A practical and efficient method for the direct trifluoromethylthiolation of unactivated C(sp3)H bonds by AgSCF3/K2S2O8 under mild conditions is described. The reaction has a good functional‐group tolerance and good selectivity. Initial mechanistic investigations indicate that the reaction may involve a radical process in which K2S2O8 plays key roles in both the activation of the C(sp3)H bond and

A straightforward silver-mediatedoxidative decarboxylative radical trifluoromethylthiolation reaction of aliphatic carboxylic acid is described. This reaction operates under mild conditions and allows the synthesis of various valuable alkyltrifluoromethylthioethers from abundant alkyl carboxylic acids and convenient nucleophilic AgSCF3 reagent. It provides a practical and efficient approach for the
