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]
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]

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.

): The compound has an extremely low pK a of −28 and is 10 quadrillion (10 16) times stronger than pure sulfuric acid. [30] Fluoroantimonic acid is so strong that it protonates otherwise inert compounds like hydrocarbons. Hungarian-American chemist George Olah received the 1994 Nobel Prize in chemistry for investigating such reactions. [99]
