Two C2-symmetric bis(sulfonamide) ligands containing fluorene-chiral (1R,2R)-cyclohexane- 1,2-diamine were complexed to Rh III(Cp*) and used as catalyst to reduce aromatic ketones. The corresponding chiral secondary alcohols were obtained in 87-100percent ee and 85-99percent yield, under asymmetric transfer hydrogenation (ATH) conditions using aqueous sodium formate as the hydride source. With acetophenone, 94percent ee and 86-97percent yield was achieved with substrate/catalyst (S/C) ratio of 10,000.
