   Author : Ferran Planas; Fahmi Himo; Edina Rosta; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; enzyme; organometallic; mechanisms; organisk kemi; Organic Chemistry;

   Abstract : 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.

   Abstract : 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. READ MORE

5. 8. BIOACTIVE ORGANOMETALLIC COMPOUNDS

   Author : Haris Bjelosevic; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological; kinetic; gold; platinum; bioactive; phosphine; ruthenocene; Ferrocene;

   Abstract : 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. READ MORE

7. 10. Aspects on the Regio and Stereo Selectivity in the Hydrolsilylation of 1,3-Dienes

   Author : Magnus Gustafsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Organisk kemi; Organic chemistry; Lewis acid; electrophilic ring closure; asymmetric hydrosilylation; reaction conditions; isoprene; regioselectivity; oxygen; Wilkinsons catalyst; 15N-1H-HMQC; 31P; heterobidentate ligands; catalyst; palladium; epoxy-allylsilanes; rhodium complexes; dienes;

   Abstract : 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.
