    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; open-framework; zeolites; germanates; nickel germanates; structure directing agent; nickel complexes; crystal structure determination; hydrothermal synthesis; strukturkemi; Structural Chemistry;

    Abstract : Microporous materials have a wide range of important applications in separation, gas adsorption, ion-exchange and catalysis. Open-framework germanates are a family of microporous compounds and are of particular interest. READ MORE

  2. 2. Homogeneous and heterogeneous Cp*Ir(III) catalytic systems : Mechanistic studies of redox processes catalyzed by bifunctional iridium complexes, and synthesis of iridium-functionalized MOFs

    Author : Greco González Miera; Belén Martín-Matute; Matt Clarke; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; catalysis; bifunctional; metal-ligand cooperation; amine alkylation; Hammett; kinetics; acceptorless alcohol dehydrogenation; MOF; transition metal; synchrotron; Organic Chemistry; organisk kemi;

    Abstract : The purpose of this doctoral thesis is to investigate and develop catalytic processes mediated by iridium(III) complexes. By understanding the mechanisms, the weaknesses of the designed catalysts can be identified and be overcome in the following generation. READ MORE

  4. 4. Unsymmetric PCN Pincer Palladium and Nickel Complexes : Synthesis, Characterization and Reactivity

    Author : Abdelrazek Mousa; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Unsymmetric PCN; Palladium; Nickel; Cyclometallation; Carboxylation; Cross-coupling;

    Abstract : New palladium and nickel complexes based on unsymmetric PCN pincer ligands have been synthesized and fully characterized using different techniques. The substituents on the nitrogen side arm of the ligand have great influence on the cyclometallation and the reactivity of the new complexes particularly in case of nickel. READ MORE

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

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

    Abstract : 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.
