  4. 3. Activation of CO2 by Palladium Complexes Bearing Tridentate PCP Ligands

    Författare :Roger Johansson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Kinetics; Insertion reactions; PCP ligands; CO2 activation; Palladium II complexes;

    Sammanfattning : The present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. LÄS MER
