Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phthalic Anhydride | HCID 6811 | — |
| Catalyst | palladium(II) acetate | HCID 167845 | — |
| Product | 5,5'-Bi-2-benzofuran-1,1',3,3'-tetrone | HCID 75494 | — |
Reaction Steps
20 g (135 mmol) of phthalic anhydride was heated at 80° C. for 5 hours in the same manner as in Example 1 except that palladium acetate was omitted. As a result, a BPDA was not formed.
