A. Goti et Mf. Semmelhack, DIRECT SYNTHESIS OF (ETA-6-ARENE)-TRICARBONYLCHROMIUM COMPLEXES BY ARENE DISPLACEMENT FROM TRICARBONYL(ETA-5-1-METHYLPYRROLE)CHROMIUM(0), Journal of organometallic chemistry, 470(1-2), 1994, pp. 30000004-30000007
Arene displacement from the title complex OCCURS under unprecedented M
ild conditions in neutral media to afford (eta6-arene)tricarbonylchrom
ium complexes. The process is most effective with heteroaromatic compo
unds: the first synthesis of a tricarbonyl(eta6-quinoline) chromium co
mplex and the diastereoselective preparation of a (eta6-indole) comple
x derived from L-tryptophan are reported as representative examples.
