Group- and electron-transfer reactions of tetracarbonylferrate(2-)

Article abstract of DOI:10.1021/om00054a047

Reactions of Fe(CO)₄^2- with metal carbonyl complexes lead to distinct mechanisms. Reaction with metal carbonyl cations gives a two-electron process that we interpret as a CO²⁺ transfer. Reaction with Mn₂(CO)₁₀ occurs by a single-electron transfer producing Fe₂(CO)₈^2- and Mn(CO)₅^-. Reaction with Mn(CO)₅Br also occurs by a single-electron transfer. Reaction with Re(CO)₅Br could be either SET or direct nucleophilic displacement. Kinetic studies are reported for several reactions.
