Elucidation of the function of these reagents is the reason the Cossee- Arlman mechanism was postulated. Their performance is limited by the limited number of defects that prevent the formation of the octahedral coordination complexes that usually form on their surfaces. An important technique when using these substances is "tuning," in which a semi-poison allows selective initiation of the beta-hydride elimination at a given mass; that can be done as the reactions these compounds are meant to cause are often terminated by competing beta-hydride eliminations. These reduce the activation energy for creation of syndiotactic or isotactic polypropylene and polyacetylene because they are used to create stereoregular chains of alpha-olefins. They are titanium based and function by organo-aluminum complexes. For ten points, name these important catalysts used to polymerize one-alkenes.
