[Cu(NHC)(OR)] (R = C(CF3)3) complexes for N-H and S-H bond activation and as pre-catalysts in the Chan-Evans-Lam reaction

The synthesis, isolation, and full characterization of a series of NHC-copper perfluoro-alkoxide complexes are reported. Their exceptional stability resides with the steric hindrance of the nonafluoro-tert-butyl alkoxide moiety, which exhibits...
