hexafluoroisopropanol (HFIP) as an additive promotes intramolecular radical cascade cyclization to afford cyclopropanated furans. Molecular dioxygen in the air serves as a redoxcatalyst in this reaction which is proposed to proceed through a radical cation intermediate generated by single‐electron transfer (SET) from a phototransient dienone to oxygen. By changing the solvent from isopropanol to HFIP
