This study demonstrates that the alkenylation of arenes with alkynes catalyzed by binary acid Sc(OTf)(3)/TfOH can efficiently produce the desired adducts with high Z-selectivity and up to 90% yield.
Herein we report binary acid Sc(OTf)(3)/TfOH-catalyzed alkenylation of arenes with alkynes. In this system, the highenergy vinyl carbocations with activated and weakly coordinating trifluoromethanesulfonate anions by Lewis acid Sc(III) can undergo facile Friedel-Crafts reactions with arenes to give the desired adducts in up to 90% yield and with high Z-selectivity.
