Phosphoryl fluoride (commonly called phosphorus oxyfluoride) is a compound with the chemical formula . It is a colorless gas that hydrolyzes rapidly.

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
