Phosphoramide
Chemical compound
Phosphoramide is a chemical compound with the molecular formula O=P(NH2)3. It is a derivative of phosphoric acid in which each of the hydroxyl groups have been replaced with an amino group. In bulk, the compound is a white solid which is soluble in polar solvents.
01Chemical properties
Phosphoramide arises from the reaction of phosphoryl chloride with ammonia. In moist air, it hydrolyzes to an ammonium salt:
- 2 H2O + O=P(NH2)3 → [NH4]+[PO2(OH)(NH2)]− + NH3
It reacts with sodium hydroxide with loss of ammonia:
- NaOH + O=P(NH2)3 → Na+[PO2(NH2)2]− + NH3
The related thiophosphoryl triamide compound S=P(NH2)3 was made from the reaction of thiophosphoryl chloride with ammonia.
02Phosphoramides
Phosphoramide is also the parent compound for a range of derivatives called phosphoramides. An example compound is the polar solvent hexamethylphosphoramide (HMPA).
