   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

   Sammanfattning : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. LÄS MER

5. 4. C–H activation through late transition metal cyclometallation. Addressing selectivity and reactivity problems

   Författare :Mikhail Kondrashov; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C—H activation; cyclometallation; pincer ligands; anion exchange; bimetallic complexes; oxidative functionalisation;

   Sammanfattning : The ligand-directed C—H activation relies on a coordinating donor atom being in proximity to the C—H bond activated. Cyclometallation of 2-(1-naphthyl)-pyridine – a substrate containing both γ- and δ-positions in proximity to the directing nitrogen atom – was studied. LÄS MER

7. 5. New Strategies for Transition Metal-mediated (Hetero)arene Functionalization

   Författare :Fredric Ingner; Lukasz Pilarski; Joanna Wencel-Delord; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis describes new approaches to achieve efficient and selective (hetero)arene derivatization using transition metals. The main focus falls on the use of strategies based on C–H activation and organo-main group reactivity to render the synthesis of various (hetero)arene derivatives more direct, efficient, regioselective and sustainable.
