    Sammanfattning : This thesis deals with the development of transition metal-catalyzed silaborations of 1,3-dienes and 1,6-enynes. The first part of the thesis describes the development of the enantioselective 1,4-silaboration of 1,3-cyclohexadiene. A number of chiral metal-ligand complexes were evaluated. LÄS MER

  3. 2. C-H Activation Reactions Mediated by Pd Based Heterogeneous Catalysts : Regioselective Formation of C-O and C-X Bonds

    Författare :Maitham Majeed; Centrum för analys och syntes; []
    Nyckelord :C-H Activation; N-heterocyclic carbenes; palladium; polymer supported Pd II ; undirected acetoxylation; directed halogenation; continuous flow; reduced graphene oxide supported Pd II ;

    Sammanfattning : New classes of N-heterocyclic carbene-palladium(II) complexes containing either a vinyl group in different positions or an anthracene tag in the backbone of the N-heterocycle were synthesized and fully characterized. The vinyl based complexes were copolymerized with divinylbenzene to fabricate robust polymer-supported NHC-Pd(II) systems, while the anthracene based complexes were π-stacked onto the surface of reduced graphene oxide (rGO) producing immobilized catalysts with interesting features.

  4. 3. PEPPSI-type Complexes of Palladium and Platinum: : Investigation of Properties and Applications in Catalysis

    Författare :Ekaterina Bolbat; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEPPSY-type complexes; palladium; platinum; C−H activation; supported homogeneous catalysts;

    Sammanfattning : Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. LÄS MER

  5. 4. Surface-Induced Modification of Supported Late Transition Metal Complexes

    Författare :Olesia Snezhkova; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

    Sammanfattning : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. LÄS MER
