Notes:
The main path of the interaction of chromium and nickel η3-allyl complexes and titanium tetrachloride is the transfer of allyl ligands to titanium with the concomitant reduction of TiCl4 to η-TiCl3 and the formation of the products initiating isoprene polymerization. The stereospecific effect of the system is because of the formation of bimetallic complexes with bridged metal - carbon bonds which are the most probable centers of stereospecific cis-1,4-polyisoprene chain propagation.
