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.

Selenium tetrabromide exists in two polymorphs, the trigonal, black α-SeBr 4 and the monoclinic, orange-reddish β-SeBr 4, both of which feature tetrameric cubane-like Se 4 Br 16 units but differ in how they are arranged. [1]
