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

Reaction of pentafluoropyridine with nucleophilic heteroaromatics such as 4-(dimethylamino)pyridine, 4-(pyrrolidin-1-yl)pyridine, 4-(morpholin-4-yl)pyridine, 4-aminopyridine, and 3,4-diaminopyridine resulted in the formation of 4-hetarenium substituted tetrafluoropyridines. The 4-(dimethylamino)-pyridinium derivative underwent substitution reactions with isopropanolate, isopropanethiolate, and benzylthiolate
