The relative reactivity of the hexafluorides of S, Se, and Te follows the order TeF 6 > SeF 6 > SF 6, the latter being completely inert toward hydrolysis until high temperatures. SeF 6 also resists hydrolysis. [3] The gas can be passed through 10% NaOH or KOH without change, but reacts with gaseous ammonia at 200 °C. [8]
However, the reaction yield is low (14% [3]), and it is hard to purify due to large amount of SeF 6 byproduct. [4] Pentafluoroselenium hypofluorite can also formed from selenium oxyfluoride and fluorine gas in the presence of potassium fluoride. [4] [5] SeOF 2 + KF → K + [SeOF 3] − — F 2 → K + [SeOF 5] − — F 2 → KF + SeOF 6

AsF 5 + KF → KAsF 6. Also, it can be synthesized by the action of hydrofluoric acid on arsenic pentafluoride in the presence of potassium perbromate: [4] KBrO 4 + 3HF + 2AsF 5 + KF → KAsF 6 + AsF 6 [H 3 O] Also, potassium hexafluoroarsenate is synthesized by treating arsenic pentachloride and potassium chloride in the presence of ...

SeF 4 + SeO 2 → 2 SeOF 2. The reaction of selenium dioxide and sulfur tetrafluoride also produces seleninyl fluoride. [4] SeO 2 + SF 4 → SeOF 2 + SOF 2. Reactions.
Molybdenum hexafluoride has few uses. In the nuclear industry, MoF 6 occurs as an impurity in uranium hexafluoride since molybdenum is a fission product of uranium.. The semiconductor industry constructs various integrated circuits through chemical vapor deposition of molybdenum hexafluoride. [4]
