Synthesis of ?2-enaminoester using new phosphonium ionic liquids

摘要

The development of an environmentally benign green methodology for the synthesis of β- enaminoester using new phosphonium ionic liquids as catalyst. Ethyl acetoacetate, ammonium acetate and catalytic amount of ionic liquid in acetonitrile was carried out at 25°C and 50°C to yield β-enaminoester.
