  4. 3. Lanthanide Metal-Organic Frameworks and Hierarchical Porous Zeolitic Imidazolate Frameworks : Synthesis, Properties, and Applications

    Författare :Hani Nasser Abdelhamid; Xiaodong Zou; Belén Martín-Matute; Banglin Chen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal-organic frameworks; Zeolitic imidazolate frameworks; Lanthanide MOFs; Hierarchical porous ZIFs; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : This thesis presents the synthesis, properties, and applications of two important classes of metal-organic frameworks (MOFs); lanthanide MOFs and hierarchical porous zeolitic imidazolate frameworks (ZIFs). The materials have been characterized using a wide range of techniques including diffraction, imaging, various spectroscopic techniques, gas sorption, dynamical light scattering (DLS) and thermogravimetric analysis (TGA).

  5. 4. Transition metal-catalysed isomerisation of allylic alcohols : Applications to C−C, C−F and C−Cl bond formation

    Författare :Nanna Ahlsten; Belén Martín-Matute; M. J. Jonathan Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transiton metal-catalysis; allylic alcohols; isomerisation; halogenation; organisk kemi; Organic Chemistry;

    Sammanfattning : The focus of this thesis has been to develop selective and atom-economical methods for carbon-carbon and carbon-heteroatom bond formation, and to some extent improve on existing findings in this area. More specifically, methods for the catalytic generation of enolates from allylic alcohols and their in situ functionalisation with electrophilic reagents are described. LÄS MER
