  4. 3. Oxidative Trifluoromethylation and other Functionalization Reactions of Alkenes and Alkynes

    Författare :Pär Janson; Kálmán Szabó; Antonio Togni; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; transition metal; trifluoromethylation; catalysis; acetoxylation; difunctionalization; oxidation; mechanistic study; alkenes; alkynes; quinones; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis concerns the use of various potent oxidants in organic synthesis. The main focus is directed at selectively introducing trifluoromethyl groups into compounds containing double or triple bonds. All reactions proceed under mild conditions and can in most cases be performed on the bench-top. LÄS MER
