High-performance liquid chromatographic separation of metal carbonyl complexes substituted with bridging and chelating 1,1'-bis(diphenylphosphino)ferrocene

Abstract

The high-performance liquid chromatography of metal carbonyl complexes including those containing the 1,1'-bis(diphenylphosphino)ferrocene ligand is reported. Separations were performed on a column packed with silica bonded with polar amino-cyano groups. The results suggest that it is the polarity of the complexes that largely determines their retention characteristics under the conditions considered.
