From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐
