Starting from 2-arylbenzimidazoles and aryl halides, an efficient palladium-based catalytic method for the synthesis of benzimidazole-fused phenanthridines, e.g., I, has been developed. This reaction sequence is comprised of an intermol. C-H arylation and intramol. aerobic oxidative C-H amination, which involved the rupture of two C-H bonds, one C-X bond, and one N-H bond in one pot. The PdII-PdIV-PdII and PdII-Pd0-PdII catalytic cycles worked together under the reported conditions to generate phenanthridines with diverse substituents.
