iron-catalyzed cross-electrophile coupling of aryl chlorides with unactivated alkylchlorides via an iron/B2pin2 catalytic system has been developed. (Hetero)aryl chlorides undergo this transformation smoothly under mild conditions, furnishing the alkylated products with good efficiency. This protocol features excellent functional group compatibility and gram-scale synthesis, which also enables the late-stage functionalization
