1. 1. Novel Applications of Benziodoxole Reagents in the Synthesis of Organofluorine Compounds

   Författare :Nadia O. Ilchenko; Kálmán J. Szabó; Cristina Nevado; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trifluoromethylation; hypervalent iodine; Togni reagent; difluorination; iodofluorination; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis concerns method development of new synthetic routes by applying electrophilic hypervalent iodine reagents, such as trifluoromethyl-benziodoxole (Togni reagent) and fluoro-benziodoxole. The first project involved the addition of an oxygen moiety and trifluoromethyl group across double and triple bonds (both groups derived from the hypervalent iodine reagent). LÄS MER

3. 2. Development of Catalytic ElectrophilicTrifluoromethylation and Fluorination Methods

   Författare :Nadia Ilchenko; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is focused on development of new catalytic, electrophilic fluorination and trifluoromethylation methods of alkenes. These reactions were carried out using hypervalent trifluoromethyl and fluoroiodine reagents.The first project involved copper catalyzed oxytrifluoromethylation of terminal alkenes and alkynes.
