Arene displacement from the title complex occurs under unprecedented mild conditions in neutral media to afford (η⁶-arene)tricarbonylchromium complexes.The process is most effective with heteroaromatic compounds: the first synthesis of a tricarbonyl(η⁶-quinoline)chromium complex and the diastereoselective preparation of a (η⁶-indole) complex derived from L-tryptophan are reported as representative examples.Key words: Chromium; Arene; Pyrrole; Quinoline; Indole; Diastereoselectivity
