The reaction of copper trifluoromethyl sulfide with diaryliodoniumsalts provides a straightforward pathway for the synthesis of aryl trifluoromethyl thioethers under mild reaction conditions and within short reaction times. High chemoselectivity was achieved by using mesityl as a leaving group. A large range of novel [(het)aryl](mesityl)iodoniumsalts underwent this reaction under the optimized conditions

While trifluoromethylthiolation of aryl halides has been extensively explored, the current methods require complex and/or air-sensitive catalysts. Reported here is a method employing a bench-stable Ni(II) salt and an iridium photocatalyst that can mediate the trifluoromethylthiolation of a wide range of electronically diverse aryl and heteroaryl iodides, likely via a Ni(I)/Ni(III) catalytic cycle.
