Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Nitrogen oxide (N2O4) | HCID 25352 | — |
| Reactant | 3-Bromo-1-benzofuran | HCID 640589 | — |
| Product | 3-Bromo-2-nitro-1-benzofuran | HCID 13509842 | — |
Reaction Steps
To a stirred 80 g. sample of solid 3-bromobenzofuran is added a large excess of dinitrogen tetraoxide. The mixture liquifies within 5 minutes. After 2 hours, the mixture is triturated with ethanol and filtered to provide yellow crystals of 3-bromo-2-nitrobenzofuran. The product is identical to the product of Example 1 according to infrared spectral analysis.
