Application of the Pfeiffer effect to partial resolution of tris(acetylacetonato)cobalt(III).
Partial resolution of neutral [Co(acac)3] was performed by extracting into 1,2-dichloroethane the complex formed when racemic Li[Co(acac)3] was mixed with Δ- or Λ-[Co(phen)3]Cl3 in water. This system is the first Pfeiffer-active system in which a dissymmetric metal complex serves as a chiral environment compound.
