[{Cu(IPr)}2(μ-OH)][BF4]: synthesis and halide-free CuAAC catalysis.
Résumé
The preparation under protic conditions of the first μ-hydroxo dicopper(I)–NHC complex is reported. Its application as a CuAAC catalyst was investigated, evidencing a remarkable enhancement of catalytic efficiency in the presence of 4,7-dichloro-1,10-phenanthroline and highlighting the beneficial effect of the absence of coordinating halides.
