| Abstract: |                      Ni(II), Ni(I) Ni(O)      .  , ,   , Ni(O) Ni(I) - Ni(I) Ni(II) Ni(O).
The interaction of organoaluminium compounds with phosphine complexes of Ni(II), Ni(I) and Ni(0) has been studied under the conditions of catalytic propylene dimerization. The active complexes are formed from Ni(II) compounds, the regeneration of the latter is ensured by repeated reduction, oxidation of Ni(0) to Ni(I), and by disproportionation of Ni(I) into Ni(II) and Ni(0). |
