    Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER

  2. 2. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

    Författare :Daniel Olsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organometallic chemistry; Metallorganisk kemi; Organic chemistry; Oorganisk kemi; Inorganic chemistry; Suzuki reaction; Stille reaction; catalysis; cyclometalation; C-H activation; PCP complex; POCOP ligand; PCP ligand; iridium; palladium; platinum;

    Sammanfattning : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. LÄS MER

  3. 3. Metals in Dynamic Chemistry: Selection & Catalysis

    Författare :Brian J.J. Timmer; Olof Ramström; Stéphane Bellemin-Laponnaz; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; constitutional dynamic chemistry; selection; multivalent interactions; carbohydrates; quartz crystal microbalance; catalyst screening; aqueous olefin metathesis; C-H activation; Kemi; Chemistry;

    Sammanfattning : In the adaptation to the oxidative environment on earth, metals played a crucial role for the evolution of life. The presence of metals also allowed access to advanced functions due to their unique coordination sphere and reactivity. LÄS MER

  4. 4. Theoretical Reflections of Solvation in Polar Media

    Författare :Daniel Hagberg; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kvantkemi; Teoretisk kemi; quantum chemistry; Theoretical chemistry; Coordination; Water; Uranyl; Intermolecular forces; Simulation; Dielectric; Cluster; Hofmeister series; Ion; Interaction; Dipole;

    Sammanfattning : Using experiments it is rather easy to measure things on the macroscopic length scale, while it is much harder to measure something in the microscopic world like molecular structure. The opposite is true in theoretical chemistry. LÄS MER
