ABSTRACT:
There are provided enantiomerically enhanced chiral substituted cyclopentadienyl ligands, and compounds thereof, and a process for their making comprising contacting an optionally substituted fulvene having a prochiral carbon 6 with a lithium salt of an amine, amino acid or amide to effectuate enantioselective hydride addition to the carbon 6 of the fulvene so as to create a chiral center. There are further provided enantiomerically enhanced chiral organometallic complexes having one or more chiral substituted cyclopentadienyl groups.
