ChemInform Abstract: Aza-Michael Addition of Aliphatic or Aromatic Amines to α,β-Unsaturated Compounds Catalyzed by a DBU-Derived Ionic Liquid under Solvent-Free Conditions

A task-specific ionic liquid, 1,8-diazabicyclo[5.4.0]-undec-7-en-8-ium acetate has been successfully used as a catalyst for aza-conjugate addition of aliphatic or aromatic amines to various electron deficient alkenes under solvent-free conditions and at room temperature. The catalyst can be reused for six times without noticeable loss of activity.
