describes an efficient Rh(III)-catalyzed oxidative C–H/C–H cross-coupling between acyclic enamides and heteroarenes. This cross dehydrogenative coupling (CDC) reaction offers advantages, including excellent regioselectivity and stereoselectivity, good functional group compatibility, and a broad substrate scope. Mechanistically, Rh(III)-catalyzed β–C(sp2)–H activation of acyclic enamides is proposed
