Organometallic oxidation catalysis( Book )

2 editions published in 2007 in English and held by 93 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
Controlled folding and conformational switching in metal-mediated DNA constructs by Fernanda Antonia Pereira( )

2 editions published between 2016 and 2017 in English and held by 16 WorldCat member libraries worldwide

The work here presented explores DNA as a potential tool for supramolecular nanoconstructs, controlled self-assembly and the easy synthesis and manipulation of the DNA. Besides this, the introduction of chemical modifications to DNA is presented, which opens up possibilities of several applications such as charge transfer, nanomagnets, catalysis and many more. Important contributions were given and explored by the incorporation of artificial nucleobases and groups into DNA through the solid phase synthesis, where the formation of artificial metal-base pairing in recent years has brought sev
Supramolecular coordination cages based on bispyridyl-ligands with redox properties by Marina Versäumer( )

2 editions published in 2016 in English and held by 16 WorldCat member libraries worldwide

This thesis explores the self-assembly, the host-guest chemistry and the redox behavior of novel coordination double-cages based on organic bispyridyl ligands and Pd(II) metal ions. The formation of these double-cages depends on the interplay of many factors, such as solvent, temperature, metal coordination sites, length and shape of ligands, counter anions and guest molecules. These new three-dimensional architectures with nanoscopic size are of special interest for numerous potential applications, in particular for usage as molecular sensors, as nanoreactors or in photoelectronic devices
Structure, Mechanism and Inhibition of the human Glutaminyl Cyclase by Oliver Kupski( )

2 editions published between 2016 and 2017 in English and held by 16 WorldCat member libraries worldwide

The mammalian zinc-dependent enzyme glutaminyl cyclase (QC, EC belongs to the family of transferases and plays a crucial role in hormone maturation by cyclizing irreversibly N-terminal glutamines post-translationally to pyroglutamic acid (5-oxo-L-proline, pGlu) via a deamidation reaction. Although, the physiological function of pGlu at the N-terminus seems to be essential for generation of biologically active structures, it was reported that QC is also capable to catalyze the intramolecular cyclization of N-terminal glutamic acid precursors via a dehydration reaction, which is dir
Control over assembly and interpenetration of Pd-based coordination cages by Rongmei Zhu( )

2 editions published in 2017 in English and held by 16 WorldCat member libraries worldwide

In the first part, a thermordynamically stable monomeric cage was obtained and the transformation from the monomeric cage to dimeric cage and even to a triple catenane was realized by varying the amount of halide anions. In the second part, a peanut-shape cage and its interpenetration cage were obtained by elongating the backbones. In the last part, two multi-component heteroleptic coordination cages were achieved from two different ligands via side-chain directed complimentary coordination strategy
Development of Zinc-Finger-Based Artificial Restriction Endonucleases and Fluorescent Peptidyl Metal Sensors by Florian Czerny( )

1 edition published in 2016 in English and held by 15 WorldCat member libraries worldwide

Zinc finger proteins are ubiquitous in the cellular environment having an excessive diversity and performing variable tasks. Their outstanding capability to develop a sequence-specific bond to deoxyribonucleic acid (DNA) makes them one of the most abundant DNA-binding domains present in many eukaryotic and prokaryotic transcription factors. The first part of this thesis describes the modification of the zinc finger protein from Zif268 by introducing artificial dinuclear amino acids to establish novel and substantially downsized artificial restriction endonucleases. Furthermore, a phosphose
Ruthenium(II)- and Copper(I)-Catalyzed C-H Functionalizations by Fanzhi Yang( )

1 edition published in 2015 in English and held by 15 WorldCat member libraries worldwide

Transition metal-catalyzed cross-coupling reaction as one of the greatest chemical innovations of 20th century has to utilize stoichiometric amounts of prefunctionalized reagents. In comparison, the transition metal-catalyzed direct C-H functionalization provided a more atom- and step-economical pathway for the synthesis and modification of arenes. Within this thesis, several new synthetic methods based on transition metal-catalyzed C-H functionalization have been developed. Oxidative annulations of alkynes by C-H/N-H cleavages have recently emerged as a useful strategy for the sustainable
Deciphering the Catalytic Mechanism of the Zn Enzyme Glutaminyl Cyclase and the Deduction of Transition-State Analog Inhibitors by Alexander Piontek( )

2 editions published in 2014 in English and held by 15 WorldCat member libraries worldwide

Zn(II)-dependent glutaminyl cyclase (QC) converts N-terminal glutamine or glutamate residues of peptides and proteins. The reaction product is in both cases N-terminal pyroglutamic acid (pyroGlu). In animals the glutaminyl cyclization is involved in posttranslational modification and activation of peptide-based hormone and chemokine precursors. Recently it was established that the driving force in neurodegenerative processes is the pyroGlu modification at the N-terminus of A[beta] peptides processed by QC. This unveils the inhibition of QC as a strategy in AD treatment. The enzyme-specific inhib

N2 splitting and functionalization in the coordination sphere of rhenium by Isabel Christina Klopsch( )

2 editions published in 2016 in English and held by 15 WorldCat member libraries worldwide

The first example of homogeneous N2 splitting mediated by rhenium as group 7 transition metal is reported and represents rare complete scission of the N-N bond in well-defined terminal nitrido complexes. These could be alkylated with electrophiles to imido complexes. Further functionalizations transform the nitrogen containing moeity into organonitriles under recovery of the starting material. Therefore, a synthetic cycle for the transformation of N2 into nitriles comprising three reaction steps is closed. Synthesis, characterization and reactivity of all involved complexes is presented
C2-Symmetric Pyrazole-Bridged Ligands and Their Application in Asymmetric Transition-Metal Catalysis by Torben Böhnisch( )

1 edition published in 2016 in English and held by 15 WorldCat member libraries worldwide

Within the scope of this thesis the synthesis of a plethora of examples of in total three types of C2-symmetric pyrazole-bridged ligand systems (namely PyrBOX, PyrBPyBOX and ProPyrazole) could be established (Chapter 4). Subsequently, the PyrBOX ligands proofed to be versatile ligands for asymmetric allylic substitution reactions (Chapter 7). Starting from three different palladium allyl precursors and four PyrBOX ligands in total twelve different complexes could be isolated. The investigations of these intermediate dinuclear allyl palladium complexes in solution (e.g., EX
Homo- and Mixed-valence [2 x 2] Grid Complexes by Jin Tong( )

2 editions published in 2016 in English and held by 15 WorldCat member libraries worldwide

In this work homo- and mixed-valence [2 x 2] grid-like complexes were studied in detail. Here, the multifunctionality features of these iron and cobalt grids are clearly illustrated in properties: 1) the electrochemistry of the metal centers and ligands, which provide a range of redox levels; 2) the magnetism of metal centers, in which the spin state may be influenced not only by the substitution of ligands but also by the structure of complexes; 3) the redox processes are able to change not only the oxidation state but also the spin state of the metal centers, which can enrich the functio

Two-in-one Pincer Type Ligands and Their Metal Complexes for Catalysis by Alexander Gers-Barlag( Book )

2 editions published in 2017 in German and held by 2 WorldCat member libraries worldwide

The synthesis, characterization and first applications in catalysis of dinuclear metal complexes of the new Two-in-one pincer ligand scaffold are described in this work. Zinc(II) compexes were used to compare structural and electronical features of two derivatives of the ligand system. Reactivity studies revealed a broad range of reactions for a cobalt(II) complex, although detailed analysis of the reaction products was not possible so far. Furthermore, several rhodium(I) complexes have been synthesized and fully characterized. For a rhodium(I) carbonyl complex a dearomatization sequence wa
Design and Characterisation of Multifunctional Tools for the Elucidation of the Cu+ Chemistry in Alzheimer's Disease by Markus Rittmeier( )

1 edition published in 2013 in English and held by 2 WorldCat member libraries worldwide

Alzheimer's disease is the most common neurodegenerative disease in the world. Alzheimer's disease is clinically characterised by decreased cognitive performance and pathologically characterised by formation of fibrillar amyloid plaques, so called A[beta]-plaques and neurofibrillary tangles, which are aggregated tau proteins. It was first described by the German physician Alois Alzheimer in 1906. Even after 100 years, no therapies are available which can cure the disease or stop its progression. Current drugs only alleviate the symptoms and even this is strongly limited. Reason for the lack of e
Synthetic Models for Dizinc Metallohydrolases by Simone Wöckel( )

1 edition published in 2011 in English and held by 2 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
Neue unsymmetrische Pyridazin-verbrückte Pyrazol/NHC-Hybridliganden als Gerüste für multinukleare Übergangsmetallkomplexe - erste Anwendungen in der Katalyse by Jan Wimberg( )

1 edition published in 2012 in German and held by 2 WorldCat member libraries worldwide

The synthesis and characterization of pyridazine-bridged NHC/pyrazole ligands providing an NHC as organometallic and a classical N-donor compartment is described. These ligands serve as versatile scaffolds for a variety of homo- and heterometallic silver (I), gold(I) and palladium (II) carbene complexes. The main focus of the dissertation is on the characterization of these complexes through various spectroscopic methods and on the examinations regarding their first possible applications
