Abstract

The reaction of Δ/Λ-[Ru(bpy)2(py)2]2+ with a prochiral sulfide ligand, and then in situ oxidation, provide the corresponding Δ-[Ru(bpy)2{(R)-OSO-iPr}]+ and Λ-[Ru(bpy)2{(S)-OSO-iPr}]+ (OSO-iPr = 2-isopropylsulfonylbenzonate) enantiomers in a yield of 83% with 98% ee. The chiral sulfoxides were obtained by treatment of the sulfoxide complexes with TFA in a yield of 90% with 88–91% ee.
