Abstract

Evidence is presented on the basis of literature data that the disproportionation of H O , catalyzed by the Co(III) complex of hematoporphyrin IX (Co HP), proceeds via the following mechanism:Co HP(H O ⇌Co HP(OOH )+H Co HP(OOH )+H O ⇌Co HP(OOH )(H O )Co HP(OOH )(H O )→ Co HP+H O +OH + O . The corresponding equilibrium and rate constants are estimated. © 1975. 2 2 2 2 2 2 2 2 2 2 2 2 2 III III III - + III - III - III - III -
