Palladium-catalyzed Substitution of Ketone or Aldehyde Bearing Aryl Triflates by Amines or Amides
Various aryl triflates, bearing ketone or aldehyde groups, were evaluated for palladium-mediated introduction of an amino group at the triflate position in the presence of various phosphine ligands. BINAP was best for secondary amines, MOP-type ligand for primary or small secondary amines and Xantphos for primary or cyclic secondary amides. No ligand was found effective for acyclic secondary amides.
