| | Aluminum trifluoromethanesulfonate Usage And Synthesis |
| Chemical Properties | White powder | | Uses | Lewis acid used as a catalyst for Friedel–Crafts, ketalization, nucleophilic substitution, hydroalkoxylation, methoxycarbonyla- tion, rearrangement, and epoxide ring-opening reactions. | | Uses | Aluminum trifluoromethanesulfonate is used in pharmaceutical intermediates. | | Preparation | Can be prepared from aluminum trichloride and tribromide by heating with triflic acid in anhydrous conditions. Preparations from triethylaluminum, aluminum carbide, and aluminum isopropoxide have also been described. | | Reactions | 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.
