文摘

The first examples of isolable and structurally characterized Cu(I)−CF₃ complexes are reported. N-Heterocyclic carbene (NHC)-supported copper tert-butoxide complexes reacted with Me₃Si−CF₃ to afford new (NHC)Cu−CF₃ complexes whose structures were dependent on whether or not the C₄−C₅ positions of the five-membered NHC rings were saturated. In situ generated (SIiPr)Cu−CF₃ cleanly transferred its trifluoromethyl group to a number of organic halides under mild conditions.
