Abstract

The NF fluorinating agent F-TEDA-BF4 dication salt (Selectfluor™) 1 dissolves in imidazolium-based ionic liquids [emim][OTf] 7,[emim][BF4] 8,[bmim][PF6] 9 and [bmim][BF4] 10 (assisted by sonication), providing a convenient medium for fluorination of arenes under essentially acid-free conditions in a simple set-up (no volatile solvent; simple extraction of the aromatics without aqueous work-up), from which the ionic liquid can be easily recycled ...
