A new, electrophilic difluoromethylthiolating reagent N-difluoromethylthiophthalimide 3 was developed. Reagent 3 can be readily synthesized in four steps from easily available starting materials phthalimide and TMSCF2H. N-difluoromethylthiophthalimide 3 is a powerful electrophilic difluoromethylthiolating reagent that allows the difluoromethylthiolation of a wide range of nucleophiles including aryl/vinyl

An efficient copper‐promoted difluoromethylthiolation of aryl and heteroaryldiazoniumsalts is described. The reaction is conducted under mild reaction conditions and various functional groups were compatible. In addition, reactions of heteroaryldiazoniumsalts such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl, and pyrazolyl diazoniumsalts occurred smoothly to afford the medicinally

A highly efficient Pd‐catalyzed difluoromethylthiolation of aryl chlorides, bromides and triflates is described. A variety of arylhalides with common functional groups were difluoromethylthiolated in moderate to excellent yields. Furthermore, several natural, drug and material molecules containing an aryl chloride, bromide, and phenol unit were successfully difluoromethylthiolated, thus providing

A palladium-catalyzed difluoromethylthiolation of heteroaryl halides and triflates under mild conditions was described. A vast range of heteroaryl halides such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl and pyazolyl halides could be difluoromethylthiolated efficiently, thus providing medicinal chemists with new tools for their search of new lead compounds for drug discovery. Likewise
