Application
TCI Practical Example: Bromination Reaction Using Dibromoisocyanuric Acid.
-
Used Chemicals
-
- 2,6-Dinitrotoluene
- Dibromoisocyanuric Acid (= DBI) [D3753]
- conc. H2SO4
-
Procedure
-
Dibromoisocyanuric acid (433 mg, 1.51 mmol) was added to a solution of 2,6-dinitrotoluene (500 mg, 2.75 mmol) in conc. sulfuric acid (3 mL) and stirred at room temperature for 1.5 hours. Then the solution was poured into iced water. The aqueous layer was extracted with ethyl acetate and the organic layer was dried over anhydrous sodium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (dichloromethane:hexane = 0:100 - 20:80) to give 5-bromo-2-methyl-1,3-dinitrobenzene as a white solid (501 mg, 70% yield).
-
Experimenter’s Comments
-
The reaction mixture was monitored by UPLC.
Both bromo groups of DBI can be used for bromination.
