Title: Crystal structures and polymerization catalytic properties of 1,1,2,2-tetramethyldisilane-bis(3-t-butyl-η5-cyclopentadienyl) titanium and zirconium dichlorides
Abstract: Abstract The title complexes Me 4 Si 2 (1-C 5 H 3 -3- t Bu) 2 MCl 2 (M=Ti, 1 ; M=Zr, 2 ) have been prepared by reaction of Li 2 Me 4 Si 2 (C 5 H 3 -3- t Bu) 2 with MCl 4 ·2THF in refluxing THF. Rac / meso ratio of about 2/3 was obtained for the titanocene complex 1 . But for the zirconocene 2 , only meso isomer was obtained. The crystal structures of meso - 1 and meso - 2 were determined. Their catalytic properties for ethylene polymerization have also been studied with MAO as a cocatalyst.
