What is Hydrophilic diamine ligands for catalytic asymmetric hydrogenation of CO bonds about?

Asymmetric hydrogenations of phenylglyoxylate methyl ester and of acetophenone with catalytic amounts of iridium complexes containing hydrophilic chiral C 2 -symmetric diamine ligands is reported. E.e. values of up to 68% are observed for complete acetophenone hydrogenation in hydrophilic media. The use of such ligands allowed catalyst recovery without loss of activity and enantioselectivity in at least four hydrogenation cycles.
