ChemInform Abstract: cine and tele Nucleophilic Substitutions in (η6-Arene)tricarbonylchromium and Tricarbonyl(η5-cyclohexadienyl)manganese Complexes

Addition of a nucleophile to an (η6-arene)tricarbonylchromium or a tricarbonyl(η5-cyclohexadienyl)manganese complex substituted with a leaving group X (X = F, Cl, OMe, OPh, NR2) affords (after treatment with acid) new complexes with the same η6 or η5 hapticity. The overall reaction involves addition of the nucleophile ortho, meta, or para with respect to the leaving group and HX elimination. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
