A novel poly(ethylene glycol) grafted triethylamine functionalized dicationic ionic liquid has been prepared and characterized. It was successfully used as an efficient catalyst for the three-component synthesis of 2-amino-2-chromene derivatives in water. The simple workup, mild reaction conditions, wide substrate flexibility, excellent yields, and environmental friendliness are notable advantages of this protocol. In addition, the catalyst could be reused several times without appreciable reduction of catalytic activity.
