1. Diaryliodonium Salts : Development of Synthetic Methodologies and α-Arylation of Enolates
Sammanfattning : This thesis describes novel reaction protocols for the synthesis of diaryliodonium salts and also provides an insight to the mechanism of α-arylation of carbonyl compounds with diaryliodonium salts. The first chapter gives a general introduction to the field of hypervalent iodine chemistry, mainly focusing on recent developments and applications of diaryliodonium salts. LÄS MER
2. Efficient and High-Yielding Routes to Diaryliodonium Salts
Sammanfattning : This thesis summarizes three novel and general reaction protocols for the synthesis of diaryliodonium salts. All protocols utilize mCPBA as oxidant and the acids used are either TfOH, to obtain triflate salts, or BF3•Et2O that gives the corresponding tetrafluoroborate salts in situ. LÄS MER
3. [11C]Carbon Monoxide in Palladium- / Selenium-Promoted Carbonylation Reactions : Synthesis of 11C-Imides, Hydrazides, Amides, Carboxylic Acids, Carboxylic Esters, Carbothioates, Ketones and Carbamoyl Compounds
Sammanfattning : [11C]Carbon monoxide in low concentrations has been used in palladium- or seleniummediated carbonylation reactions such as the synthesis of 11C-imides, hydrazides, amides, carboxylic acids, esters, carbothioates, ketones and carbamoyl compounds.In these reactions aryl iodides have been used in most cases.

4. The chemistry of organic iodides under severe nuclear accident conditions in LWRs
Sammanfattning : 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. LÄS MER
5. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions
Sammanfattning : 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. LÄS MER
