  1. 1. Supported Mono- and Bimetallic Gold Nanoparticle Catalysts for Different Organic Transformations

    Författare :Sheetal Sisodiya; Centrum för analys och syntes; []
    Nyckelord :Gold nanoparticles; coupling reaction; styrene epoxidation; bimetallic nanoparticle; supported gold nanoparticle;

    Sammanfattning : Supported gold nanoparticles are emerging as an important class of catalysts for various organic transformations due to their tunable properties. This thesis embraces the fundamental studies of supported gold nanoparticles for different organic reactions from the viewpoint of understanding the role of synthesis methods, nature of carriers, and addition of second metal on the properties and functions of gold catalysts.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molybdenum; tungsten; Vanadium; oxygen atom transfer; epoxidation; sulfoxidation; molybdenum; tungsten; vanadium; oxygen atom transfer; epoxidation; sulfoxidation;

    Sammanfattning : A series of new dioxomolybdenum(VI) and -tungsten(VI) complexes of tripodal tetradentate and tridentate amino bis- and monophenolate ligands have been synthesized and characterized. The majority of the complexes are mononuclear, but dimeric and trimeric oxo-bridged M(VI) (M = Mo, W) were also obtained. LÄS MER

  4. 3. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands
