A practical copper-catalyzed oxidative dimerization of 2-oxindoles using di-tert-butyl peroxide as the radical initiator under base-free conditions was achieved, which not only provided an efficient route to prepare various 3,3′-bioxindoles, but also represented a simple strategy for C(sp3)–H functionalization/C–C bond formation. A radical mechanism was proposed based on the reaction results and controlling experiments.
