Phosphoramides
Phosphoramides are a class of phosphorus compounds with the formula O=P3-nn. They can be considered derivatives of phosphoric acid where OH groups have been replaced with an amino or R-substituted amino group. In practise the term is commonly confined to the phosphoric triamides, essentially phosphoramide and derivatives thereof. Derivatives with the general structures P2 or P2 are usually referred to as phosphoramidic acids.
Examples
- , the lightly studied parent monoamide of phosphoric acid.
- Phenyl phosphorodiamidate, a phosphoramide but also a phosphate ester, is used in agriculture to enhance the effectiveness of urea-based fertilizers.
- Hexamethylphosphoramide is a polar solvent.
