Application

2,4-Dibromoaniline can be used as:
  • A starting material to synthesize acetylenic amine by reacting with trimethylsilylacetylene, which is used as a ligand to prepare the bis-amido complex of Ti(IV).
  • A substrate in the Pd-catalyzed ortho-selective cross-coupling reactions of dihaloarenes with Grignard reagents.
  • A reactant to prepare dialkyl-substituted aminoaryl sulfides using a Grignard reagent.
  • A starting material to synthesize substituted 2-mercapto benzimidazoles.
