Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Phenylacetophenone | HCID 9948 | — |
| Reactant | Bromine | HCID 24408 | — |
| Solvent | Chloroform | HCID 6212 | — |

Reaction Steps
In chloroform (200 ml) is dissolved 2-phenylacetophenone (25.5 g) and thereto is added a solution of bromine (22 g) in chloroform (100 ml) and the mixture is stirred at room temperature for 5 hours and then allowed to stand overnight. After distilling off chloroform, to the resulting residue is added methanol. The precipitates are filtered off and the filtrate is subjected to a silica gel chromatography and eluted with chloroform. The eluates are collected and distilled to remove chloroform to give 2-bromo-2-phenylacetophenone (26 g) as an oily substance.
