The transfer of a nitrosyl ligand between neutral and oxidized iron and cobalt metalloporphyrins in dichloromethane solutions was investigated by electrochemistry and FTIR or ESR spectroelectrochemistry. The transfer of NO from (P)Co(NO) to (P)Fe, from [(P)Co(NO)]+ to (P)FeClO4, and from [(P)Fe(NO)]+ to (P)Co was demonstrated for complexes where P = the dianion of tetraphenylporphyrin (TPP), meso-tetrakis(2,4,6-trimethylphenyl)porphyrin (TMP), or octaethylporphyrin (OEP). The driving force in these reactions is related to both the nature and oxidation state of the central metal in (P)M(NO) or [(P)M(NO)]+, where M = Fe or Co, and follows the order (P)Fe(NO) > (P)Co(NO) > [(P)Fe(NO)]+ > [(P)Co(NO)]+.
