  1. 1. Unveiling Catalytic Species in Suspension/Solution-Based Reactions by In Situ X-Ray Absorption Spectroscopy : Evolution of Palladium and Ruthenium Species

    Författare :Ning Yuan; Xiaodong Zou; Ingmar Persson; Gopinathan Sankar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium and ruthenium species; Catalysts; Suspension and solution; In situ X-ray absorption spectroscopy; Activation; Deactivation; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : The palladium (Pd) and ruthenium (Ru) species in several attractive catalysts have been probed using X-ray absorption spectroscopy (XAS). The study of catalyst evolution in suspension- and solution-based reactions was the primary aim. It was achieved by performing in situ XAS experiments on Pd and Ru over the course of the reactions.

  3. 2. Transition Metal-Catalyzed Redox Reactions : A Journey from Homogeneous Ruthenium to Heterogeneous Palladium Catalysis

    Författare :Oscar Verho; Jan-Erling Bäckvall; Manfred Reetz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Sammanfattning : The first part of the thesis covers the development and utilization of electronically modified (pentaarylcyclopentadienyl)Ru-complexes in the racemization of secondary alcohols. This study revealed that the electronic properties of the substrate were the main factors dictating whether β-hydride elimination or hydride re-addition becomes the rate-determining step of the racemization process.
