Zusammenfassung:FIELD: organic synthesis. SUBSTANCE: claimed method comprises oligomerization of ethylene in the presence of catalyst system comprising zirconium oxocarboxylate $$$ wherein R is $$$ fatty acid fraction, diethylaluminium chloride and carbon tetrachloride. $$$ molar ratio is 0.3-1.25 and $$$ molar ratio is 10-20. EFFECT: improved yield of $$$ olefins and lower content of polymer by-product. 1 tbl
