1. Efficient and High-Yielding Routes to Diaryliodonium Salts
Abstract : 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. READ MORE

2. 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

3. Development of HIV-1 Protease Inhibitors and Palladium-Catalyzed Synthesis of Aryl Ketones and N-Allylbenzamides
Abstract : The use of palladium-catalyzed reactions to introduce new carbon-carbon bonds is a fundamental synthetic strategy that has been widely embraced due to its high chemo- and regioselectivity and functional group tolerance. In this context, Pd(0)-catalyzed aminocarbonylations using Mo(CO)6 instead of toxic and gaseous CO and with allylamine as the nucleophile were investigated. READ MORE

4. [11C]Carbon Monoxide in Palladium- / Selenium-Promoted Carbonylation Reactions : Synthesis of 11C-Imides, Hydrazides, Amides, Carboxylic Acids, Carboxylic Esters, Carbothioates, Ketones and Carbamoyl Compounds
Abstract : [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.

5. Development of Palladium-Promoted 11C/12C-Carbonylations and Radiosynthesis of Amyloid PET Ligands
Abstract : In the first part of this thesis, palladium(0)-catalyzed and -mediated carbonylations are discussed. Paper I describes a new method for the safe, efficient use of a solid carbon monoxide source in the synthesis of primary and secondary benzamides. READ MORE
