A concise metal‐free method for synthesizing 6‐alkylthiophenanthridines from 2‐isocyanobiaryls and disulfides proceeding through thiolation of isocyanides and intramolecular radical aromatic cyclization is reported. This process involves SS/C(sp 2 )H bond cleavage and CS/CC bond formation, which tolerates a wide range of substrates and gives good to excellent yields.
