Chiral Separation of Racemic Tetrahedral Transition Metal Carbonyl Cluster SFeCoMo(CO)8(C2H5OCOCp) by Liquid Chromatography on Tribenzoylcellulose

Abstract Direct separation of racemic tetrahedral transition metal carbonyl cluster SFeCoMo(CO)8(C2H5OCOCp) has been conducted by liquid chromatography using tribenzoylcellulose as chiral stationary phase. The effects of concentration of 2-propanol, various primary alcohols in the mobile phase and column temperature on the rentention and enantioselectivity of SFeCoMo(CO)8(C2H5OCOCp) cluster enantiomers were studied. The maximum resolution factor obtained was 2.306 when hexane/2-propanol(99.5/0.5,v/v) was used as solvent at 23°C.
