| Abstract
| - Fluoride displacement from the complex Ni(Me)(F)(dippe) by LiOR or LiNRR‘ provides an efficientmethod for the synthesis of the corresponding mononuclear Ni(II) alkoxo or amido complexes. Thesecomplexes undergo addition reactions to heterocumulenes (CO2, PhNCO, PhNCS), leading to the formalinsertion of these molecules into the Ni−O or Ni−N bonds. The dialkylamido complexes decomposethrough β-hydrogen elimination processes, which selectively afford η2-imine Ni(0) compounds.
