copper catalyst. Both intermolecular and intramolecular reactions included tandem processes, in which selective iodination of sp3 C–H bond at the α-position of ester under mild conditions was demonstrated for the first time. Tandem reactions involving sp3 C–H activation via α-iodo ester intermediate under copper catalysis efficiently provided more than 20 novel azole compounds, and free radicals were not
