6. Quantum Chemical Modelling of Enzymatic and Organometallic Reactions
Sammanfattning : In this thesis, density functional theory (DFT) is employed in the study of two enzymes and two organometallic systems.First, the natural reaction mechanism, as well as the enantioselective formation of α-hydroxyketones catalysed by two thiamine diphosphate (ThDP)- dependent enzymes, namely benzoylformate decarboxylase (BFDC) and 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylic-acid (SEPHCHC)- synthase (MenD), are investigated.

7. Synthesis of Nanoparticles and Organometallic Complexes for Gas Sensing
Sammanfattning : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. LÄS MER
8. BIOACTIVE ORGANOMETALLIC COMPOUNDS
Sammanfattning : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. LÄS MER

10. Aspects on the Regio and Stereo Selectivity in the Hydrolsilylation of 1,3-Dienes
Sammanfattning : This thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved.
