✦ Synopsis

Treatment of X-substituted (g6-arene)tricarbonylchromium complexes with a nucleophile and a proton source afforded new arenetricarbonylchromium complexes via chromium hydride intermediates and elimination of HX (cine and tele nucleophilic aromatic substitutions). Treatment of (g5-X-substituted-cyclohexadienyl )tricarbonyl manganese complexes with hydride and a proton source gave g5-cyclohexadienyl complexes resulting from a cleavage of the C-X bond: the g3-X-substituted cyclohexenyl intermediates underwent elimination of an agostic hydrogen and the X group.

Addition of a nucleophile to an (η 6 -arene)tricarbonylchromium or a tricarbonyl(η 5 -cyclohexadienyl)manganese complex substituted with a leaving group X (X = F, Cl, OMe, OPh, NR 2 ) affords (after treatment with acid) new complexes with the same η 6 or η 5 hapticity. The overall reaction involves
