An effective protocol for iron‐catalyzed biaryl syntheses by couplingchlorostyrenes with aryl Grignard reagents requires only mild reaction conditions and tolerates various functional groups. The underlying activation of deactivated aryl chlorides proceeds through a rate‐determining coordination of the catalyst to the vinyl substituent and subsequent haptotropic migration along the conjugated π system
