Abstract

AbstractA general and convenient method for the direct transition‐metal‐free intermolecular chlorodifluoromethylthiolation of a variety of unactivated alkenes and alkynes has been described. This methodology exhibits good functional group tolerance and is operationally simple. Mechanistic studies indicated an electrophilic substitution mechanism, and the strong electrophilic difluoromethylthiolating reagent HCF2SCl was generated in situ under standard reaction conditions. The developed protocol fulfils the requirements of sustainable and green chemistry.
