Synthesis

edit

2,4,6-Tribromoaniline can be prepared by treating bromine water with aniline in a solution of acetic acid or dilute hydrochloric acid:[1]

 
By reacting bromine with aniline in water, a white precipitate immediately forms and that is 2,4,6-tribromoaniline

Reactions

edit

Diazotization, then reaction with ethanol to replace the diazonium group with hydrogen, gives 1,3,5-tribromobenzene.[2]
