1. Iodonium Salts : Preparation, Chemoselectivity and Metal-Catalyzed Applications
Abstract : This thesis concerns the preparation and use of diaryliodonium salts. In Project I various unsymmetrical diaryliodonium salts were reacted with three different nucleophiles in order to study the chemoselectivity of the reactions of the salts. READ MORE

2. Diaryliodonium Salts : Synthesis, Applications and Computational Investigations
Abstract : Organic chemists have the ability to create complex organic molecules by connecting molecular building blocks in different ways. To name a few, these molecules are used as medicines, pesticides or in our household electronics, and are therefore crucial to life as we know it. READ MORE

3. Diaryliodonium Salts : Development of Synthetic Methodologies and α-Arylation of Enolates
Abstract : 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. READ MORE

4. Metal‐Free Arylations of Oxygen and Nitrogen Nucleophiles : Applications of Diaryliodonium Salts
Abstract : This thesis concerns development of new methods for metal‐free arylations in organic synthesis. The protocols discussed in the thesis are based on a class of hypervalent iodine compounds called diaryliodonium salts. These reagents are known to transfer aryl moieties to suitable nucleophiles.

5. Unsymmetrical Diaryliodonium Salts : Development and Chemoselectivity studies
Abstract : The first part describes a chemoselectivity study on diaryliodonium salts where oxygen, nitrogen and carbon nucleophiles have been arylated. Twelve different unsymmetric phenyl(aryl)iodonium salts were designed with a systematic variation of the steric and electronic properties of the aryl group. READ MORE
