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.

摘要: Chiral organometallic compounds are provided which comprise certain non-symmetrically substituted cyclopentadiene complexed to a transition metal. The cyclopentadiene has a second coordinating group which also complexes the transition metal and is attached to the cyclopentadiene by means of a chiral connecting chain. Preferred transition metals include rhodium, ruthenium, iridium, cobalt, iron, manganese, chromium, tungsten, molybdenum, nickel, palladium, or platinum. These chiral organometallic compounds find use in asymmetric synthesis to produce chiral compounds.
