2. 1. 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

4. 2. Organocatalytic Domino Reactions

   Author : Henrik Sundén; Armando Córdova; Pavel Kočovský; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; organocatalytic; domino; iminium-enamine; enamine-iminium; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Abstract : Organocatalyzed reactions involving activation strategies of ketones and aldehydes are important processes in organic chemistry. These activation strategies serve as a versatile platform for the construction of several domino reactions. READ MORE

5. 3. Organic Reactions i Organised Media

   Author : TOMASZ WITULA; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; mesoporous material; microemulsion; silica; lipase; Liquid crystal; alumina; entrapment.; heterogenized; titania; organic synthesis;

   Abstract : A common problem in synthetic organic chemistry is reactant incompatibility between lipophilic organic compounds and inorganic salts. The thesis reports an investigation of some organic reactions, involving incompatible substrate and nucleophile, performed in liquid crystalline phases and also in slurries of mesoporous materials with different symmetry.

6. 4. 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

7. 5. 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
