摘要：
A chiral, organometallic compound which, at a molecular level, has no C2 symmetry and comprises a carbon to carbon bond joining a chiral carbon atom to a carbon atom of a cyclopentadiene ring that is non-symmetrically substituted. Examples of such compounds include compounds of formula (I): ##STR1## wherein X.sup.1 and X.sup.2 are, independently, groups which are removable during a chemical reaction; M is titanium, zirconium or hafnium; and R.sup.1-8,11 are as specified in the description.
