Homogeneous ruthenium catalysts useful in the selective reduction of nitroaromatics to amines |
| abstract |
This invention concerns the use of solubilized homogeneous ruthenium catalysts to initially and sequentially reduce the nitro group in mononitroaromatic substrates to the corresponding amine. The reduction must be carried out in a two component mixture consisting essentially of the mononitroaromatic and a mononitro ortho-substituted polyalkylaromatic component. In order to minimize the reduction of said nitropolyalkylaromatic component, the reduction should be halted when between about 80 to 95 % of the mononitroaromatic substrate present is reduced to the corresponding amine. |
