Peroxy-acidoxidation of NN-disubstituted 4-aminotetrafluoropyridines occurred with rearrangement of the expected intermediate N-oxide to give the NNO-trisubstituted hydroxylamines. The 2,4-bis-(NN-disubstituted amino)trifluoropyridines gave the 2-mono-N-oxide only. The oxidation of NN-dialkylamino-3-chlorotrifluoro and -3,5-dichlorodifluoropyridines was also studied and the influence of the amino-
