Rpl + Spl)-[Rh(η5-4,7-dimethylindenyl-CH2CH(Ph)PPh2-kP)(η2-CH2CH2)] as 61:39 and 15:85 mixtures of diastereomers. The complexes were isolated in optically pure form by column chromatography. The stereochemical configuration of one of the diastereomers was determined by X-ray crystallography. The complexation of L2 was studied in different solvents and with several Rh precursors and diastereomeric excesses up to
