Aromatic compounds, in the presence of 5 mol% Indium(III) trifluoromethanesulfonate, 40131as a Lewis acid catalyst, undergo a Friedel-Crafts reaction in water to give the ɑ-aryl-ɑ-hydroxy-2,2,2-trifluoropropionic ester: Synlett, 555 (2004). Several other metal triflates or triflic acid itself were less effective. Activated aromatics, e.g. indoles, undergo rapid Friedel-Crafts alkylation under solvent- and catalyst-free condtions: Tetrahedron Lett., 47, 2511 (2006)./n
