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.
[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. The reaction of selenium dioxide and sulfur tetrafluoride also produces seleninyl fluoride. [4] SeO 2 + SF 4 → SeOF 2 + SOF 2

However, the reaction yield is low (14% [3]), and it is hard to purify due to large amount of SeF 6 byproduct. [4] Pentafluoroselenium hypofluorite can also formed from selenium oxyfluoride and fluorine gas in the presence of potassium fluoride.

Selenium tetrachloride is the inorganic compound composed with the formula SeCl 4. 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. SeCl 4 is used in the synthesis of other selenium compounds.
Tellurium tetrafluoride, TeF 4, is a stable, white, hygroscopic crystalline solid and is one of two fluorides of tellurium. The other binary fluoride is tellurium hexafluoride . [ 1 ] The widely reported Te 2 F 10 has been shown to be F 5 TeOTeF 5 [ 1 ] There are other tellurium compounds that contain fluorine, but only the two mentioned ...
