  4. 4. Development of Biomimetic Catalytic Systems for Selective Oxidations with H2O2 and O2

    University dissertation from Department of Organic Chemistry

    Author : Mikael Johansson; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomimetic oxidations; catalyst immobilization; dihydroxylation; sulfoxidation; flavin; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Organic Chemistry; organisk kemi;

    Abstract : 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).

  5. 5. Studies of Biomimtic Oxidations and Racemizations

    University dissertation from Stockholm : Institutionen för organisk kemi

    Author : Gábor Csjernyik; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxidation of alcohols; ruthenium; porphyrin; racemization;

    Abstract : This thesis deals with studies of ruthenium-catalyzed hydrogen transfer reactions for oxidations and racemization.Through optimisation of the substrate-selective redox catalyst, the electron and proton transfer mediator (a benzoquinone derivative), and the oxygen-activating metal macrocycle a highly efficient biomimetic oxidation of secondary alcohols was obtained.
