N-Arylation of azaheterocycles with aryl and heteroaryl halides catalyzed by iminodiacetic acid resin-chelated copper complex

Iminodiacetic acid resin-chelated copper(II) complex is effective in cross-coupling reactions between azaheterocycles and aryl or heteroaryl halides, providing N-arylated products in good to excellent yields. The copper catalyst is air stable and can be readily recovered and reused with minimal loss of activity for three runs.
