The synthesized have been bimetallic catalyst complex based on aluminum, 1,2-dichloroethane, and salts of various transition metal compounds and the structure of which were determined by modern methods of analysis and with their participation  oligomerization process alpha-olefins was carried out. It is found that bimetallic complexes exhibit high stable catalytic activity in the oligomerization processes, thereby yield, increases the molecular weight and physico-chemical properties of the resulting products are improved are improved.
