- W2007145422 abstract "Abstract Fluoroaromatic compounds are a yew important group of intermediates for medicinal and agricultural chemicals. Many methods and reagents were developed for the fluorofunctionalisation of aromatic ring, but only few of them meet at least three basic requirements: selectivity, mild reaction conditions and high yield. We now report a new method for regiospecific and high yield fluorofunctionalisation of aromatic molecules under simple reaction conditions which is based on the reactions of CsSO 4 F with aryl alcohols in acetonitrile suspension, α-Hydroxy awl derivatives (aryl: 1-naphthyl; 9-antryl; 9-phenanthryl) were readily and regiospecifically converted to 1-fluoronaphthalene, 9-fluoroantracene or 9-fluorophenanthrene in over 80% yield. Benzyl alcohol derivatives with electron-donating substituent on the orto or para position were also transformed regiospecifically into orto or para substituted fluorobenzenes. 9-Methyl-9-hydroxyfluorene was transformed by CsSO 4 F to 2-fluoro-2′-acetyl biphenyl and 9-phenyl-9-hydroxyxanthene to 2-fluoro-2′phenonyl diphenylether." @default.
