Ring-contractive and -Closing Skeletal Rearrangement of 1,1’-Binaphthalene-2,2’-Diamines (Binams) Induced by an Iodine-Containing Oxidant: Synthesis of Spiro[Benzo[e]Indole-1,1'-inden]-2-amines and Application to an Aiee-active BF2 Complex
摘要:
An iodine-containing oxidant-induced ring-contractive and -closing skeletal rearrangement of 1,1'-binaphthalene-2,2'-diamines (BINAMs) to afford spiro[benzo[e]indole-1,11-inden]-2-amines has been discovered. Furthermore, a Spiro product was successfully transformed into a novel luminescent spirocyclic BF2 complex.

utilizes phenylboronic acids and arylazides as coupling agents in a redox-neutral environment, enabled by a synergistic nickel/photoredox catalytic system. This approach leverages a proton-coupled electron transfer mechanism to bypass the typical nitrene pathway associated with arylazides, which is prone to intramolecular rearrangement, C—H amination, and reductive hydrogenation. Notably, our method
