Helicenes fused with hexafluorocyclopentene (HFCP) were synthesized by oxidative photocyclization of stilbene derivatives (the Mallory reaction). Of the newly‐obtained fluorinated helicenes, the [7]helicenes bearing one‐ or three‐HFCP units were structurally characterized by X‐ray crystallographic analysis. The attempted synthesis of [9]helicene fused with three HFCP units resulted in the unexpected formation of a novel double helicene consisting of [4]‐ and [6]‐helicenes sharing peripheral benzene rings. Optical properties and chiral resolutions of the newly obtained HFCP‐substituted helicenes are also described.
