Popis

General description

2,3-Diaminophenol is an aromatic diamine and forms Pd(II) and Pt(II) complexes. 2,3-Diaminophenol reacts with 2,4-pentanedione to yield the corresponding benzo[b][1,4]diazepinium salts. 2,3-Diaminophenol reacts with salicylaldehyde or 5-bromosalicylaldehyde in absolute ethanol to yield new unsymmetrical Schiff base.

Application

2,3-Diaminophenol was used:

• 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)
