Organic reactions catalyzed by copper(I) hydride complexes
… reaction. Finally, a mechanistic model for the regiodivergence is proposed on the basis of density functional theory calculations. Chapter 3. Enantioselective Ketone Allylation Using Allene, a Petroleum Cracking Byproduct Allene gas is produced and separated on million-metric-ton scale per year …

Zirconium-mediated alkyene-aldehyde coupling, rhodium-catalyzed alkene hydrothiolation, and copper-catalyzed alkyne hydroarylation: Reaction development and mechanistic investigations
… afford either 1,2- or 1,3-aminothioethers. The regiodivergence is a result of the ligand employed. Ligands with small bite angles afford the 1,3-isomer, while ligands with large bite angles afford the 1,2-isomer. Mechanistic experiments suggest that both reactions proceed through an oxidative …

Development of new transition metal-catalyzed carbon-fluorine, carbon-nitrogen, and carbon-carbon bond forming processes
… Alkylation of Indoles with Ligand-Controlled Regiodivergence A method for the enantioselective synthesis of either NI- and C3-chiral indoles by CuH-catalysis, depending on the choice of ligand, was developed. In contrast to conventional indole functionalization in which indoles are used as …

Towards the Development, Application and Understanding of Copper-Catalysed Alkene Functionalisation Processes Using Iodonium Salts
This thesis comprises three projects focused on the use of the combination of catalytic copper and iodonium salts towards the functionalisation of alkenes. Chapter 2 details the development of an enantioselective and regiodivergent allylic amide arylation procedure using a specific …
