Application

1-Ethylpyridinium tetrafluoroborate [EPy][BF4} is an ionic liquid that can be used as:
  • A reaction medium in the Morita-Baylis-Hillman (MBH) reactions of acrylonitrile with 4-nitrobenzaldehyde to yield MBH adducts.
  • A solvent in the Diels-Alder reactions of isoprene with dienophiles.
  • A component of a binary mixture, which is employed in the solute-solvent interaction studies using vitamins like nicotinic acid and ascorbic acid.
