Seleninyl fluoride is an oxyfluoride of selenium with the chemical formula SeOF2.
Preparation
[edit | edit source]Seleninyl fluoride can be produced by the reaction of selenium oxychloride and potassium fluoride.[3]
- 2 KF + SeOCl2 → 2 KCl + SeOF2
It can also be produced by the reaction of selenium tetrafluoride with water or selenium dioxide.[2]
- SeF4 + H2O → SeOF2 + 2 HF
- SeF4 + SeO2 → 2 SeOF2
The reaction of selenium dioxide and sulfur tetrafluoride also produces seleninyl fluoride.[4]
- SeO2 + SF4 → SeOF2 + SOF2
Reactions
[edit | edit source]Seleninyl fluoride reacts with xenon difluoride to form Xe(OSeF5)2.[4]
- 3 XeF2 + 2 SeOF2 → Xe(OSeF5)2 + 2 Xe
It reacts with fluorine gas and potassium fluoride to form pentafluoroselenium hypofluorite.[5][6]
- SeOF2 + KF → K+[SeOF3]− —F2→ K+[SeOF5]− —F2→ KF + SeOF6
Uses
[edit | edit source]Seleninyl fluoride have been used as specialty solvents.[7]
