  1. 11. Iridium Catalyzed Carbon- Heteroatom Bond Forming Reactions via Hydrogen Transfer : Method Development and Mechanistic Elucidations

    Författare :Aitor Bermejo López; Belén Martín‐Matute; Eduardo Peris; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; N-Heterocyclic carbene; N-Alkylation; Hydrogen transfer; Amino acids; Carbohydrates; Amines; Organic Chemistry; organisk kemi;

    Sammanfattning : The present thesis describes the applicability of two different iridium(III) complexes for C-O and C-N bond forming reactions. The different projects described in this work are united by the use of an iridium catalyst bearing a functionalized N-heterocyclic carbene ligand. LÄS MER

  3. 12. Modifying Cooking Practices to Reduce the Formation of Heterocyclic Amines

    Författare :Elna Hallgard; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; cancer; frying; mutagens; beefburger; chicken; heterocyclic amines; cooking;

    Sammanfattning : Commonly cooked meat dishes contain heterocyclic amines (HAs) at ng/g levels. HAs are animal carcinogens, form DNA adducts in human tissues, and have been associated with increased risk of cancer in epidemiological studies, and it is thus recommended that human intake be decreased.

  4. 13. Self-adaptable catalysts : Importance of flexibility and applications in asymmetric catalysis

    Författare :Ester Fjellander; Christina Moberg; Jay Siegel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptable; flexible; semi-flexible; symmetry; conformational study; mechanistic study; rotation barrier; VT NMR; asymmetric catalysis; ligand design; allylic alkylation; hydrogenation; azepines; dioxaphosphepines; phosphepines; amines; phosphines; phosphoramidites; phosphinites; palladium; rhodium; Organic chemistry; Organisk kemi;

    Sammanfattning : The topic of this thesis is the design and synthesis of biaryl-based self adaptableligands for asymmetric metal catalysis. The results discussed in papers I-III are covered, together with some unpublished results concerning substrate-adaptable catalysts. A general survey of self-adaptable catalysts is presented first.
