Abstract:the formation of an active propadiene polymerization catalyst in the system Ni(acac)2, C3H4, (i-Bu)3Al was studied by means of 1H NMR and ESR spectroscopy. At low temperature two types of nickel(I) complexes could be trapped, probably intermediates in the formation of the catalyst, which is proposed to be a tetrahedrally or octahedrally coordinated paramagnetic Ni(II) complex.
