1. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach
Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

2. Photoredox Catalysis Driven by Visible Light and Iron N-Heterocyclic Carbene Complexes
Abstract : Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. READ MORE

3. Homogeneous and heterogeneous Cp*Ir(III) catalytic systems : Mechanistic studies of redox processes catalyzed by bifunctional iridium complexes, and synthesis of iridium-functionalized MOFs
Abstract : The purpose of this doctoral thesis is to investigate and develop catalytic processes mediated by iridium(III) complexes. By understanding the mechanisms, the weaknesses of the designed catalysts can be identified and be overcome in the following generation. READ MORE

4. Iridium Catalyzed Carbon- Heteroatom Bond Forming Reactions via Hydrogen Transfer : Method Development and Mechanistic Elucidations
Abstract : The present thesis describes the applicability of two different iridium(III) complexes for C-O and C-N bond forming reactions. The different projects described in this work are united by the use of an iridium catalyst bearing a functionalized N-heterocyclic carbene ligand. READ MORE

5. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application
Abstract : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. READ MORE
