Application

4-(Trifluoromethoxy)aniline was used in the synthesis of:
  • side-group liquid-crystalline polymethacrylates with fluorine-containing mesogens
  • derivatives of 3-(quinolin-3-yl)acrylates
  • series of novel Shiff bases, via condensation with pyridinecarboxaldehydes in the presence of molecular sieves
