Triple Regioselective Functionalization of Cationic (4) Helicenes via Iridium‐Catalyzed Borylation and Suzuki Cross‐Coupling Reactivity

to related objects

Abstract: In essentially one‐pot, using Ir‐ and Pd‐catalysis, tris (arene)‐functionalized cationic [4]helicenes are synthesized with full regioselectivity and enantiospecificity starting from a trivial precursor (17 examples). This poly‐addition of aryl groups improves key optical properties, that is, fluorescence quantum yields and lifetimes. Electronic circular dichroism and circularly polarized luminescence signatures are observed up to the far‐red domain, in particular with additional arenes prone to aggregation.
