A metal‐ and catalyst‐free thiyl‐radical‐mediated activation of alkanes is described. Tetrafluoropyridinyl disulfide is used to perform thiolation of the C−H bonds under irradiation with 400 nm light‐emitting diodes. The key C−H activation step is believed to proceed via hydrogen‐atom abstraction effected by the fluorinated thiylradical. Secondary, tertiary, and heteroatom‐substituted C−H bonds can
