摘要：
Heterogeneous metal-complexes of the zero-valent nickel have been synthesized by ligand exchange between triphenylphosphine or hexaethyltriamidophosphine Ni(0) complex and chemically modified by method of immobilization support - silica, containing complex forming NPR2-group, where R is Ph or NEt2. The comparative characteristics of the activity of these catalysts and their homogeneous analogues in ethylene oligomerization are given. It is shown that various factors (pressure, temperature, molar correlation Al/Ni) do not significantly influence the selectivity of this process in the presence of investigated heterogeneous metal-complexes.
