  摘要：

  N-methyl- and N-butylperfluoroarylamines are transformed by HNO3 into N-nitro-N-methyl- and N-nitro-N-butylperfluoroarylamines. These reactions were used to synthesise N-nitro-N-methylpentafluoroaniline and its p-CF3. -CN, -C6F5 substituted derivatives, N-nitro-N-methylperfluoro-2,4-xylidine, N-nitro-N-methyl-4-aminotetrafluoropyridine N-nitro-N-methyl 5-aminoperfluoroindane, N-nitro-N-methyl-2- aminoheptafluoronaphthalene. 4,4 ' -bis(N-nitro-N- merhylamino)octafluorobiphenyl from 4,4 ' -bis(N-methylamino)octafluorobiphenyl, N-nitro-N-n-butylpentafluoroaniline, N-nitro-N-n-butylperfluoro-p-toluidine, N-nitro-N-n-butyl-4-aminotetrafluoropyridine and N-nitro-bis( perfluoro-p-tolyl)amine. Tetrafluoro-p-benzoquinone and heptafluoro-p-toluquinol were obtained from N-methylpentafluoroanilinz and N-methylperfluoro-p-toluidine, respectively, under the action of a mixture of HNO3 and H2SO4 The X-ray crystal structure of N-nitro-N-methylperfluoro-p-toluidine was determined.

  N-Methyl-, N-n-butyl-, N-t-butylperfluoroarylamines undergo nitrosation with nitrous acid to give the corresponding N-nitroso derivatives. Perfluoroaryl groups were selected from the benzene, indane, biphenyl, naphthalene and pyridine series. According to H-1 and F-19 NMR spectra, N-nitroso-N-methyl derivatives of polyfluoroarenes, consist of E and Z isomers with the former prevailing. The more bulky n-butyl group promotes an increase in the formation of Z isomers. Only Z isomers have been obtained from N-t-butyl derivatives of perfluorinated 4-toluidine and 4-aminopyridine. The structure of the Z isomer of N-nitroso-N-methylperfluoro-4-toluidine is confirmed by X-ray data. (C) 2002 Elsevier Science B.V. All rights reserved.
