Additions of Carbanions to a Cationic Cyclopentadienyl(naphthalene)iron Complex

A simple change in the substitution pattern of the naphthalene ligand can effectively alter the reaction pathway: the reaction of [Cp(naphthalene)Fe]PF6 with carbon nucleophiles results in reduction of the Fe center, but complex 1 reacts with PhLi by nucleophilic addition at the condensed arene. Whe...

Zusammenfassung:A simple change in the substitution pattern of the naphthalene ligand can effectively alter the reaction pathway: the reaction of [Cp(naphthalene)Fe]PF6 with carbon nucleophiles results in reduction of the Fe center, but complex 1 reacts with PhLi by nucleophilic addition at the condensed arene. When tBuLi is used as the nucleophile, addition to the Cp ring of 1 giving 2 is observed instead.
