  1. 1. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

    Detta är en avhandling från Department of Biotechnology, Lund University

    Författare :Benoit Guieysse; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

    Sammanfattning : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. LÄS MER

  2. 2. Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Fredrik Ek; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bengamide analogue.; parallel synthesis; trimethylsilyl azide; cycloaddition; imidazole; fused tetrazole derivatives; iodocyclization; benzazepine; tert-butyl nitrite; allylic bromide; aromatic allylation; diazotization; Organic chemistry; Organisk kemi;

    Sammanfattning : A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. LÄS MER

  3. 3. Ionization and Fragmentation of Complex Molecules and Clusters Biomolecules and Polycyclic Aromatic Hydrocarbons

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

  5. 5. Asymmetric Transfer Hydrogenation of Aromatic Ketones : Catalyst Development and Mechanistic Studies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sofia Nordin; Torbjörn Frejd; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; transfer hydrogenation; aza-norbornyl structure; amino acid derivatives; amino alcohols; ruthenium; concerted mechanism; asymmetric catalysis.; Organisk kemi; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis describes the development and evaluation of new chiral Ru(arene)(amino alcohol) catalysts for the transfer hydrogenation of aromatic ketones using isopropanol as the hydrogen source. Two mechanistic studies of the Ru(arene)(amino alcohol) catalyzed transfer hydrogenation of acetophenone were also conducted. The Ru(arene)[(1S,3R,4R)-3. LÄS MER
