   Sammanfattning : In this thesis, in situ ambient pressure X-ray photoelectron spectroscopy has been used to address chemical reactions on surfaces. The presented work aims at the investigation of the relation between pressure and adsorbate surface structures during catalytic reactions. LÄS MER

3. 2. 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
