Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Isoprene | HCID 6557 | — |
| Reactant | 1,3-Diethyl 2-oxopropanedioate | HCID 69105 | — |
| Catalyst | zinc(II)iodide | HCID 9883512 | — |
| Product | HCID 565258 | HCID 565258 | 3.5% |
Reaction Steps
To 50 g (0.70 mol) isoprene was added 25 g (0.14 mol) diethylketomalonate and 0.78 g (2.4 mmol) zinc iodide. The reaction mixture was stirred at room temperature for 48 hours. The excess isoprene was removed under vacuum. Flash chromatography in 20:1 hexanes:ethyl acetate yielded 1.2 g of oil.
