Abstract

Bis (trifluoroalkylsulfonylimino) trifluoromethanesulfonic acid has demonstrated remarkable catalytic ability in the electrophilic acylation of aromatic substrates. Various perfluoroalkyl substituted aroyl chlorides are employed in Friedel–Crafts acylation typically using 1mol% of catalyst.
