1. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity
Abstract : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. READ MORE

2. Iridium-Catalyzed C−H Activation Methods for Late-Stage Functionalization of Pharmaceuticals
Abstract : C-H activations have over the recent decades risen from a mere curiosity to a viable synthetic strategy. However, challenges in terms of accessible transformations, selectivity and functional group tolerance limit the widespread applicability of this approach. READ MORE

3. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism
Abstract : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. READ MORE

4. Asymmetric Hydrogenations of Imines, Vinyl Fluorides, Enol Phosphinates and Other Alkenes Using N,P-Ligated Iridium Complexes
Abstract : The research described in this thesis is directed toward the efficient, enantioselective synthesis of chiral products that have useful functionality. This goal was pursued through catalytic asymmetric hydrogenation, a reaction class that selectively introduces one or two stereocenters into a molecule in an atom-efficient step. READ MORE

5. Impact of Secondary Interactions in Asymmetric Catalysis
Abstract : This thesis deals with secondary interactions in asymmetric catalysis and their impact on the outcome of catalytic reactions. The first part revolves around the metal-catalyzed asymmetric allylic alkylation reaction and how interactions within the catalyst affect the stereochemistry. READ MORE
