Eheparations for seleninyl fluoride and selenium tetrafluoride that require only Se02 and SP4 are very convenient and are identical to that used for the synthesis of Tep4. Other methods of preparation include partial fluorination of elemental... 

Because of this straightforward synthesis of seleninyl fluoride, xenon bis[pentafluorooxoselenate(VI)] can now be prepared easily. The latter was prepared initially by the reaction of XeFj and H[Sep50], which results from a time-consuming multistep synthesis. ...

All compounds are handled in a dry box. Xenon difluoride (8.5 g, 0.05 mole) is placed in a l(X)-mL stainless steel pressure vessel [Hoke], Seleninyl fluoride (4.4 g, 0.033 mole) is placed into a Kel-F or FEP (fluoroethylene propylene copolymer) test tube-shaped tube and inserted into the reaction vessel in an upright position. The vessel is closed and then cooled to —78° (methanol/Dry Ice) and placed in a horizontal position on a mechanical shaker. After being shaken for 24 hr at room temperature, the vessel is attached to a vacuum line and cooled to — 20°, and the volatile material (Xe) is transferred under dynamic vacuum into a trap cooled to —196°. The vessel is filled with dry argon (or nitrogen) and opened in the dry box. The impure pale yellow liquid is transferred... 

An improved method of synthesis of fluoroxypentafluoroselenium SeFs-OF has been developed, viz. direct fluorination of the solid (KSeOFj ) formed by the addition of potassium fluoride to seleninyl fluoride. Treatment of the fluoroxy-compound with perfluorocyclopentene, carbon monoxide, and sulphur tetrafluoride has yielded the new compounds cyclo-CsF -O-SeF, SeFs O COF, and SeFs-O SFj, respectively.
