Phosphoryl fluoride
Phosphoryl fluoride is a compound with the chemical formula. It is a colorless gas that is hydrolyzed in aqueous solution, passing through difluorophosphate and monofluorophosphate to give ultimately orthophosphate.
Synthesis and reactions
Phosphorus oxyfluoride is prepared by partial hydrolysis of phosphorus pentafluoride.Phosphorus oxyfluoride is the progenitor of the simple fluorophosphoric acids by hydrolysis. The sequence starts with difluorophosphoric acid:
The next steps give monofluorophosphoric acid and phosphoric acid:
Phosphoryl fluoride combines with dimethylamine to produce dimethylaminophosphoryl difluoride and difluorophosphate and hexafluorophosphate ions. The tendency of phosphoryl fluoride toward disproportionation into those ions is not, of course, paralleled by the chloride.
