The aromaticsubstitution of three representative N-alkyl trifluoromethyl imines 1a–c (R: a, benzyl; b, benzhydryl; c, methyl), obtained from primary alkyl amines and trifluoroacetaldehyde ethyl hemiacetal, was used to investigate the preparation of 1-aryl-2,2,2-trifluoroethylamines. In the presence of BF3·OEt2, the reaction of imine 1 with various aromaticcompounds proceeded smoothly at room temperature
