  2. 1. Chemo-Enzymatic Epoxidation of Unsaturated Fatty Acids

    Author : Cecilia Orellana Coca Åkerman; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; solvent-free process.; Candida antarctica lipase B esterification; chemo-enzymatic epoxidation; Unsaturated fatty acids; epoxides;

    Abstract : Epoxy fatty acids are useful molecules and find a number of applications e.g. as PVC plasticisers and stabilisers, additives in polyurethane production, reactive diluents in paints, corrosion protection agents, etc. READ MORE

  4. 2. High Valent Metal Oxo Complexes as Oxidation Catalysts

    Author : Kamal Hossain; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molybdenum; tungsten; Vanadium; oxygen atom transfer; epoxidation; sulfoxidation; molybdenum; tungsten; vanadium; oxygen atom transfer; epoxidation; sulfoxidation;

    Abstract : A series of new dioxomolybdenum(VI) and -tungsten(VI) complexes of tripodal tetradentate and tridentate amino bis- and monophenolate ligands have been synthesized and characterized. The majority of the complexes are mononuclear, but dimeric and trimeric oxo-bridged M(VI) (M = Mo, W) were also obtained. READ MORE

  5. 3. Biomimetic Reactions : Water Oxidation and Aerobic Oxidation

    Author : Lien-Hoa Tran; Björn Åkermark; Nina Kann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis deals mainly with two oxidation reactions: water oxidation and aerobic oxidation, both of which have been applied in a biomimetic fashion. In the former reaction molecular oxygen is generated whereas in the latter it was used as terminal oxidant in oxidation reactions. READ MORE

  6. 4. Symmetry in Asymmetric Catalysis and Hydrogen Bond-Based Self-Assembly : Synthesis and Investigations

    Author : Yutang Li; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; bissalen; asymmetric ring opening; pseudo-Cs; hydrogen bonding; self-assembly; C3 symmety; trilactam; scXRD; solubility; epoxidation; rearrangement; Baeyer-Villiger reaction; transition state; DFT calculation; cyclodextrin; polyethylene glycol; amphiphilicity;

    Abstract : The thesis elaborates on four different projects focusing on synthesizing symmetry-related molecules and investigating their performance as catalysts for asymmetric catalysis or as monomers for hydrogen bond-based self-assembly.Chapter 2 describes a new method to desymmetrize a meso-ligand.
