Reversible oxidations in ditertiary-phosphine bridged derivatives of [(π-C5H5)Fe(CO)2]2

Abstract

The carbonyl–diphosphine bridged dimer [(π-C5H5)Fe(CO)]2[Ph2P(CH2)3PPh2]{Fe2(diphos)} is reversibly oxidized electrochemically to the cation Fe2(diphos)+ which disproportionates in acetonitrile and is further oxidized to the transient dication Fe2(diphos)2+.
