AbstractFluoride displacement from the complex Ni(Me)(F)(dippe) by LiOR or LiNRR‘ provides an efficient 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.
