Synthesis and Characterization of Bidentate NHC-CAryl Nickel(II) Complexes: Isocyanide Insertion To Form NHC-η2-iminoacyl Complexes

Synthesis and Characterization of Bidentate NHC-CAryl Nickel(II) Complexes: Isocyanide Insertion To Form NHC-η2-iminoacyl Complexes
Alison R. Fout, Joseph W. Nugent, Danielle L. Gray, Gabriel Espinosa Martinez
A bidentate monoanionic NHC-CAryl ligand framework was synthesized, and a host of Ni(II) complexes were prepared. Addition of isocyanides to these complexes led to the formation of NHC-η2-iminoacyl nickel complexes. These complexes were characterized by a suite of spectroscopic techniques, including X-ray crystallography. The η2-iminoacyl was shown to be displaced from the nickel center with oxidant and could then be reattached with reductant.
