European Journal of Organic Chemistry, Volume 29, Issue 13, 13 April 2026.Fluoro substituents on a benzene ring linked to a 2‐bromoaryl group enables the selective activation of one of its C─H bonds via Pd‐1,4‐migration. Then, Pd‐catalyzed direct coupling with heteroarenes produces C2’‐heteroarylated 1,1′‐biaryls. In this reaction, the new C–C bond arises from the functionalization of two C─H bonds.
