Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Pyrrole | HCID 8027 | — |
| Reactant | 4-Formylbenzoic acid | HCID 12088 | — |
| Solvent | Propionic Acid | HCID 1032 | — |
| Product | meso-Tetra(4-carboxyphenyl)porphine | HCID 86278368 | 17.5% |
Reaction Steps
In refluxed propionic acid, 30 g of 4-carboxybenzaldehyde was reacted with 13.4 g of pyrrole to obtain 6.9 g of 5,10,15,20-tetra(4-carboxyphenyl)porphine. This porphine derivative was reacted with an aqueous solution containing four equivalents of sodium hydroxide to obtain tetrasodium 5,10,15,20-tetra(4-carbonatophenyl)porphine.
