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

    University dissertation from Torsten Malmström. Inorganic chemistry 1, Chemical Center, Box 124, Lund University, 22100 Lund, Sweden

    Author : Torsten Malmström; Lund University.; Lunds universitet.; [1998]
    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.
