Nickel Complexes with N-heterocyclic Carbene Ligands: Chemistry and Homogeneous Catalytic Reactions
Prof. Michael J. Chetcuti (University of Strasbourg)

Simple nickel(II) complexes with N-heterocyclic carbene (NHC) ligands show a large spectrum of activity in homogeneous catalysis, that includes Suzuki-Miyaura coupling, aldehyde, ketones and imine hydrosilylation, and -ketone arylation. In addition, they are able to promote C–H activation reactions; in addition, the unusual labilization of a cyclopentadienyl ligand bound to an 18-electron Ni complex has been demonstrated with such nickel-NHC complexes. After a review of some earlier research, recent results that include the isolation of a 14-electron T-shaped nickel complex, the catalytic activity of sulfur-containing NHC complexes, alkene hydroboration catalysis and the synthesis of Ni-NHC ligands grafted onto calixarenes will be presented.
