摘要：

A simple, efficient, and recyclable catalytic system of CuI-poly(ethylene glycol) (PEG) was developed for the N-arylation of imidazoles with aryl halides to afford corresponding N-arylimidazoles in good to excellent yields under mild conditions and free of any additional ligands and solvents. The isolation of the products was readily performed by simple extraction with ether, and the catalytic system could be reused without remarkable loss of activity even after six runs.
