Atomic layer deposition of metal and metal chalcogenide thin films and nanolaminate composites.
(2018-04-09)The construction of a novel “hot and cold wall, cross laminar flow multiple substrate atomic layer deposition reactor” is presented including a LabView based control program and an user-optimized graphical user interface. ... -
Cobalt-Catalyzed Olefin Hydrogenation
(2023-08-04)This thesis describes the synthesis and isolation of the cobalt complexes, using PNP-pincer ligand system with tert-butyl substituents. The neutral and cationic cobalt hydrides were further probed in olefin hydrogenation ... -
Cooperative (De-)Hydrogenation of Small Molecules
(2019-01-25)Ammonia borane dehydrocoupling to mainly linear polyaminoborane is reported at room temperature using a bifunctional iron catalyst. Mechanistic studies suggest that both hydrogen release and B−N coupling are metal-catalyzed ... -
Electrochemical Dinitrogen Splitting and Nitride Transfer to Nitric Oxide with Rhenium Pincer Complexes
(2022-04-26)The Haber-Bosch process for the synthesis of ammonia from nitrogen and hydrogen consumes large amounts of energy and additionally relies on fossil feedstocks for the production of hydrogen. Alternative approaches for the ... -
Electrochemical N2-splitting and functionalisation in the coordination sphere of Rhenium
(2021-07-13)This thesis describes the exchange of stoichiometric, wasteful chemical redox-reagents with electrochemical activation methods within a rhenium-mediated N2-splitting and functionalisation cycle. After establishing ... -
Metal-Nitrogen Multiple Bonds with Square-Planar Group 9 Transition Metal PNP Pincer Complexes
(2014-11-26)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 ... -
N2 Fixation by Chromium and Rhenium PNP Pincer Complexes
(2022-03-16)This thesis focusses on the activation and functionalization of atmospheric dinitrogen by chromium and rhenium based transition metal complexes. The electronic structure of dinitrogen bridged key species is discussed based ... -
N2 Splitting and Functionalization in the Coordination Sphere of Rhenium
(2017-01-12)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 ... -
N2 Splitting and Functionalization in the Coordination Sphere of Tungsten
(2020-12-02)The splitting and functionalization of N2 remains one of the most challenging reactions in coordination chemistry. In this thesis a series of four isostructural end-on N2 bridged ditungsten-PNP-pincer complexes are synthesized ... -
Proton Coupled Electron Transfer at Heavy Metal Sites
(2021-01-14)Terminal, late transition metal, oxo complexes are pivotal intermediates in oxygenation chemistry. This thesis describes the synthesis and full characterisation of an open-shell terminal oxo complex of iridium from the ... -
Proton-Coupled Electron Transfer at Nickel Pincer Complexes
(2019-05-24)The influence of metal coordination on carbon-centered proton-coupled electron transfer processes is an attractive field of research. Reported literature is limited to thermodynamic investigations and substrate oxidation ... -
Rhenium Mediated Formation of N-Containing Organic Compounds by Nitride Transfer
(2023-01-26)N-containing organic compounds occur in all the organisms, such as in the form of amino acids (and thus proteins), nucleic acids (DNA and RNA), and in the form of energy transfer molecule adenosine triphosphate. The human ... -
Synthesis of Terminal Transition Metal Pnictide Complexes by Activation of Small Molecules
(2019-08-13)Coordination compounds involving metal-nitrogen bonds are a well-developed class of organometallic chemistry. In contrast, the chemistry of the heavier analogues of nitrogen, e.g. phosphorus and arsenic is far less explored. ... -
Transient and Stable Terminal Imido Complexes of Iridium
(2019-07-02)In conclusion, it has been demonstrated that the proton coupled oxidation of metal-bound amines and water provide access to a wide range of imido- and oxo-complexes, respectively. The synthetic approach of using strict 1 ...
