Organometallic oxidation catalysis by Franc Meyer( Book )

14 editions published in 2007 in English and held by 112 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
Neue unsymmetrische Pyridazin-verbrückte Pyrazol/NHC-Hybridliganden als Gerüste für multinukleare Übergangsmetallkomplexe - erste Anwendungen in der Katalyse by Jan Wimberg( )

3 editions published between 2012 and 2013 in German and held by 31 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
Liganden mit N/S-Donorsets in der Münzmetallchemie: Modellkomplexe für Methanobactin und multinukleare, lumineszierende Pyrazolat-Komplexe by Ann Christin Jahnke( )

3 editions published between 2012 and 2013 in German and held by 31 WorldCat member libraries worldwide

The xynthesis and characterization of pyrazolate and oxazolone ligands with attached thioether functions is described. These ligands were used either to synthesize copper(I) complexes as model complex for the methanobactin or to obtain a variety of multinuclear, luminescent coinage metal complexes. The focus of this dissertation is on the characterization of these complexes by various spectroscopic methods and on the investigation regarding their further applications
From X-ray diffraction data annealing to comprehensive charge density analysis by Jakob Hey( )

2 editions published in 2013 in English and held by 30 WorldCat member libraries worldwide

The current thesis focuses on three detailed experimental QTAIM charge density studies on small molecules based on high resolution X-ray diffraction experiments. Each of the three studies required the application of different analytical methods. The first of the studies (chapter 3) deals with the experimentally challenging piano stool complex tris(ammine)cyclopentadienyl sodium. The anticipated highly ionic character of the metalcyclopentadienyl interaction was confirmed by means of the integrated atomic charges and the atomic Source Function contributions in a QTAIM analysis. An out-of-pl

Design and Characterisation of Multifunctional Tools for the Elucidation of the Cu+ Chemistry in Alzheimer's Disease by Markus Rittmeier( )

2 editions published in 2013 in English and held by 24 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
Small Molecule Activation of Copper and Iron Complexes with Bis(oxazoline) Ligands by Vandana Esther Goswami( )

2 editions published in 2017 in English and held by 18 WorldCat member libraries worldwide

This work describes small molecule activation by copper and iron complexes with structurally and electronically modified bis(oxazoline) (BOX) ligand systems, focusing on dioxygen and nitric oxide as substrates. Dioxygen activation at low temperatures by copper(I) complexes with neutral BOX scaffolds generated the side on peroxo dicopper(II) systems that resemble the intermediates found in type III copper proteins, whereas those complexes with an anionic BOX-derived scaffold generated the bis(µ-oxido) dicopper(III) species. The bis(µ-oxido) system has recently been proposed as an active inte
Ruthenium- and Cobalt-Catalyzed Chelation-Assisted C–H Functionalization by Ruhuai Mei( )

2 editions published in 2017 in English and held by 18 WorldCat member libraries worldwide

Catalytic C-H functionalization has emerged as an economically-attractive and environmentally-benign alternative to conventional cross-coupling approaches. Thus, major efforts have been made on transformations of inert C-H bonds into useful functionalities. The work presented within this thesis mainly focused on the development and application of versatile ruthenium- and cobalt-catalyzed direct C-H functionalizations
Two-in-one pincer type ligands and their metal complexes for catalysis by Alexander Gers-Barlag( )

3 editions published between 2016 and 2017 in German and held by 16 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
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
Fluorescence Studies of Amine-substituted Azaanthracene Metal Complexes by Arne Visscher( )

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

Former investigations of the Stalke group focussed on the hydrocarbon fluorophore anthracene. In this thesis, two representatives of the heteroaromatic congener azaanthracene with different fluorescence properties and potential usage as molecular sensors for metal cations were major fields of research. These compounds were 2- and 10-azaanthracene depicted in Figure 1.14, A and B, C, respectively. 2-Azaanthracene is a rare representative in the field of fluorescent sensors. Therefore, a suitable synthesis route for this aromatic system needed to be developed first. Its behaviour towards furt

Construction of low-symmetric and light-switchable coordination cages for guest uptake and catalysis by Muxin Han( )

3 editions published between 2015 and 2016 in English and held by 16 WorldCat member libraries worldwide

An investigation into the self-assembly and the host-guest chemistry of PdII-based metal-organic architectures was presented in this dissertation. In Chapter 2, the formation of an inclusion complex of the hexamolybdate anion [Mo6O19]2- inside a cationic Pd2L4 coordination cage in solution was described. Interestingly, a structure conversion was observed by recrystallization after an excess of hexamolybdate guest was added to the 1:1 inclusion complex. The X-ray structure of {[Mo6O19]@L3+2H} reveals
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

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

The scope of the presented thesis is the realization and detailed analysis of a hybrid system for photoelectrochemical watersplitting with La$_{0.6}$Sr$_{0.4}$MnO$_3$ (LSMO) as photoabsorber and immobilized molecular bis(bipyridyl)pyrazolate diruthenium (Ru$_2$-bbp) catalyst. As a first step towards a full functioning photochemical device, the functionality of the hybrid assembly was elucidated electrochemically since the basic requirements for a photochemical device, such as stability and band alignment need to be also fulfilled for an electrochemical cell. The results herein focused on tw
Metal-Nitrogen Multiple Bonds with Square-Planar Group 9 Transition Metal PNP Pincer Complexes by Markus Scheibel( )

2 editions published in 2014 in English and held by 16 WorldCat member libraries worldwide

Nitrogen is ubiquitous in synthetic and biosynthetic products as an important building block for molecular architecture and functionality. Bimolecular dinitrogen (N2) is its common appearance in nature and is characterized by a strong N-N triple bond and a high kinetic barrier for further conversion. Ammonia as the chemically more accessible nitrogen source is produced under harsh reaction conditions via the Haber-Bosch-process, consuming 1.4% of the global energy. Activation of dinitrogen under ambient conditions is an important goal for industrial and academic research. Cleavage of N2 int
Activation of Nitric Oxide and Dioxygen at Diferrous Complexes with Compartmental Pyrazolate Ligand Scaffolds by Anne Schober( )

This work comprises the synthesis and characterization of novel pyrazolate-bridged bimetallic iron complexes with bis(pentadentate) ligand scaffolds and the activation of dioxygen and nitric oxide at their diferrous sites. It describes the development of two new bridging ligand systems providing two compartments with a fivefold coordination environment for each metal ion. Furthermore, properties of the obtained diferrous complexes were studied by a series of analytical techniques including x-ray diffraction, Mössbauer spectroscopy and temperature dependent UV/Vis spectroscopy. In particular
Der Einfluss von Defekten auf das Schaltverhalten ferroelektrisch modulierter Substanzen by Karsten Behrendt( )

3 editions published between 2015 and 2016 in German and held by 16 WorldCat member libraries worldwide

The influence of defects on the phase transition behavior of A2BX4-compounds was studied by diffraction methods, impedance spectroscopy and atomic force microscopy. It was found that chemical point defects have a strong effect on the transition kinetics, whereas the thermodynamic stability of different modulated phases is only slightly affected by such doping with alkali ions. The lock-in-transition from incommensurate to commensurate modulated is slowed down by several orders of magnitude. The transition time hereby ranges from minutes to months, depending on impurity concentration. Due to
