ABSTRACT:
A racemic mixture of a chiral, silicon bridged transition metal metallocene, which is substantially free of meso isomer, is precipitated directly from a reaction mixture as it is formed by reacting an organic solvent solution of an alkali metal salt of a silicon bridged ligand with a transition metal tetrahalide-ether complex.
