Synthesis of aminophenyl and methoxyphenyl perfluoroalkyl ketones

Lee, Hyeran,Czarny, Agnieszka,Battiste, Merle A.,Strekowski, Lucjan

, p. 221 - 224 (2007/10/03)

The title compounds are obtained by direct hydrolysis of the corresponding 2/4-perfluoroalkyl-substituted anilines and anisoles by the system AcOH/HBr/H2O/Al2O3. A two-step preparation of 2/4-perfluoroacylanilines involves the treatment of the 2/4-perfluoroalkylaniline with sodium ethoxide followed by hydrolysis of the resultant diethyl acetal with hydriodic acid.
