Abstract
Aliphatic and aromatic nitro compounds were selectively reduced to their corresponding amino derivatives in good yields using formic acid and Raney nickel. This system is found to be compatible with several sensitive functionalities such as halogens, -OH, -OCH3, -CHO, -COCH3, -COC6H5, -COOH, -COOEt, -CONH2, -CN, -CH=CH-COOH, -NHCOCH3. The reduction can be carried out not only with HCOOH but also with HCOONH4.
