Abstract
A novel type of aromatic diamines (20 - 28) containing both oxygen and nitrogen donors were synthesized by Raney nickel-catalyzed hydrazine or amalgamated aluminum reduction of the corresponding nitro-compounds (3,12 - 19), which were prepared by condensation of N-substituted nitrogen mustards (4 - 11) with 2-nitrophenol in the presence of potassium carbonate in DMF at 80 °C for 6 h.
