1. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil
Abstract : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. READ MORE

3. Transition Metal-Mediated Selective Functionalizations of Bio-Derived Building Blocks
Abstract : In order to transition to a more sustainable chemical industry, it is necessary to replace the fossil starting materials that are largely used today with renewable ones. Starting materials available from abundant natural sources, or which can be efficiently produced via a biotransformation, are of high interest in this regard. READ MORE

5. Development and Applications of Hypervalent Iodine Compounds : Powerful Arylation and Oxidation Reagents
Abstract : The first part of this thesis describes the efficient synthesis of several hypervalent iodine(III) compounds. Electron-rich diaryliodonium salts have been synthesized in a one-pot procedure, employing mCPBA as the oxidant. Both symmetric and unsymmetric diaryliodonium tosylates can be isolated in high yields. READ MORE
