Conclusions
-
1.
Anils of polyfluorobenzophenones are oxidized by trifluoroperacetic acid in methylene chloride at 20°C forming polyfluoro-substitutedα,α,N-triarylnitrones. A condition of this direction for the reaction is the presence on the carbon atom of the azomethiae bond of a least one pentafluorophenyl group.
-
2.
Oxidation of the anil of pentafluorobenzaldehyde with trifluoroperacetic acid led to the formation of pentafluorobenzoic acid anilide and pentafluorobenzaldehyde.
