Formation of substituted cyclohexadienyl tricarbonylmanganese complexes by nucleophilic addition reactions of functionally substituted (η-arene)tricarbonylmanganese cations

Abstract

Cyclohexadienyl and 6-exo-methyl- or -phenyl-cyclohexadienyl complexes bearing halogeno-, alkoxy-, or dialkyl-amino-substituents in the 1- or 2-positions are obtained by reaction of lithium tetrahydridoaluminate or methyl-or phenyl-lithium with the appropriately substituted (η-arene)tricarbonylmanganese salt. Directive effects in these nucleophilic additions are compared with those observed for arene complexes of iron and chromium.
