  Thermocontrolled benzylimine–benzaldimine rearrangement over Nafion-H catalysts for efficient entry into α-trifluoromethylbenzylamines

  摘要：

  Nation-H and Nation SAC-13 are efficient solid Bronsted acid catalysts for the preparation of trifluoromethyl ketimines from benzylamines and trifluoromethylated ketones in high yields. A finely tuned benzylimine-benzaldimine rearrangement by facile 1,3-hydrogen shift has been achieved for the formation of fluorinated benzaldimines in high yields by careful optimization of reaction conditions including attempts under microwave conditions and a flow system. These alpha-trifluoromethylated benzaldimines are efficient precursors for pharmaceutically important alpha-trifluoromethylated benzylamines, accessed through their direct acid hydrolysis.
