Preparation trialkylaluminiums

Looking at the preparation of supported metallocenes, synthesis of the metallocene on the carrier is found as well as fixing a metallocene either via functionality at the ligand or by direct reaction with the carrier, in both cases followed by activation with MAO or trialkylaluminium, but more common is heterogenization of the cocatalyst prior to mixing the modified carrier with the metallocene and activation by trialkylaluminium.

Other useful organometallic reagents for the preparation of tertiary stibines or related heterocyclic compounds are compounds of lithium, aluminum, tin, copper, zirconium, and other metals.In most cases, these metal compounds are reacted with antimony chlorides or bromides. Good yields of tertiary stibines were, however, also obtained by the interaction (equation 3) of trialkylaluminium reagents and tris(dimethylamino)stibine. ... [Pg.218]
