2,3-Diaminophenol

• in one-pot microwave assisted synthesis of amino-1,5-benzoxazepines and hydroxyl-1,5-benzodiazepines
• in the electrosynthesis of poly(2,3-diaminophenol) via electro-oxidation
• in a synthesis of tetradentate Schiff base complexes via reaction with salicylaldehyde or 5-bromosalicylaldehyde and metals such as Mn(III), Ni(II) and Cu(II)

Example 1: 11-(3-Chlorophenyl)-6-hydroxy-3,3-dimethyl-2,3,4,5,10,11-hexahydro-dibenzo[e][1,4]diaza Synthesis of 2-amino-dibenzo[e][1,4]diazepine-1-one Step 1: A mixture of 2-amino-3-nitrophenol (10.0 g, 64.9 mmol) with 10% Pd/C catalyst in ethanol (150 mL) was hydrogenated for 12 h at room temperature. Upon completion of the reaction, the reaction mixture was degassed with nitrogen followed by filtration to remove the catalyst and washing the catalyst well with ethanol. The filtrate was evaporated to afford 8.0 g (99% yield) of the target product 2,3-diaminophenol as a black solid.
