahl an Liganden, die sich am Rückgrat, in der Art und Anzahl ihrer Donoratome sowie den gebundenen Substituenten an den Donoratomen unterscheiden. Die Unterklasse der N-heterozyklischen Carbene (NHCs) eignet sich hervorragend als Ligand für die Komplexsynthese und wurde zu diesem Zweck eingeführt. Das Pyrazol stellt aufgrund seiner vielseitigen Funktionalisierbarkeit ein ideales Basismolekül für die Ligandsynthese dar. Unter Verwendung dieser Grundbausteine konnten im Rahmen dieser Arbeit mehrere Pyrazol-NHC-Hybridliganden mit unterschiedlichen arylischen und aliphatischen Substituenten synthetisiert werden. Ziel dieser Arbeit war es, Übergangsmetall-Komplexe mit diesen NHC-Liganden zu synthetisieren. Silber-NHC-Komplexe sind nicht nur als Carbentransfer-Reagenzien verwendbar, sondern sind selbst aufgrund ihrer oft ungewöhnlichen strukturellen und optischen Eigenschaften von Interesse. Sie liegen oft als mehrkernige Aggregate vor. Komplexe der Zusammensetzung [(Lx)2Ag4]2+ konnten aus der Reaktion zwischen dem jeweiligen Liganden [H3Lx](X)2 mit Silber(I)oxid in Acetonitril erhalten werden. Über Transmetallierungsreaktionen mit Palladiumsalzen konnten die Pyrazol-NHC-Hybridliganden an Palladium koordiniert werden

Organometallic Oxidation Catalysis. Topics in Organometallic Chemistry, Volume 22 ( )
1 edition published in 2007 in English and held by 6 WorldCat member libraries worldwide
Eighty per cent of all compounds produced in the chemical and pharmaceutical industries require at least one essential catalytic step during their synthesis. At the same time, the use of hydrocarbons as a feed-stock for commodity and fine chemicals typically requires an oxidation step, which is usually mediated by a transition metal compound. Consequently, oxidation catalysis is a major research field in chemistry, both in academia and in industry. In many such processes, species with metal-carbon bonds are formed as key intermediates, and these processes represent the primary focus of this volume. An important aspect covered by some of the expert contributors is the use of organic ligands - and thus organometallic complex metal fragments - to achieve efficient oxidation catalysis.; It has not been self-evident that organometallic complexes can survive the conditions necessary for polar oxygen-transfer reactions, but research over the last decade concerning oxo and peroxo complexes functionalized by organic ligands has clearly shown that relatively non-polar M-C bonds can be quite stable in the presence of oxidants and protic media, and that they may even be essential for the favourable activity and life-time of a catalyst. Also considered in this context is the oxidation chemistry of basic organometallic species in the gas phase, as this may reveal fundamental characteristics inherent to oxidation catalysts
