Abstract
Activated-copper powder is an efficient catalyst for the N-arylation of heterocycles with aryl halides and can be reused several times. The reactions can proceed smoothly in water by using LiOH as base and give the corresponding products in good yields. The protocol shows good tolerance toward various functional groups.
