A simple and high-efficient C-N cross-coupling method of aryl halides with nitrogen-containing heterocycles was reported.Using 10%(molar fraction) Cul as catalyst and 1.1 eq.NaH as base,aryl iodides.aryl bromides and many aryl chlorides could efficiently react with nitrogen-containing heterocycles,and high yield of N-arylated products were obtained.The ligand-free copper salt catalyst system was stable in air and could be reused.
