Heteroatomic Chalcogen Cations

Several approaches have been used for the synthesis of heteroatomic chalcogen cations, including (a) direct oxidation of a mixture of two chalcogens with oleum, MF5 (M = As, Sb) or transition metal halides, (b) reaction of a chalcogen with a homoatomic cation of another chalcogen and (c) compro-portionation of the homoatomic cations of two different chalcogens.

Similar, but less stable, selenium homocycles, as well as mixed sulfur-selenium related heterocycles formed by heteroatom replacement, are also well docnmented. Cationic chalcogen homocycles are also known and have been reviewed. ... [Pg.5998]
