An efficient synthesis of benzimidazoles was developed by virtue of a recycled palladium catalyzed hydrogen transfer. The reaction can be carried out smoothly undermildconditions to give rise to a variety of benzimidazoles with good to excellent yields. The palladium catalyst could be recovered easily and reused six times with great catalytic activity.
