| Abstract: | Eight chiral iridium complexes were synthesized from ( R ) (+) or ( S ) (-) phenylethylamine and Ir(COD)Cl] 2(COD=1,5 cyclooctadiene). The complexes were used as enantioselective catalysts in the asymmetric hydrogen transfer reactions of acteophenone. It was found that the highest optical yield was up to 35.7% e.e.. |
