Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol | HCID 887 | — |
| Reactant | 4-Amino-3-Nitrophenol | HCID 3758882 | — |
| Catalyst | Palladium | HCID 23938 | — |
| Product | 2,3-Diaminophenol | HCID 579937 | 95% |
Reaction Steps
To a solution of 3-nitro-4-aminophenol (4.6 g, 30 mmol) in methanol is added 500 mg of Pd/C. A hydrogenation reaction is performed at room temperature for 2 hours and then terminated. The Pd/C is removed by filtration to obtain 4.1 g of 3-hydroxy-o-phenylenediamine, with a yield of 95%.
