2. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 Catalyst Immobilization in Ionic Liquid for H2O2 OxidationsDetta är en avhandling från Stockholm : Institutionen för organisk kemi
Sammanfattning : This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. LÄS MER

Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER

Sammanfattning : Four different catalytic systems were studied for biomimetic coupled oxidations using H2O2 or O2. In the first example, osmium tetroxide works as a substrate-selective catalyst for dihydroxylation of olefins. Electron transfer to H2O2 is facilitated by electron transfer mediators (ETMs). LÄS MER
- Detta är en avhandling från Angeliki Öste Triantafyllou, Dept. of Biotechnology, Lund University, Box 124, 221 00 Lund, Sweden
Sammanfattning : The use of enzymes in nonaqueous media has considerably expanded their potential areas of application. Limitations however arise that are inherent to the low conformational flexibility of enzymes in dry organic media. Enzyme activity is often unfavorably low due to kinetic barriers. LÄS MER
