  2. 21. Catalytic Processes Mediated by Metal−Organic Frameworks : Reactivity and Mechanistic Studies

    Author : Vlad Pascanu; Belén Martín-Matute; Seth Cohen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Abstract : The present thesis describes the development of heterogeneous catalytic methodologies using metal−organic frameworks (MOFs) as porous matrices for supporting transition metal catalysts. A wide spectrum of chemical reactions is covered. READ MORE

  4. 22. Development and Applications of Molybdenum-Catalyzed Chemoselective Amide Reduction

    Author : Tove Slagbrand; Hans Adolfsson; André Charette; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrosilylation; reduction; reductive functionalization; catalysis; amides; enamines; chemoselective; organisk kemi; Organic Chemistry;

    Abstract : This thesis covers the development of catalytic methodologies for the mild and chemoselective hydrosilylation of amides. The first part describes the investigation of the Mo(CO)6-catalyzed reduction of carboxamides. READ MORE

  5. 23. Structure and function of relaxins

    Author : Linda M. Haugaard-Kedström; Johan Rosengren; Torleif Härd; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relaxin; insulin-like peptide; peptide hormone; peptide synthesis and NMR; Organic Chemistry; Organisk kemi;

    Abstract : The relaxin/insulin superfamily is a group of peptide hormones that consists of ten members in human, namely relaxins 1-3, insulin-like peptides (INSL) 3-6, insulin and insulin-like growth factors (IGF) I-II. These peptides have various functions in the body, such as regulating growth, blood glucose levels,  collagen metabolism, germ cell maturation and appetite. READ MORE

  6. 24. Metal Organic Frameworks: History, Synthesis, and Topological approach

    Author : Cédric Borel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MOF; crystal structures; crystal engineering; network; coordination chemistry; synthesis; TOPOS; systre; gas storage;

    Abstract : The storage, separation, purification and catalytic reactions of small molecules are important research domains in both pure and applied chemistry, where porous materials play a major role. Among the different possible options for the preparation porous materials a recent approach is to build structures based on metal ions, metal complexes, or metal clusters, bridged by organic ligands.

  7. 25. Chiral Separation of Amines by Non-Aqueous Capillary Electrophoresis using Low Molecular Weight Selectors

    Author : Ylva Hedeland; Curt Pettersson; Ulf Bondesson; Lars Blomberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pharmaceutical chemistry; Chiral Separation; Non-Aqueous Capillary Electrophoresis; Enantioresolution; Electro-osmotic Flow; Pharmaceuticals; Enantiomeric Amines; Low Molecular Weight Selector; Farmaceutisk kemi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : Three chiral selectors (diketogulonic acid, benzoxycarbonylglycylproline and ketopinic acid) have been introduced for enantioseparation of pharmacologically active amines in non-aqueous capillary electrophoresis. The use of organic solvents, instead of aqueous buffers in the background electrolyte facilitated ion-pair formation between the analytes and the chiral selectors. READ MORE
