✦ Synopsis

C 2 -symmetric bis(sulfonamide) ligands derived from chiral trans-(1R,2R)-cyclohexane-1,2-diamine were immobilized on silica gel and on polystyrene resin, and complexed to Rh III Cp*. The resulting complexes were used as catalysts in the asymmetric transfer hydrogenation (ATH) of acetophenone. The chiral secondary alcohol was obtained in high yields (>99%) and enantioselectivities (92%) with aqueous sodium formate as the hydride source. The immobilized catalysts were recycled with no loss in activity.
