Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Amino-3-Nitrophenol | HCID 3758882 | — |
| Catalyst | Palladium | HCID 23938 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 3,4-Diaminophenol | HCID 2772970 | 105.9% |
Reaction Steps
4-Amino-3-nitrophenol (1.09 g, 7.072 mmol) was dissolved into ethanol (50 ml). Palladium on charcoal (10%, 220 mg) was added and the mixture was stirred for 3.5 h under hydrogen atmosphere. The reaction mixture was filtered over Celite® and concentrated to afford 138a (930 mg, 100% yield) as a dark brown solid.
