The complexes [(eta(6)-p-(PrC6H4Me)-Pr-i)Ru(NO(2)pesa)Cl] 2, [(eta(6)-p-(PrC6H4Me)-Pr-i)Ru(oxazsa)Cl] 3 and [(eta(6)-p-(PrC6H4Me)-Pr-i)Ru(pepy)Cl] 4, chiral in the chelate ligand and chiral at the ruthenium atom, have been prepared by reaction of [(eta(6)-p-(PrC6H4Me)-Pr-i)RuCl2](2) with the anions of the (S)-configured bidentate N,O- and N,N-ligands. [(eta(6)-p-(PrC6H4Me)-Pr-i)Ru(pesa)I] 5 was synthesized by halide exchange. The diastereomer ratios of compounds 2-4 with respect to the stereogenic ruthenium atom are in CDCl3 2a:2b=81:19, 3a:3b=77:23 and 4a:4b=61:39. Compound 5 is obtained diastereomerically pure.
