Abstract

η6-Arene-η5-cyclopentadienyliron salts containing electron withdrawing groups such as nitro, halogeno, benzoyl, cyano, and sulphonyl on the arene ring react with carbanions to give eletroneutral adducts of the Yanovsky type; these adducts give the corresponding substituted benzene on treatment with buffered cerium (IV) ammonium nitrate.
