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 Difluorophosphoric acid is an inorganic compound with the formula HPO2F2. It is a colorless liquid. The acid has limited applications, in part because it is thermally and hydrolytically unstable. It is prepared by hydrolysis of phosphorus oxyflu ...
