    successively trapped by pyrroles for the synthesis of heteroaromatic biaryls in moderate to excellent yields. The synthetically important photoredox catalytic C–H heteroarylation reaction works for a broad range of brominated electron-rich heteroarenes and chlorinated heteroarenes bearing electron withdrawing groups. In addition, this methodology was applied to the formal synthesis of a benzimidazole derivative
