Malononitrile → 2-(1-Ethoxypropylidene)malononitrile
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Malononitrile | HCID 8010 | — |
| Reactant | Ethyl orthopropionate | HCID 66995 | — |
| Product | 2-(1-Ethoxypropylidene)malononitrile | HCID 231470 | 93% |
Reaction Steps
Triethyl orthopropionate (1000 g, 5.5 mole) and malononitrile (363 g, 5.5 mole) were combined and refluxed for 5 hours. The reaction mixture was cooled to room temperature and the residue was distilled at 125°-143° C. (3-7 mm Hg) to afford 768.1 g (93%) of (1-ethoxypropylidene)malononitrile as an orange liquid.
