  4. 2. Biomimetic Reactions : Water Oxidation and Aerobic Oxidation

    Author : Lien-Hoa Tran; Björn Åkermark; Nina Kann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis deals mainly with two oxidation reactions: water oxidation and aerobic oxidation, both of which have been applied in a biomimetic fashion. In the former reaction molecular oxygen is generated whereas in the latter it was used as terminal oxidant in oxidation reactions. READ MORE

  5. 3. Modelling Chemical Reactions : Theoretical Investigations of Organic Rearrangement Reactions

    Author : Per-Erik Larsson; Sten Lunell; Nessima Salhi-Benachenhou; Olle Matsson; Osvaldo Goscinski; Ian H. Williams; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; Kvantkemi;

    Abstract : Chemical reactions are ubiquitous and very important for life and many other processes taking place on earth. In both theoretical and experimental studies of reactivity a transition state is often used to rationalise the outcome of such studies. READ MORE

  7. 5. Multicomponent Catalytic Reactions : Theoretical and Experimental Studies

    Author : Martin Pauze; Enrique Gomez Bengoa; Belen Martin-Matute; Vincent Gandon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-H Activation; Quaternary Quinolinium; Organocatalyst; Transition Metal Catalyst; Umpolung Strategy; Multi-step Reactions; Mechanistic Investigation; Density Functional Theory; organisk kemi; Organic Chemistry;

    Abstract : In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts is presented, and its mechanism also studied by DFT calculations. READ MORE
