2. 1. Development of new Fluorination Methods Directed to Fluorine-18 Labelling

   Author : Miguel Ángel Cortés González; Kálmán J. Szabó; Guosheng Liu; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluorine-18; late-stage; labelling; nucleophilic; electrophilic; fluorination; positron emision tomography; PET; hypervalent iodine; benziodoxole; metal-free; DBU; copper; palladium; rhodium; carbene; organisk kemi; Organic Chemistry;

   Abstract : This thesis deals with the development of new fluorination reactions and their application to fluorine-18 labelling. Fluorine-18 labelled compounds are employed as tracers in Positron Emission Tomography (PET), which is a powerful non-invasive imaging method in medical diagnostics. READ MORE

4. 2. Metal Mediated Synthesis. Synthetic and Mechanistic Investigations of Conjugate Addition and Reductive Amination

   Author : Anders Johansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; halosilane; all-trans-geranylgeraniol; copper reagent; primary amines; S -geranylcitronellol; iminium salt; alfa; cuprate; beta-unsaturated; lithium iodide; borane dimethyl sulfide complex; reductive amination; conjugate addition;

   Abstract : The thesis is divided into two separate parts, one treating conjugate addition and the other reductive aminations. The first part of the thesis is concerned with organocopper promoted conjugate addition to .alfa.,. READ MORE

5. 3. Transformations of Nitrosoarenes and Alkynyl Enones : Selective Synthesis of Nitrogen-Containing Compounds

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; alkynyl enones; catalysis; copper; halogenation; heterocycles; nitrosoarenes; perfluoroalkylation; trifluoromethylation; organisk kemi; Organic Chemistry;

   Abstract : The nitrogen atom plays a unique role in organic chemistry. It is abundantly found in organic materials and is responsible for the activity of many biologically relevant compounds. READ MORE

6. 4. Management and Treatment of Organotin and Metal Contaminated Dredged Sediment

   Author : Anna Norén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tributyltin TBT ; electrolysis; metals; stabilization and solidification S S ; life cycle assessment LCA ; dredged sediment; copper Cu ; multicriteria analysis MCA ; zinc Zn ; Fenton’s reagent;

   Abstract : Modern society is dependent on international trade and most traded goods are transported by sea. To enable this, regular dredging must be done to maintain water depth in ports and waterways, resulting in large quantities of often contaminated sediment that must be handled. READ MORE

7. 5. New Reactions with Allyl- and Allenylboron Reagents : Transition-Metal-Catalyzed and Transition-Metal-Free Carbon-Carbon Bond Formation Processes

   Author : Dong Wang; Kálmán J. Szabó; Jianbo Wang; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon-carbon bond formation; cross-coupling; organoboron compound; allylboron reagent; allylation; transition metal; metal carbene; allenylboron reagent; transition metal free; diazo compound; tosylhydrazone; quinone; organisk kemi; Organic Chemistry;

   Abstract : Organoboron compounds have been widely used in carbon-carbon bond formation reactions in organic synthesis and catalysis. This thesis is focused on cross-coupling reactions of allyl-, allenylboronic acids and their ester derivatives via transition metal catalysis or transition-metal-free processes. READ MORE
