Dataset of Triple Regioselective Functionalization of Cationic [4]Helicenes via Iridium-Catalyzed Borylation and Suzuki Cross-Coupling Reactivity

In essentially one-pot, using Ir- and subsequent 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, i.e. fluorescence quantum yields and lifetimes. ECD and CPL signatures are observed up to the far-red domain, in particular with arenes prone to aggregation, simply introduced by the late-stage functionalization procedure.
