Aplicação

o-Phenylenediamine can be used:
  • To prepare quinoxalines, benzimidazoles, and 1H-1,5-benzodiazepines by condensing with aryl aldehydes or ketones.
  • In the H2O mediated one-pot preparation of 1,2-disubstituted benzimidazoles by reacting with aldehydes in the presence of trimethylsilyl chloride.
  • In the copper-catalyzed synthesis of alkyne substituted quinoxalines by reacting with terminal alkynes.
  • In the preparation of 1,5-benzodiazepine derivatives by reacting with different ketones under neat reaction conditions via ytterbium trichloride catalyzed condensation reaction.
