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)

Pd(II) and Pt(II) new complexes with simple aromatic diamines were synthesised and characterised with the aim of studying their possible antitumour activity. The aromatic diamines chosen were 2,3-diaminotoluene (2,3 dat), 3,4-diaminotoluene (3,4 dat), 4,5-diaminoxylene (4,5 dax) and 2,3-diaminophenol (2,3 dap).

2,3-Diaminophenol 4, 3,4-diaminophenol 5, 4-methoxy-1,2-diaminobenzene 6, 3,4-diaminobenzenethiol 7, 2,3-diaminobenzoic acid 8, and 3,4-diaminobenzoic acid 9 were reacted with 2,4-pentanedione to yield the corresponding benzo[b][1,4]diazepinium salts, respectively. The hydroxy-benzo[b][1,4]diazepinium salts 17 and 18 do not form mesomeric betaines (MB) on deprotonation.
