- Abstract:
-
The chemistry of a series of ansa-bridged ethylene-bis(hexamethylindenyl) zirconium and hafnium complexes has been explored. Treatment of EBI*Li2·THF0.38 with MCl4· THF2 (M = Zr, Hf) gives rac-EBI*MCl2 (rac-2, rac-3) and meso-EBI*MCl2 (meso-2, meso-3) (M = Zr and Hf), respectively. The rac-and meso-isomers can be separated by fractional crystallization. meso-EBI*ZrMe2 (meso-4) can be prepared by alkylation of meso-2 with MeLi·LiBr. The molecular structures of rac-and meso-2 and rac-and meso-3...
