The syntheses of chiral anion receptors based on rhenium (I) and ruthenium (II) with amide bipyridine ligands are reported. The rhenium (I) hosts were prepared in moderate to high yields by co-ordinating chiral bipyridine ligands to a Re (CO) 3Br centre. The ruthenium (II) receptors were synthesised via the chiral building blocks Λ-and Δ-[Ru (bpy) 2 (py) 2] 2+ or by chromatographic resolution on a SP Sephadex C-25 cation exchanger. Chiral purity ...
