Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | N-bromobutanimide | HCID 67184 | — |
| Reactant | Oxindole | HCID 321710 | — |
| Solvent | Acetonitrile | HCID 6342 | — |
| Product | 5-Bromo-2-oxindole | HCID 611193 | 91.8% |
Reaction Steps
2-Oxindole (1.3 g) in 20 mL of acetonitrile was cooled to −10° C. and 2.0 g of N-bromosuccinimide was slowly added with stirring. The reaction was stirred for 1 hour at −10° C. and 2 hours at 0° C. The precipitate was collected, washed with water and dried to give 1.9 g (90% yield) of 5-bromo-2-oxindole.
