Direct cross-dehydrogenative coupling of different inert C−H bonds is the most straightforward and environmentally benign method to construct C−C bonds. In this paper, we developed an iron-catalyzed intramolecular cross-dehydrogenative arylation (CDA) between benzylic C(sp3)H bond and aromaticC(sp2)H bond. From the readily available linear substrates, 1-arylnaphthalenes and 4-arylcoumarins can be
