  4. 3. Catalytic Methods to Convert Allylic Substrates through Hydride and Proton Shifts : Transition Metal-Catalyzed and Organocatalyzed Approaches

    Författare :Samuel Martinez-Erro; Belén Martín-Matute; Franziska Schoenebeck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allylic substrates; Iridium catalysis; Base catalysis; Method development; Isomerization; Hydride shift; Proton shift; Mechanistic studies; organisk kemi; Organic Chemistry;

    Sammanfattning : The present thesis describes the development of new catalytic protocols to transform allylic substrates into a wide variety of versatile carbonyl and vinyl organic compounds. All procedures that are described in this work have in common the existence of one or more hydrogen shifts as key steps in the mechanism of the reactions. LÄS MER

  5. 4. Transition Metal Hydride Complexes and Hydrogenated Gallium Clusters : Synthesis and Structural Properties

    Författare :Henrik Fahlquist; Dag Noréus; Maximilian Fichtner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal hydrides; Solid state Synthesis; X-ray diffraction; Neutron Scattering; strukturkemi; Structural Chemistry;

    Sammanfattning : Synthesis and structural characterisation of metal hydrides in two important systems are presented. The first system presented is low valent cobalt and nickel complex hydrides with the compositions BaMg5Co2H10, RbMg5CoNiH10, SrMg2CoH7and Sr4Mg4Co3H19 featuring nickel with oxidation state of 0 and cobalt with oxidation state +I and -I.
