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

rendering it valuable as both a polarity handle and a hydrogen bond donor/acceptor. Nevertheless, the poisonous nature of its free electron pairs makes sulfur containing substrates inaccessible for many catalytic protocols. Strong and (at low temperatures) irreversible chemisorption to the catalyst’s surface is in particular detrimental for heterogeneous catalysts, possessing only few catalytically active
