Reactions of Manganese Porphyrins with Peroxynitrite and Carbonate Radical Anion

We have studied the reaction kinetics of ten manganese porphyrins, differing in their meso substituents, with peroxynitrite (ONOO–) and carbonate radical anion (CO3·¯) using stopped-flow and pulse radiolysis, respectively. Rate constants for the reactions of Mn(III) porphyrins with ONOO– ranged from...
