unprecedented transition metal-free visible light-induced autocatalytic intramolecular C–Hal (Hal = Cl, Br, I)/C–H bond activation leading 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
一种前所未有的无过渡金属可见光诱导的自催化分子内 C-Hal (Hal = Cl、Br、I)/C-H 键活化,导致空间会聚的苯环之间形成新的 C-C 键。事实上,在室温下用 395 nm LED 光照射 5,6-二芳基-1-吡咯并-[3,4-]嘧啶-2,4-二酮可促进其环化为嘧啶基[5',4':3, 4]-吡咯并[1,2-]菲啶-12,14(11,13)-二酮,产率高,卤素性质微不足道。
