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.
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. The reaction of selenium dioxide and sulfur tetrafluoride also produces seleninyl fluoride. [4] SeO 2 + SF 4 → SeOF 2 + SOF 2
Selenium tetrafluoride is a laboratory-scale fluorinating agent. The only stable chlorides are selenium tetrachloride (SeCl 4) and selenium monochloride (Se 2 Cl 2), which might be better known as selenium(I) chloride and is structurally analogous to disulfur dichloride.
[4] 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]

A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
Sulfur tetrafluoride is a chemical compound with the formula S F 4. It is a colorless corrosive gas that releases dangerous hydrogen fluoride gas upon exposure to water or moisture. Sulfur tetrafluoride is a useful reagent for the preparation of organofluorine compounds , [ 3 ] some of which are important in the pharmaceutical and specialty ...
