Preparation
editSeleninyl 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
editSeleninyl 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
editSeleninyl fluoride have been used as specialty solvents.[7]
