Selenium tetrafluoride (Se F 4) is an inorganic compound.It is a colourless liquid that reacts readily with water. It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than a gas.
Seleninyl fluoride can be produced by the reaction of selenium oxychloride and potassium fluoride. [3] 2 KF + SeOCl 2 → 2 KCl + SeOF 2. It can also be produced by the reaction of selenium tetrafluoride with water or selenium dioxide. [2] SeF 4 + H 2 O → SeOF 2 + 2 HF SeF 4 + SeO 2 → 2 SeOF 2
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
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]

Despite the low reactivity of the tetrafluoroborate anion in general, BF − 4 serves as a fluorine source to deliver an equivalent of fluoride. [2] The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known example of such a reaction. [3]
