The ligand-free trifluoromethylation of arylboronic acids with a Ph(2)SCF(3)(+)OTf(-)/Cu(0) system has been carefully investigated. Aryl-, alkenyl- and heteroarylboronic acids with a variety of functional groups were suitable substrates for this reaction. It is suggested that a CuCF(3) species is formed under the reaction conditions.
Zhang et al. (Sat,) studied this question.
