  1. 6. Palladium-Catalyzed Synthesis and Transformation of Organoboranes

    Författare :Sara Sebelius; Kálmán J. Szabó; Todd Marder; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allylborane palladium; Organic chemistry; Organisk kemi; SRA - Molecular Bioscience;

    Sammanfattning : This thesis presents the development of new palladium-catalyzed transformations involving synthesis and application of allylborane reagents. In these reactions various palladium sources, including pincer complexes and commonly used catalysts were applied. LÄS MER

  3. 7. Palladium-catalyzed aromatic coupling and allylic substitution

    Författare :Helena Hagelin; KTH; []
    Nyckelord :;

    Sammanfattning : Different types of palladium(II)-catalyzed aromatic couplingreactions have been investigated.The cyclization of diphenyl ether was found to be moresensitive to reaction conditions than was the cyclization ofthe diphenylamine derivatives. LÄS MER

  4. 8. Synthesis of C(sp2)-P bonds by palladium-catalyzed reactions : Mechanistic investigations and synthetic studies

    Författare :Marcin Kalek; Jacek Stawinski; Jean-Luc Montchamp; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis focuses on synthetic and mechanistic aspects of palladium-catalyzed C(sp2)-P bond-forming reactions, with the aim to develop mild and efficient methods for the synthesis of biologically active phosphorus compounds, e.g. DNA analogs. LÄS MER

  5. 9. 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.

  7. 10. Palladium-Catalyzed Synthesis and Transformations of Organometallic Compounds

    Författare :Olov Wallner; Kálmán Szabó; Robin Bedford; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis is focused on two important fields of palladium catalysis: the development of electrophilic allylic substitution reactions via bis-allylpalladium intermediates; and application of palladium pincer-complexes in the synthesis and transformations of organometallic compounds.Palladium-catalyzed electrophilic allylation of aldehyde and imine substrates could be achieved using readily available allyl chlorides and acetates by employing hexamethylditin or bis(pinacolato)diboron reagents.
