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

2. The chemistry of organic iodides under severe nuclear accident conditions in LWRs
Abstract : For many countries nuclear fission is an important part of their energy portfolio. However, a great concern is the occurrence of nuclear reactor accidents, which can result in the emission of radioactivity into the environment. READ MORE

3. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions
Abstract : During severe nuclear reactor accidents such as Chernobyl or Fukushima large amounts of radioactive iodine can be released in form of inorganic and organic iodine species into the environment. Volatile radioactive iodine species are harmful to human health when inhaled. READ MORE

4. Exploring Palladium-Mediated 11C/12C-Carbonylation Reactions : PET Tracer Development Targeting the Vesicular Acetylcholine Transporter
Abstract : The work presented herein describes the utilization and exploration of palladium-mediated incorporations of carbon monoxide and/or [11C]carbon monoxide into compounds and structural motifs with biological relevance.The first part of the thesis describes the design, synthesis and 11C-labeling of prospective PET tracers for the vesicular acetylcholine transporter (VAChT), a target affected in several neurodegenerative diseases.

5. Photoinitiated Radical Carbonylation Using [11C]Carbon Monoxide : 11C-Labelling of Aliphatic Carboxylic Acids, Esters, and Amides
Abstract : One-step photoinitiated free radical carbonylation was employed for the rapid (5–7 min) labelling of aliphatic carboxylic acids, esters, and amides with a short-lived positron emitter 11C (t½ = 20.3 min) at the carbonyl position. The labelled compounds were synthesized from alkyl iodides (0.05–0. READ MORE
