Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4'-Bromo-2-nitrobiphenyl | HCID 21857647 | — |
| Solvent | Triethyl phosphite | HCID 31215 | — |
| Product | 2-Bromo-9H-carbazole | HCID 12717089 | 40% |
Reaction Steps
Around bottom flask was charged with 4′-bromo-2-nitrobiphenyl (100 mmol) and triethyl phosphite (100 mL) and set to reflux under a nitrogen atmosphere for 24 hours. Upon cooling, the solvent was distilled off under vacuum, and the crude product was recrystallized from hot toluene to give 2-bromo-9H-carbazole in 40% yield.
