| Abstract: | Bromination of deactivated aromatics has been studied in detail. Some deactivated aromatics such as trifluoromethylbenzene could be brominated with good results by using KBrO 3 H 2 SO 4 as brominating reagent. The effects of reaction conditions, such as concentration and quantity of sulfuric acid, reaction temperature and different deactivated groups are investigated. |

| Keywords: | deactivated aromatic bromination KBrO 3 H 2 SO 4 |
