Seleninyl fluoride is an oxyfluoride of selenium with the chemical formula SeOF₂.

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]
