Reactions of water soluble iron(II) and cobalt(II) porphyrins with nitric oxide. Implications for the reactivity of NO and biologically relevant metal centers

Abstract

The entropies and volumes of activation (ΔSon and ΔVon) for the fast reactions (kon > 109 dm3 mol–1 s–1) reaction of NO with the water soluble iron(II) porphyrin complexes FeII(TPPS) [TPPS = tetrakis(4-sulfonatophenyl)porphinato] and FeII(TMPS) [TMPS = tetrakis(sulfonatomesityl)porphinato] are small and positive indicating that these reactions are dominated by the diffusion processes as is the analogous formation of the cobalt(II) complex CoII(TPPS)(NO).
