Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Nitroaniline | HCID 7475 | — |
| Reactant | Phosphorus oxychloride | HCID 24813 | — |
| Product | N-(4-Nitrophenyl)phosphoramidic dichloride | HCID 12843950 | — |
Reaction Steps
To 300 ml of phosphorous oxychloride was carefully added 69 g (0.5 m) of 4-nitroaniline. The mixture was heated at reflux for 3 hours, then chilled to 10°. The crude product was collected by filtration, washed with ether and air-dried to give 93.6 g, m.p. 156.5°-157.5°.
