unprecedented transitionmetal-freevisible light-induced autocatalytic intramolecularC–Hal (Hal = Cl, Br, I)/C–Hbondactivationleading to the formation of a new C–C bond between spatially converged benzene rings has been disclosed. In fact, irradiation of 5,6-diaryl-1-pyrrolo- [3,4- ]pyrimidine-2,4-diones with 395 nm LED light at room temperature promotes their cyclization to pyrimido[5′,4′:3,4]- pyrrolo[1
