1. Flexibility – a tool for chirality control in asymmetric catalysis
Sammanfattning : This thesis deals with the design and synthesis of ligands for asymmetric catalysis: palladium catalyzed allylic alkylations, and rho-dium and iridium catalyzed hydrogenations of olefins. Chirally flexible phosphepine ligands based on biphenyl were synthesized and their properties were studied. LÄS MER
2. Investigation of Symmetry and Electronic Effects in Asymmetric Palladium-Catalysed Allylic Substitutions
Sammanfattning : .... LÄS MER
3. Investigations of New Biomimetic Transamination Systems and Inclusion Complexation with Cyclodextrins
Sammanfattning : Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. LÄS MER
4. Bispyridylamides as ligands in asymmetric catalysis
Sammanfattning : This thesis deals with the preparation and use of chiralbispyridylamides as ligands in metal-catalyzed asymmetricreactions. The compounds were prepared by amide formation usingdifferent coupling reagents. LÄS MER
