Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrogen Bromide | HCID 260 | — |
| Reactant | 6-Methoxy-alpha-tetralone | HCID 14112 | — |
| Product | 6-Hydroxy-3,4-dihydro-1(2H)-naphthalenone | HCID 4679494 | — |
Reaction Steps
2 mols of 6-methoxy-1-tetralone are heated at 125° C. in 2 l of 48% strength aqueous hydrobromic acid for 3 hours. On cooling, the product precipitates and is filtered off with suction and dried. If necessary, it can be recrystallized from water.
