Fluoroarylation ofgem-difluorostyrenes through a Pd-catalysed aryl C–H bond activation cascade

A novel fluoroarylation of gem -difluorostyrenes with AgF and (hetero)arenes through a Pd( ii )-catalysed C(aryl)–H activation cascade was developed, constituting an efficient method to access CF 3 -substituted fluorenes and 1,1-diarylmethanes.
