Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A novel 8‐hydroxyquinoline functionalized PEG‐1000 bridged dicationic ionic liquid ([HQ‐PEG₁₀₀₀‐DIL][BF₄]) was synthesized and characterized. It was applied as an efficiently recyclable ligand for copper‐catalyzed <italic>N</italic>‐arylation of nitrogen‐containing heterocycles with aryl halides. The catalytic system could be easily recovered and reused for at least five runs without obvious loss of catalytic activity.</p> </abstract>
