Highly Chemo- and Regioselective Reaction of Hydroxybenzenes in Acidic Ionic Liquid

) was reported for the first time. Aseries of oxa-Michael adducts and Friedel-Crafts alkylated products were synthesized with good yields. Theacidic ionic liquid could be easily recycled for at least 5 times with only minor loss in activity.Key Words : Acidic ionic liquid, Hydroxybenzenes, α,β-unsaturated compounds, Friedel-Crafts alkylation,oxa-Michael additionIntroductionThe reaction of hydroxybenzenes with α,β-unsaturatedcompounds has attracted a great deal of attention since itcould produce oxa-Michael adducts and Friedel-Craftsalkylated products.
