Hydrophobic Frechet-type dendritic chiral 1,2-diaminocyclohexane-Rh(III) complexes have been applied in the asymmetric transfer hydrogenation of ketones in water using HCOONa as hydrogen source. The catalysts were found to be finely dissolved in the liquid substrates in the aqueous mixture and exhibited high catalytic activity and enantioselectivity (52-97% ee). The catalytic loading could be decreased
