Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | N-bromobutanimide | HCID 67184 | — |
| Reactant | Ethyl 2-acetylbut-2-enoate | HCID 53941670 | — |
| Solvent | Carbon Tetrachloride | HCID 5943 | — |
| Product | Ethyl 2-Methyl-3-furoate | HCID 261900 | 24% |
Reaction Steps
A mixture of 3.12 g (0.02 mole) ethyl 2-acetyl-2-butenoate and 3.56 g (0.02 mole) N-bromosuccinimide in 50 ml of carbon tetrachloride was heated at reflux for 19 hours. After cooling, the insoluble succinimide was removed by filtration and the solution concentrated by rotary evaporation. Distillation of the crude product gave 0.73 g (24%) of ethyl 2-methyl-3-furoate, bp 87°-9° C. (20 mm).
