Oxy-/amino-difluoromethylthiolation of β,γ-unsaturated oximes/hydrazones have been developed for construction of HCF2S-containing isoxazolines and pyrazolines by employing PhSO2SCF2H as difluoromethylthiolation reagent under mild conditions. Such transformations exhibit good functional group tolerance and scalability. Possible mechanisms are proposed.
