Phosphorus (II) fluoride is a chemical compound with the empirical formula P 2 F 4 . The two phosphorus atoms in the +2 oxidation state are connected to one another via a single bond . Each phosphorus atom also has two bonds to fluorine atoms.
presentation
Phosphorus (II) fluoride can be produced by the reaction of phosphorodifluoride iodide with elemental mercury . Mercury (I) iodide precipitates here.
use
The compound can be used for the synthesis of difluorophosphines. So added phosphorus (II) fluoride in a gas phase reaction by UV irradiation to the triple bond of alkynes .
