Friedel-Crafts reactions/acylation

Acidic chloroaluminate ionic liquids are able to generate acylium ions and are therefore ideally suited to Friedel-Crafts reactions. Acylation of mono-substituted aromatic compounds in acidic chloroaluminate ionic liquids leads almost exclusively to substitution at the 4-position on the ring [9] (Scheme 10.8). [Pg.200]
