Baasner, B.,Klauke, E.
, p. 553 - 564 (1982)
Anhydrous hydrogen fluoride serves as an excellent agent for introducing fluorine into organic compounds, as a solvent and a catalyst with Friedel-Crafts activity.A number of chlorine/fluorine exchange reactions which occur in HF are described, some of which have involved surprising rearrangement processes.New reactions, in which the catalytic action of hydrogen fluoride are utilized, are also discussed.
