method for the synthesis of the corresponding mononuclear Ni(II) alkoxo or amido complexes. These
complexes undergo addition reactions to heterocumulenes (CO2, PhNCO, PhNCS), leading to the formal
insertion of these molecules into the Ni−O or Ni−N bonds. The dialkylamido complexes decompose
through β-hydrogen elimination processes, which selectively afford η2-imine Ni(0) compounds.
