Reduction with Sodium Borohydride-Transition Metal Salt Systems. I. Reduction of Aromatic Nitro Compounds with the Sodium Borohydride-Nickelous Chloride System

Abstract

The reduction of aromatic nitro compounds with the sodium borohydride-nickelous chloride system was examined. Aromatic nitro compounds afforded primary amines in high yield without by-products. Similarly, nitroso-, azoxy-, azo- and hydroxylaminobenzene were reduced with sodium borohydride-nickelous chloride to give aniline.
