  1. 1. Exploring The Versatility Of Ionic Liquids : From fundamental understanding to materials inspired from ionic liquids

    Författare :Olivier Renier; Anja-Verena Mudring; Lydie Viau; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; liquid crystals; DSSC; molecular design; Luminescent materials; anhydrous compounds; phase transition; complex coordination; materialkemi; Materials Chemistry;

    Sammanfattning : Ionic liquids (ILs) have gained popularity as “green” and safe replacements for conventional organic solvents. They are defined as ionic salts displaying a melting point below 100 °C. Some of their unique characteristics also include negligible vapour pressure, good electrical conductivity as well as good thermal and chemical stability. LÄS MER

  3. 2. Synthesis of protic ionic liquids. Challenges and solutions for the synthesis of pure compounds

    Författare :Eduardo Maurina Morais; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protic ionic liquids; Fuel cells; Synthesis; DFT;

    Sammanfattning : The urgent need to diversify our energy matrix is responsible for a renewed interest in fuel cell technology, which can use hydrogen gas, a renewable green fuel, as an energy source. This technology is currently a commercially available option, however, it still requires technological improvements before it can be widely used for different applications. LÄS MER

  4. 3. Synthesis and characterisation of heterobimetallic erbium alkoxides

    Författare :Maria Wijk; Jean Galy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. LÄS MER

  5. 4. Catalytic Stereoselective Formation of C–O, C–C and C–B Bonds : A Voyage from Asymmetric Reactions Enabled by Lipases to Stereoselective Palladium-Catalyzed Oxidative Transformations of Enallenes

    Författare :Bin Yang; Jan Bäckvall; Matthias Beller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synthesis; Enzymatic kinetic resolution; Palladium; Allenes; Oxidative Transformations; Ruthenium; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis has been focused on enzymatic kinetic resolutions and stereoselective oxidative transformations of enallenes catalyzed by PdII.In the first part of the thesis, a detailed discussion on Candida antarctica lipase B (CALB)-catalyzed kinetic resolution (KR) of δ-functionalized alkan-2-acetates is shown.

  7. 5. Enzyme- and Transition Metal-Catalyzed Asymmetric Transformations : Application of Enzymatic (D)KR in Enantioselective Synthesis

    Författare :Richard Lihammar; Jan-Erling Bäckvall; Wolfgang Kroutil; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic Kinetic Resolution; Kinetic Resolution; Enzyme Catalysis; Asymmetric Synthesis; organisk kemi; Organic Chemistry;

    Sammanfattning : Dynamic kinetic resolution (DKR) is a powerful method for obtaining compounds with high optical purity. The process relies on the combination of a kinetic resolution with an in situ racemization. LÄS MER
