11. Iron-Catalyzed Reactions and X-Ray Absorption Spectroscopic Studies of Palladium- and Ruthenium-Catalyzed Reactions
Sammanfattning : The focus of this thesis is twofold: The first is on the application of iron catalysis for organic transformations. The second is on the use of in situ X-ray absorption spectroscopy (XAS) to investigate the mechanisms of a heterogeneous palladium-catalyzed reaction and a homogeneous ruthenium-catalyzed reaction.

12. Development of Biomimetic Catalytic Systems for Selective Oxidations with H2O2 and O2
Sammanfattning : Four different catalytic systems were studied for biomimetic coupled oxidations using H2O2 or O2. In the first example, osmium tetroxide works as a substrate-selective catalyst for dihydroxylation of olefins. Electron transfer to H2O2 is facilitated by electron transfer mediators (ETMs). LÄS MER
13. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis
Sammanfattning : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. LÄS MER
14. Biomimetic oxidation methods: Efficient reoxidation of palladium and ruthenium by the use of a hybrid electron transfer catalyst
Sammanfattning : .... LÄS MER
15. Reaction Mechanisms of Metalloenzymes and Synthetic Model Complexes Activating Dioxygen : A Computational study
Sammanfattning : Quantum chemistry has nowadays become a powerful and efficient tool that can be successfully used for studies of biosystems. It is therefore possibleto model the enzyme active-site and the reactions undergoing into it, as well as obtaining quite accurate energetic profiles. LÄS MER
