1. 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

2. Mechanistic Studies on Ruthenium-Catalyzed Hydrogen Transfer Reactions
Abstract : Mechanistic studies on three different ruthenium-based catalysts have been performed. The catalysts have in common that they have been employed in hydrogen transfer reactions involving alcohols and ketones, amines and imines or both. READ MORE

3. Asymmetric Hydrogenations : Syntheses of Ligands and Expansion of Substrate Scope
Abstract : Asymmetric hydrogenation has emerged as a versatile methodology to obtain a wide range of chiral precursors. This thesis focused on the synthesis of new chiral ligands and the expansion of the substrate scope of asymmetric hydrogenations. READ MORE

4. Ruthenium-catalyzed hydrogen transfer involving amines and imines : Mechanistic studies and synthetic applications
Abstract : This thesis deals with ruthenium-catalyzed hydrogen transfer involving amines and imines and is divided into two parts. In Part 1 a mechanistic study has been performed. READ MORE
