It is prepared by treating selenium with sulfuryl chloride (SO 2 Cl 2). [10] Selenium reacts with fluorine to form selenium hexafluoride: + In comparison with its sulfur counterpart (sulfur hexafluoride), selenium hexafluoride (SeF 6) is more reactive and is a toxic pulmonary irritant. [11]
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. The reaction of fluorine gas and Hg(OSeF 5) 2 produces SeOF 6 in much higher yield and with less SeF 6. [3]

The sulfoxide in sulfur chemistry is represented in selenium chemistry by the selenoxides (formula RSe(O)R), which are intermediates in organic synthesis, as illustrated by the selenoxide elimination reaction. Consistent with trends indicated by the double bond rule, selenoketones, R(C=Se)R, and selenaldehydes, R(C=Se)H, are rarely observed.

A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+. Many molecules fit this formula. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6 ), which is a byproduct of the mining of phosphate rock .
