2. 1. Catalytic Amide Reductions under Hydrosilylation Conditions

   Author : Alexey Volkov; Hans Adolfsson; Andrei K. Yudin; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrosilylation; amides; reduction; chemoselectivity; organisk kemi; Organic Chemistry;

   Abstract : 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. READ MORE

4. 2. Catalytic Hydrosilylation of Amides

   Author : Alexey Volkov; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : 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.

   Author : Tove Slagbrand; Hans Adolfsson; André Charette; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrosilylation; reduction; reductive functionalization; catalysis; amides; enamines; chemoselective; organisk kemi; Organic Chemistry;

   Abstract : 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. READ MORE

6. 4. Transition metal-catalyzed reduction of carbonyl compounds : Fe, Ru and Rh complexes as powerful hydride mediators

   Author : Elina Buitrago; Hans Adolfsson; Robert Morris; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asymmetric catalysis; amino acid; N-heterocyclic carbene; iron; ruthenium; rhodium; mechanistic investigation; kinetic study; asymmetric transfer hydrogenation; hydrosilylation; organisk kemi; Organic Chemistry;

   Abstract : 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.

7. 5. Impact of Secondary Interactions in Asymmetric Catalysis

   Author : Anders Frölander; Christina Moberg; Gerard van Koten; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; secondary interaction; hydrogen bond; chiral ligand; allylic alkylation; hydrosilylation; cyanation; pymox; box; PHOX; pybox; palladium; iridium; rhodium; Lewis acid; Lewis base; Organic chemistry; Organisk kemi;

   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
