   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Samarium II iodide; reduction; single electron transfer; nitro group reduction; mechanistic study; bond cleavage; deoxygenation; additives; toluenesulfonyl deprotection; defluorination.;

   Sammanfattning : This thesis describes the development of methods using divalent samarium reagents in organic synthesis. The main focus is placed on functional group reductions, but reductive formation of carbon-carbon bonds has also been investigated. LÄS MER

3. 2. Lanthanide-mediated C-F Bond Activation Method Development and Mechanistic Investigation

   Författare :Mario Janjetovic; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-F bond activation; fluorine chemistry; lanthanides; single-electron transfer reagent; Lewis acid; chemoselectivity; synthetic method; catalysis;

   Sammanfattning : The use of transition-metals and main-group Lewis acids has proven to be an outstanding source for activation and subsequent functionalization of fluorinated compounds. However, the first is mainly limited to C(sp2)–F bonds which partially are activated by an adjacent heteroatom, and the latter is limited to simple C(sp3)–F bonds due to particularly strong Lewis acid character.
