Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3-Iodophthalic acid | HCID 238231 | — |
| Solvent | Acetic Anhydride | HCID 7918 | — |
| Product | 3-Iodophthalic anhydride | HCID 282071 | 65.2% |
Reaction Steps
A solution of 3-iodophthalic acid (0.9 g, 3.08 mmol) in acetic anhydride (5 mL) was heated to reflux under nitrogen overnight. After cooling, the solvent was removed in vacuo and the residue purified by trituration with ethanol to give 4-iodo-2-benzofuran-1,3-dione (0.55 g, 65%).
