Ruthenium(ii)-catalyzed α-fluoroalkenylation of arenes via C–H bond activation and C–F bond cleavage

Abstract

Ru(II)-Catalyzed efficient α-fluoroalkenylation of arenes has been realized with gem-difluorostyrene as an olefinating reagent. This coupling system is efficient with a broad substrate scope, providing 1,2-diaryl-substituted monofluoroalkenes with good to excellent regio- and stereoselectivities under silver-free conditions.
