Functionalized chiral arene-tricarbonylchromium complexes are of great potential interest in asymmetric synthesis. Of these chiral complexes only the racemic acids 2 have been readily resolved previously.1 4 Resolution of the racemates of 

Separation of diastereomeric mixtures by chromatography, e.g., 4a from 4all and 

I Caution. Benzene, a reported carcinogen, is used in several steps in these syntheses. Appropriate precautions must be taken, and an efficient hood must be used.
