Abstract
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.
