ChemInform Abstract: Dioxygenyl Hexafluoroantimonate: A Useful Reagent for Preparing Cation Radical Salts in Good Yield.

Abstract In Freon solvents at temperatures ranging from ‐120 ° to ‐145 °C, the title reagent (I) cleanly converts (II)‐(IV) to the corresponding cation radical salts in yields of 97, 89 and 40%, resp. (the salt prepared from (IV) cannot be isolated).
