Application
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.
