The annual worldwide production of UF6 is very large and this compound is not used. Consequently, it could be interesting to find some applications as organic reagent. UF6 could be considered as an oxidizer of various functions. However, it seems also present some possibilities as a fluorinating reagent in mild conditions.

Transformation of carbon–hydrogenbonds to carbon–fluorine bonds at saturated secondary and tertiary carbon sites by electrophilic aliphatic substitution processes is possible using either elemental fluorine or fluorinating reagents of the N–F class.

achieved by reaction with either elemental fluorine or Selectfluor™, an electrophilic fluorinatingreagent of the N–Fclass. An electrophilic mechanism is envisaged. On prolonged reaction, the strongly acidic reaction medium that is formed upon substitution of hydrogen by fluorine when Selectfluor™ is used as the fluorinatingreagent, promotes loss of fluoride from the initial fluorinated product.
