N-Arylation of nitrogen heterocycles with aryl halides and arylboronic acids catalyzed by cellulose supported copper(0)

Cellulose supported copper(0) catalyst was prepared and employed for the N-arylation of nitrogen heterocycles with a variety of aryl halides and arylboronic acids to afford the corresponding coupled products in good to excellent yields without using external ligands or additives as promoters. The catalyst was recovered by simple filtration and reused for several cycles. (c) 2006 Elsevier B.V. All rights reserved.
