We report on hydroarylation reactions of arenes with olefins under very mild conditions catalyzed heterogeneously by aluminum chlorofluoride (ACF; AlClxF3?x, x≈0.05–0.25). The reactions of benzene and toluene with ethylene or propylene proceed with high conversions to afford various alkylated arenes. For cyclohexene and 1-hexene, the reactions require higher temperatures and the conversions are lower. ACF also catalyzes the hydroarylation of 1,3,5-trifluorobenzene and pentafluorobenzene with ethylene and propylene. The alkylations of arenes with non-fluorinated olefins resemble typical Friedel–Crafts chemistry to give rise to Markovnikov regioselectivity. The reaction of CF3CH=CH2 with benzene proceeds with anti-Markovnikov regioselectivity to give the fluorinated olefin PhCHCH=CF2 and the alkylation product PhCH2CH2CF3 as products of C?F and C?H activation.

The Friedel-Crafts reaction of 1,1,1-trifluoropropene with benzene and its derivatives was accomplished in the presence of fluorine-containing acid catalysts.The reaction proceeded at the terminal carbon atom of the olefin to give 3,3,3-trifluoropropylated aromatic compounds.The scope and limitations of this reaction were examined.This substituent was found to be ortho- and para-directing.Keywords - Friedel-Crafts reaction; trifluoropropene; trifluoropropyl; Nafion-H; hydrogen fluoride; boron trifluoride; tetrafluoroboric acid; benzene; trifluoropropylation
