  2. 1. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application

    Author : Torsten Malmström; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enantioselective; SAP; hydrogenation; hydroformylation; catalysis; biphasic; rhodium; poly-ethylene imine; poly-acrylic acid; polymers; water-soluble; phosphines; Inorganic chemistry; Oorganisk kemi;

    Abstract : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH.

  4. 2. Self-adaptable catalysts : Importance of flexibility and applications in asymmetric catalysis

    Author : Ester Fjellander; Christina Moberg; Jay Siegel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptable; flexible; semi-flexible; symmetry; conformational study; mechanistic study; rotation barrier; VT NMR; asymmetric catalysis; ligand design; allylic alkylation; hydrogenation; azepines; dioxaphosphepines; phosphepines; amines; phosphines; phosphoramidites; phosphinites; palladium; rhodium; Organic chemistry; Organisk kemi;

    Abstract : The topic of this thesis is the design and synthesis of biaryl-based self adaptableligands for asymmetric metal catalysis. The results discussed in papers I-III are covered, together with some unpublished results concerning substrate-adaptable catalysts. A general survey of self-adaptable catalysts is presented first.

  7. 5. Adsorption of Organic Phosphines and Thiols on Metal Surfaces

    Author : Hans Kariis; Per Persson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis investigations of the adsorption of small molecules on metal surfaces are presented. Several surface sensitive analytical methods are used in the studies.Surface modification of gold is a field in which an enormous amount of work has been published in recent years. READ MORE
