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.
SeOF 6 can also oxidize potassium iodide into iodine. [1] It explodes upon reacting with ethylene, and the reaction with perfluorocyclopentene produces F 5 SeOC 5 F 9. [4] SeOF 6 reacts with sulfur tetrafluoride to produce thionyl fluoride, thionyl tetrafluoride, sulfuryl fluoride, selenium hexafluoride and F 5 SOSeF 5. [4]

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 ...
C 6 H 13 CO 2 H + 2 SF 4 → C 6 H 13 CF 3 + 2 SOF 2 + HF. The formation of the trifluoromethyl derivative sometimes competes with formation of tetrafluoroalkyl ethers, which arise from the reaction between difluoromethyl cation and acyl fluoride. [11] [12] Sulfur tetrafluoride can be used to fluorinate polymers efficiently.
