  3. 3. Structural and Spectroscopic Studies of Solvated Metal Ions

    Författare :Alireza Abbasi; Magnus Sandström; Ernö Brucher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination; Solvation; X-ray diffraction; EXAFS; IR; Raman; Normal coordinate analysis; trivalent metal ions; dmso; triflate; hydration; Chemistry; Kemi;

    Sammanfattning : Crystallographic and spectroscopic studies have been performed of structures, coordination and chemical bonding for series of trivalent metal ions solvated by two oxygen-coordinating solvents, water and dimethyl sulfoxide (DMSO). The hydrated scandium(III) and lanthanoid(III) ions, La to Lu, are surrounded by tricapped trigonal prisms of aqua ligands in the isomorphous series of trifluoromethanesulfonates, [M(H2O)n](CF3SO3)3.

  4. 4. Asymmetric Hydrogenations : Syntheses of Ligands and Expansion of Substrate Scope

    Författare :Pradeep Cheruku; Pher Andesson; Jay Siegel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Asymmetric; Hydrogenations; Reductions; Olefins; Imines; Enol phosphinates; Transition metal; Complexes; Iridium; Enamines; Ruthenium; Ligands; Trifluoromethyl; Diphenylvinylphosphine oxides; Vinyl phosphonates; Chemistry; Kemi;

    Sammanfattning : Asymmetric hydrogenation has emerged as a versatile methodology to obtain a wide range of chiral precursors. This thesis focused on the synthesis of new chiral ligands and the expansion of the substrate scope of asymmetric hydrogenations. LÄS MER

  5. 5. Photocatalysis beyond conventional precious metal complexes

    Författare :Rickard Lindroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Sammanfattning : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. LÄS MER
