Aryl azides undergo clean reduction by copper nanoparticles in water in the presence of ammonium formate. The surface hydrogen on copper nanoparticles is considered to be the active reducing species. Various functionalized aryl azides and aryl sulfonyl azides are reduced to the corresponding amines with excellent chemoselectivity in high yields.
