Application

Friedel-Crafts Reactions.

Aluminum trifluoromethanesulfonate has been used for the Friedel-Crafts alkylation reaction of toluene with isopropyl and tert-butyl chlorides (eq 1), and for theacylationofbenzeneandtoluenewithacetylandbenzoylchlo- rides in low to moderate yields. Intramolecular Friedel-Crafts acylation of an aromatic compound with Meldrum's acid has also been reported using catalytic amounts of Al(OTf) 3 . Acylation of 2-methoxynaphthalene with acetic anhydride has been reported using Al(OTf) 3 and lithium perchlorate as an additive to afford the corresponding 6-acetylated adduct in 83% yield. Effective acylation of arenes with carboxylic acids has also been disclosed using polystyrene-supported Al(OTf)3.
