  1. 1. Palladium-Catalyzed Carbocyclizations of Allenes with Unsaturated Hydrocarbons

    Författare :Johan Franzén; Jan-E. Bäckvall; Ross A. Widenhoefer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium-catalysis; Allenes; Organic chemistry; Organisk kemi;

    Sammanfattning : Palladium-catalyzed reactions of unsaturated hydrocarbons are important processes in organic chemistry especially for the generation of ring systems. This thesis describes the development and mechanistic studies of carbocyclization reactions of allenes with olefins, allyls or 1,3-dienes catalyzed by palladium(0)- and palladium(II)-complexes.

  3. 2. Palladium(II)-Catalyzed Oxidative Carbocyclization : Stereoselective Formation of C–C and C–B Bonds

    Författare :Tuo Jiang; Jan-Erling Bäckvall; Ross Widenhoefer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbocyclization; Palladium catalysis; Oxidation; Enallenes; Enynes; Borylation; Arylation; Asymmetric Catalysis; Chiral Brønsted acids; Chiral anion; organisk kemi; Organic Chemistry;

    Sammanfattning : Transition metal catalysis has emerged as one of the most versatile methods for the selective formation of carbon–carbon and carbon–heteroatom bonds. In particular, oxidative carbon–carbon bond forming reactions have been widely studied due to their atom economic feature. LÄS MER
