ResumoThe 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.
