Application

Butyraldehyde can be used as a reactant in the:
  • Reductive amination of various nitroarene derivatives to synthesize mono-N-alkylated aniline derivatives.
  • Ionic liquid-catalyzed Knoevenagel condensation with active methylene compounds to synthesize substituted electrophilic alkenes.
  • NiCl2-catalyzed synthesis of α-aminonitriles by reacting with amines and trimethylsilyl cyanides.
