has been developed. The reaction proceeds under metal-free reaction conditions with high efficiency and broad functional group tolerance, which offers a general and straightforward access to benzo[b]fluorenones under metal-free conditions. The preliminary mechanistic studies revealed the possible involvement of a Meyer–Schuster rearrangement combined with an oxidative radical cyclization.
