Arene displacement from the title complex occurs under unprecedented mild conditions in neutral media to afford (η6-arene)tricarbonylchromiumcomplexes. 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

Several methods for the synthesis of tricarbonyl(η6-quinaldine)chromium 4 were investigated. Whereas thermal and photochemical complexation gave exclusively pentacarbonyl(η1-quinaldine)chromium 2, thermal and high pressure ligand exchange reactions employing (CH3CN)3Cr(CO)3 and tricarbonyl(η6-naphthaline)chromium 3 respectively gave only low conversions. However, the desired complex 4 was obtained
