  1. 1. Stabilitly analysis of large structures founded on rock : an introductory study

    Författare :Fredrik Johansson; Håkan Stille; Anders Fredriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : Previous investigations of Swedish and international dams have shown difficultiesto assess the safety against failure in rock foundations. The problem was alsogiven additional interest in connection to the recent construction of the newbridge at Traneberg in Stockholm. LÄS MER

  3. 2. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

    Författare :Daniel Olsson; Centrum för analys och syntes; []

    Sammanfattning : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. LÄS MER

  4. 3. Mechanistic investigation of platinum and palladium catalysed cross- coupling reactions. Implications for the Stille and Heck reactions

    Författare :Patrik Nilsson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Oorganisk kemi; Inorganic chemistry; parameter fitting; numerical solutions; platinum II ; palladium II ; NMR spectroscopy; transmetallation; Heck; Stille; kinetics; mechanism;

    Sammanfattning : The present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. LÄS MER

  5. 4. Methods for the Synthesis of PET Tracers and NMR Studies of Ribonuclease A

    Sammanfattning : This thesis contains two parts.In the first part, general and versatile palladium-mediated 11C-C bond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. LÄS MER

  7. 5. Novel Metal-Mediated Organic Transformations : Focusing on Microwave Acceleration and the Oxidative Heck Reaction

    Författare :Per-Anders Enquist; Mats Larhed; Anders Hallberg; Troels Skrydstrup; Uppsala universitet; []
    Nyckelord :Organic chemistry; palladium II ; oxidative Heck reaction; high-throughput-chemistry; microwave acceleration; dicobalt octacarbonyl; in situ carbonylation; urea; diaryl ketones; ESI-MS; Organisk kemi;

    Sammanfattning : Transition metals have played an important role in synthetic organic chemistry for more than a century, and offer catalytic transformations that would have been impossible with classical chemistry. One of the most useful and versatile of the transition metals is palladium, which over the years has catalyzed many important carbon-carbon forming reactions. LÄS MER
