P-IODOBENZYL BROMIDE - Reference Information
| Application | 4-iodobenzyl bromide is an organic intermediate, which can be obtained by bromination of 4-iodotoluene. It has been reported that it can be used to prepare isoxazolamide derivatives of artemisinin keto acid. |
| prepare | add bromine (3.6ml,69.9mmol) and 30% hydrogen peroxide (5.2g,45.9mmol) water (70ml) solution to 4-iodotoluene (10.0g,45.9mmol) dichloromethane (70ml) solution sequentially at room temperature, heat the reaction solution, and stir vigorously under reflux for 10 hours (bath temperature: 50 ℃). Transfer the reaction solution to a separatory funnel, add chloroform (40ml) and water (20ml) to the funnel to delaminate, and wash the organic layer 3 times with water (150ml). In turn, the organic layer was washed with 0.5% sodium bisulfite aqueous solution (150ml) and water (150ml), and the solvent was removed under reduced pressure (bath temperature: 25 ℃). Before completely removing the solvent, add toluene (50ml) to the mixture, and then concentrate the mixture. This process is carried out twice. The mixture was concentrated to dry solid and the residue was dried under vacuum to prepare 4-iodobenzyl bromide (12.1g). |
