The radical 1,5-chloropentafluorosulfanylation of vinyl cyclopropanes (VCPs) initiated by EtB/O affords allylic pentafluorosulfanyl/homoallylic chloride products through the ring-strain release of the cyclopropane. The VCP substitution pattern was investigated. The utility of this reaction was illustrated in post-transformation of the C═C bond by ozonolysis, giving access to valuable α-SF carbonyl compounds.
