1. Catalytic Amide Reductions under Hydrosilylation Conditions
Sammanfattning : This thesis covers the development of catalytic methodologies for the mild and chemoselective reductions of amides. The first part of the thesis describes the use of a Fe(II)/NHC catalyst for the deoxygenation of aromatic tertiary amides to corresponding amines. LÄS MER
2. Catalytic Hydrosilylation of Amides
Sammanfattning : In this thesis, different protocols and approaches are described for thehydrosilylation of tertiary amides to amines or enamines. The development of simple andeffective methods for the production of amines from amides is of great importance to bothacademic and industrial users, since the final product represents a valuable building blockfor fine and bulk chemicals.

3. Development and Applications of Molybdenum-Catalyzed Chemoselective Amide Reduction
Sammanfattning : This thesis covers the development of catalytic methodologies for the mild and chemoselective hydrosilylation of amides. The first part describes the investigation of the Mo(CO)6-catalyzed reduction of carboxamides. LÄS MER
4. Transition metal-catalyzed reduction of carbonyl compounds : Fe, Ru and Rh complexes as powerful hydride mediators
Sammanfattning : A detailed mechanistic investigation of the previously reported ruthenium pseudo-dipeptide-catalyzed asymmetric transfer hydrogenation (ATH) of aromatic ketones was performed. It was found that the addition of alkali metals has a large influence on both the reaction rate and the selectivity, and that the rate of the reaction was substantially increased when THF was used as a co-solvent.

5. Impact of Secondary Interactions in Asymmetric Catalysis
Sammanfattning : 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. LÄS MER
