    Sammanfattning : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.

  3. 2. Development of novel PET radioligands for visualizing beta cell mass and amyloid plaques

    Författare :Mahabuba Jahan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of the thesis was twofold. The first aim was to radiolabel small molecules by using carbon-11 and fluorine-18 for visualising beta cell mass (BCM) in the pancreas by PET. Diabetes Mellitus (DM) is a chronic metabolic disorder that results from an absolute or relative lack of BCM of endocrine pancreas. LÄS MER
