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

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

    Abstract : 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. READ MORE

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

    Author : Eduardo Maurina Morais; Chalmers University of Technology; []
    Keywords : Protic ionic liquids; Fuel cells; Synthesis; DFT;

    Abstract : 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. READ MORE

  3. 3. Synthesis and characterisation of heterobimetallic erbium alkoxides

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

    Abstract : 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. READ MORE

  4. 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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE
