Iridium(III)-Catalyzed Synthesis of Benzimidazoles via C–H Activation and Amidation of Aniline Derivatives

Yunyun Li, Xifa Yang, Xingwei Li, Jintao Xia

Ir(III)-catalyzed synthesis of benzimidazoles has been realized under redox-neutral conditions by annulation of aniline derivatives with dioxazolones. The reaction proceeded via a C–H activation–amidation–cyclization pathway with a decent substrate scope.
