| Abstract: | Toluene solutions of titanium tetrachloride-triisobutyl aluminium varying in molar ratio from 1: 3 to 1: 30 are studied by electron paramagnetic resonance spectroscopy at 77 K. It is shown that the stepwise reduction of Ti(IV) to Ti(III) occurs under these conditions, resulting in the formation of TI 2 7+ and TI 2 6+ heterovalent compounds. A feasible mechanism for the interaction between TiCl4 and Al(i-Bu)3 is proposed. |
