Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine Sulfate | HCID 24842 | — |
| Reactant | Aconitic anhydride | HCID 65163 | — |
| Solvent | Water | HCID 962 | — |
| Product | 2-(3,6-Dioxo-1,2,3,6-tetrahydropyridazin-4-yl)acetic acid | HCID 254428 | 85.4% |
Reaction Steps
A mixture of (2,5-dioxo-2,5-dihydro-3-furanyl)acetic acid (9 g) and hydrazine sulphate (7.2 g) in water was heated to reflux for 4 hours then allowed to cool to ambient temperature. The precipitate was filtered, washing with water then acetone. Drying in vacuo afforded a white solid (8.04 g, 82%).
