  1. 11. Synthesis of 11C-labelled Alkyl Iodides : Using Non-thermal Plasma and Palladium-mediated Carbonylation Methods

    Författare :Jonas Eriksson; Bengt Långström; Philip H. Elsinga; Uppsala universitet; []
    Nyckelord :Organic chemistry; isotopic labelling; carbon-11; alkyl iodides; acrylamides; specific radioactivity; carbonylation; carbon monoxide; non-thermal plasma; PET; Organisk kemi;

    Sammanfattning : Compounds labelled with 11C (β+, t1/2 = 20.4 min) are used in positron emission tomography (PET), which is a quantitative non-invasive molecular imaging technique. It utilizes computerized reconstruction methods to produce time-resolved images of the radioactivity distribution in living subjects. LÄS MER
