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
