Azole derivatives were synthesized by iron-catalyzed oxidative reactions of azoles and ethers in good to excellent yields. A wide variety of azoles and ethers were selectively transformed into the corresponding oxidative coupling products under neutral reaction conditions.

cross-dehydrogenative coupling reaction of α-C(sp3)–H bonds adjacent to a hetero atom with various azoles has been developed, which provides an alternative method for constructing C–N bonds with high atom efficiency. This new protocol requires no metal catalyst and it provides ready access to a wide range of N-alkylated azole derivatives in moderate to excellent yields by using commercially available PhI(OAc)2
