摘要：

The stereoselective photoreduction of rac-[Co(acac)(3)] (Hacac = acetylacetone) possessing molecular helicities [P(C-3) for Delta and M(C-3) for Lambda] by several ruthenium(II) photocatalysts having either P(C-3) or M(C-3) helical symmetry was successfully performed with a maximum enantiomeric excess of 38.7% at 40% conversion {to[Co(acac)(2)(H2O)(2)]} in EtOH-H2O (7:3) at 25 degrees C with an enantiomer rate ratio k(Delta)/k(Delta) of 5.2:1
