Abstract

Phosphonium amino acid ionic liquids were found to be useful for the copper-free and amine-free Sonogashira coupling reaction. A hydrophobic and lipophobic ionic liquid permitted easy separation of the product from ionic liquid and catalyst, and the recovered ionic liquid containing Pd catalyst could be reused.
