Reaction of AsF5 and SbF5 with elemental selenium and tellurium and with TeF4 and Te(OTeF5)4

Arsenic and antimony pentafluorides are versatile oxidizing agents that have been used to prepare a variety of new species. The reactions of these reagents with Se and Te and with mixtures of these two elements have been studied in some detail and a variety of cationic species of these elements have been prepared. Among the species containing both selenium and tellurium these include Te2Se22+, Te2Se42+, Te2Se62+ and Te2Se82+. The reactions have …
