N2  - Chelation of dimethylmalonate derivatives of variously substituted tricarbonyl(cyclohexadienyl)-iron(1+) salts by tris(3-trifluoroacetyl-(+)-camphorato)europium(III) successfully resolved the methoxy resonances due to the two epimers of the cyclohexadiene complexes in the 1H n.m.r. spectra of racemic samples. The method provides a general means to measure enantiomeric excess of tricarbonyliron complexes.
