  2. 11. Mechanistic investigation of platinum and palladium catalysed cross- coupling reactions. Implications for the Stille and Heck reactions

    Author : Patrik Nilsson; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Oorganisk kemi; Inorganic chemistry; parameter fitting; numerical solutions; platinum II ; palladium II ; NMR spectroscopy; transmetallation; Heck; Stille; kinetics; mechanism;

    Abstract : The present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. READ MORE

  4. 12. Studies on Palladium-Catalyzed Carbocyclizations of Allene-Substituted Olefins and 1,3-Dienes

    Author : Katja Närhi; Jan-Erling Bäckvall; Giovanni Poli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organometallic Chemistry; Homogenous Catalysis; Palladium; Allenes; C-C bond formation; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the development and mechanistic studies of carbocyclization reactions of allene-substituted olefins and 1,3-dienes, catalyzed by palladium(0) and palladium(II). These reactions results in the formation of [n,3,0] bicyclic systems (n = 3-5) with high stereoselectivity and in good to excellent yields. READ MORE

  6. 14. Organometallic complexes with antimalarial properties

    Author : Lotta Glans; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganometallic chemistry; Chloroquine; Antimalarial; Drug resistance; Organometallic; Arene;

    Abstract : Malaria is a serious disease that causes around 800 000 deaths per year. Current malaria control efforts are hampered by the widespread resistance to common antimalarial drugs, such as the 4-aminoquinoline derivative called chloroquine. READ MORE

  7. 15. Cluster-Based Catalysts for Asymmetric Synthesis

    Author : Viktor Moberg; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Oorganisk kemi; Inorganic chemistry; Kemi; Chemistry; hydride; cobalt; osmium; ruthenium; cyclocarbonylation; Pauson-Khand; carbonyl cluster; asymmetric hydrogenation;

    Abstract : In this work, the synthesis and characterisation of new low-valence transition metal carbonyl clusters, and an investigation into their viability to act as catalysts/catalyst precursors in asymmetric synthesis, are described. Carbonyl clusters based on ruthenium and osmium have been tested as (pre)catalysts for asymmetric hydrogenation of alpha-unsaturated carboxylic acids, and cobalt carbonyl clusters have been used as (pre)catalysts in (asymmetric) Pauson-Khand synthesis.
