The intramolecular C(sp3)–H/C(sp2)–H cross-coupling of 1,3-dicarbonyl compounds has been achieved through Cp2Fe-catalyzed electrochemical oxidation. The key to the success of these dehydrogenative cyclization reactions is the selective activation of the acidic α-C–H bond of the 1,3-dicarbonyl moiety to generate a carbon-centered radical.
