Palladium fluoride

Palladium fluoride is the name of a series of binary compounds of palladium and fluorine. These include:

• Palladium(II) fluoride or palladium difluoride, PdF₂
• Palladium(II,IV) fluoride or palladium trifluoride, PdF₃. It is not palladium(III) fluoride (which is unknown), and is often described as palladium(II) hexafluoropalladate(IV), Pd^II[Pd^IVF₆][1]
• Palladium(IV) fluoride, or palladium tetrafluoride, PdF₄
• Palladium(VI) fluoride, or palladium hexafluoride, PdF₆, which is calculated to be stable[2]

Palladium-fluorine coordination complexes have been developed to catalyse the synthesis of aryl fluorides, which are otherwise difficult to make.[3][4]
