Chiral analysis of alfa-diimine Ru(II) and Fe(II) complexes by capillary electrophoresis using sulfated cyclodextrins as stereoselectors
Sázelová, Petra ; Koval, Dušan ; Severa, Lukáš ; Teplý, Filip ; Kašička, Václav
A fast and efficient capillary electrophoretic method was developed for enantioseparation of Ru(II) and Fe(II) polypyridyl complexes using anionic randomly sulfated alfa-, beta-, and gamma-cyclodextrins (S-alfa-CD, S-beta-CD, and S-gamma-CD) and their heptakis-(2,3-diacetyl-6-sulfato)-derivatives (Ac-S-alfa-CD, Ac-S-beta-CD, and Ac-S-gamma-CD) as chiral selectors. S-alfa-CD and S-gamma-CD were found to be the best chiral selectors providing high resolutions and short analysis times. The method was applied for the assessment of chiral purity of some batches of [Ru(bpy)3]2+ catalyst.
