Реферат:
A variety of heterobinuclear Ni(I) complexes of the general formula [LNiI(μ-X1)(μ-X2)AlR2] formed upon the activation of the [LNiIIBr2] (1) ethylene polymerization catalyst (L = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) with AlR3 (R = Me, Et, and iBu), AlR2Cl (R = Me, Et), and MMAO were detected and characterized in situ by EPR and 1H NMR spectroscopy. The nature of the bridging groups X1 and X2 (X1, X2 = R, Br, or Cl) depends on the nature and excess of the cocatalyst used. The catalyst systems displaying various [LNiI(μ-X1)(μ-X2)AlR2] species were compared in ethylene polymerization. Possible roles of Ni(I) species in the catalytic process are discussed.
