Preparation

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

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

Seleninyl fluoride have been used as specialty solvents.[7]
