摘要: Abstract It has been shown that replacement of Cl atoms by I and Br leads to decrease in the activity catalytis systems TiCl 3 -AlEt owing number active centres. This is probably due fact a group titanium bound halogen bridges, not single atom, involved act. The most effective way enhancing isospecificity centre induce iodine-containing compound act upon crystal surface. However, no simple correlation between stereospecificity systems, ion radii anions distances M-M M-X was found.
