An unprecedented defluorocyclization of perfluorobutyl tetralones with Na2S·9H2O was developed for the synthesis trifluoromethyl 1,2-dithioles, which provided chemists novel access to biologically and pharmaceutically relevant organofluorides. Successive C(sp3)–F bond functionalization at perfluoroalkyl chain is vital formation four C–H/C–S/S–S bonds a five-membered S-heterocycle assembly. Cheap, weakly toxic, odorless inorganic sulfide acts as both disulfurating precursor hydrodefluorinating reagent in this tandem multi-bond-interconverting reaction.
