Direct synthesis of (η 6-arene)-tricarbonylchromium complexes by arene displacement from tricarbonyl(η 5-1-methylpyrrole)chromium(0)

Abstract

Arene displacement from the title complex occurs under unprecedented mild conditions in neutral media to afford (η 6-arene)tricarbonylchromium complexes. The process is most effective with heteroaromatic compounds: the first synthesis of a tricarbonyl(η 6-quinoline)chromium complex and the diastereoselective preparation of a (η 6-indole) complex derived from L-tryptophan are reported as representative examples.
