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
Pentafluoroselenium hypofluorite can be produced from the reaction of selenium dioxide or selenium oxychloride with fluorine gas in the presence of silver difluoride catalyst. However, the reaction yield is low (14% [ 3 ] ), and it is hard to purify due to large amount of SeF 6 byproduct.

Relationship between survival of juvenile salmon and concentration of selenium in their tissues after 90 days (Chinook salmon [143]) or 45 days (Atlantic salmon [144]) exposure to dietary selenium. The 10% lethality level (LC10=1.84 μg/g) was derived by applying the biphasic model of Brain and Cousens [145] to only the Chinook salmon data. The ...
Selenium tetrachloride is the inorganic compound composed with the formula SeCl 4. This compound exists as yellow to white volatile solid. This compound exists as yellow to white volatile solid. It is one of two commonly available selenium chlorides , the other example being selenium monochloride , Se 2 Cl 2 .
At 120 °C SeO 3 reacts with selenium dioxide to form the Se(VI)-Se(IV) compound diselenium pentaoxide: [6] SeO 3 + SeO 2 → Se 2 O 5. It reacts with selenium tetrafluoride to form selenoyl fluoride, the selenium analogue of sulfuryl fluoride. 2SeO 3 + SeF 4 → 2SeO 2 F 2 + SeO 2. As with SO 3 adducts are formed with Lewis bases such as ...
