  7. 15. Investigation of Kinetically Labile Supramolecu-lar System Addressing Substrate Selectivity in the Catalytic Epoxidations of Olefins

    Författare :Fabrice Odille; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; enantioselectivity; Salen Mn III ; substrate selectivity; porphyrin; Jacobsen-Katsuki epoxidation; supramolecular catalysis; Hydrogen-bond; 2-pyridone;

    Sammanfattning : This thesis is devoted to the development and investigation of a supramolecular system used to catalyze Jacobsen-Katsuki epoxidations with the aim to attain substrate selectivity without product inhibition. The supramolecular catalyst is composed of two well-defined entities or units: a catalytic and a receptor. LÄS MER
