without any directing group by cross-dehydrogenative coupling between unactivatedC(sp3)–H and C(sp3)–Hbonds has been established for the first time, which provides a good complement to C(sp3)–Hactivation reactions and expands the field of Fe-catalyzed C–H functionalizations. Many different C(sp3)–Hbonds in cyclic alkanes, cyclic ethers, and toluene derivatives can be used as coupling partners. Mechanistic
