Thermodynamically- and kinetically-controlled Friedel–Crafts alkenylation of arenes with alkynes using an acidic fluoroantimonate(V) ionic liquid as catalyst

By employing superacidic fluoroantimonate ionic liquid (IL), [bmim][Sb2F11], as catalyst, not only thermodynamically-controlled but also kinetically-controlled Friedel–Crafts alkenylations of arenes with alkynes have been realized for the first time.
