Ethylene oligomerization in the presence of catalytic systems based on nickel(II) formazanates

The influence of the temperature, the pressure, the Al/Ni molar ratio, and the position of chlorine-containing substituents in formazan ligands on the reaction kinetics and the product composition in the ethylene oligomerization catalyzed by thea system based on nickel(II) formazanates and ethylaluminium dichloride has been studied. It has been shown that effective metal complex catalyst systems can be prepared via varying the nature and the position of the substituents in the ligands. © 2010 Pleiades Publishing, Ltd.The work wais supported by the Russian Academy of Sciences under the Presidium Basic Research Pro gram of fundamental investigations, project no. 18 of Presidium of RAN, and by the assignment of the Min istry of Education and Sciences of the Russian Feder ation, for performing the r(research assignment work according to the topic 1.2.06)
