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

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

    Abstract : 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. READ MORE

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

    Author : Fredrik Ek; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE

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

    Author : Henrik A. B. Johansson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Thomas Schlathölter; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; fysik; Physics;

    Abstract : This work deals with ionization and fragmentation of biomolecules and polycyclic aromatic hydrocarbon (PAH) molecules. They are studied in the gas phase both as isolated molecules and as weakly bound clusters. READ MORE

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

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

    Abstract : 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. READ MORE
