  1. 1. Metallacyclic Phosphine Complexes and Intramolecular Csp3-H Bond Activation -Synthesis, Characterisation and Catalytic Application

    University dissertation from Sven Sjövall, Inorganic Chemistry, Chemical Center, Lund University

    Author : Sven Sjövall; Lund University.; Lunds universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; Heck; diphosphite; diphosphine; phosphine; cyclometallation; C-C activation; C-O activation; C-H activation; palladium; rhodium; iridium; Inorganic chemistry; Oorganisk kemi;

    Abstract : The work presented in this thesis deals with metallacyclic late transition metal complexes, obtained by intramolecular Csp3-H activation, and the application of such compounds in catalysis. The new hemilabile P,O phosphines N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (DPPAM), o-(diphenylphosphino)benzoic acid ethyl ester (DPPES), o-(diphenylphosphino)benzoic acid methyl ether (DPPET) and ±-1-(2- diphenylphosphino)phenylethyl propionate (±-DPPMES) and the symmetrical diphosphorus donor ligands cis-1,3-bis[(diphenylphosphino)methyl]-cyclohexane (DPCY), cis-1,3-bis[(di-tertbutylphosphino)methyl]cyclohexane (DTBCY) and cis-1,3-bis[(di-isopropylphosphino)methyl]cyclohexane (DIPCY) have been synthesised, allowing the preparation of a range of new metallacyclic rhodium(III), iridium(III) and palladium(II) complexes.

  2. 2. Hyperpolarized Nuclei for NMR Imaging and Spectroscopy – Methodology and model studies of lung and vascular function

    University dissertation from Sven Månsson, Dept. of Experimental Research, Malmö University Hospital, SE–205 02 Malmö, Sweden

    Author : Sven Månsson; Lund University.; Lunds universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lung function; 3He; 13C; 129Xe; Elektroteknik; Electrical engineering; Magnetic resonance; hyperpolarized;

    Abstract : Based on the principle of nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) are widely used methods in medical diagnostic imaging and biological research. Clinical MRI has been restricted to imaging of protons, for reasons of sensitivity. READ MORE

  3. 3. The fuzzy front end of product innovation processes the influence of uncertainty, equivocality, and dissonance in social processes of evolving product concepts

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sven Andersson; Luleå tekniska universitet.; [2010]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovations; Fuzzy front end; Business Economics - Business studies; Innovationer; Ekonomi - Företagsekonomi; Accounting and Control; Redovisning och styrning;

    Abstract : Developing new products is essential for the long-term survival of companies. The fuzzy front end (FFE) is the first phase in the product innovation process and is considered an important determinant for successful product innovation. This thesis addresses the social process in which individuals evolve a product concept in the fuzzy front end. READ MORE
