Diastereoselective Ion Pairing of TRISPHAT Anions and Tris(4,4′-dimethyl-2,2′-bipyridine)iron(II)
摘要:
Two configurationally stable, chiral anions (TRISPHAT, 1) behave as efficient hosts that control the configuration of a configurationally labile iron(II) complex as the guest with high diastereoselectivity (>96 % de) upon ion pairing. The diastereoselectivity increases with decreasing solvent polarity.

Enantiomers of chiral tris(diimine)ruthenium(II) complexes can be separated on a polar chromatographic phase (SiO2) when associated with TRISPHAT counterions (2 equivalents).
