Nitric oxide complexes of metalloporphyrins: an overview of some mechanistic studies

摘要

This review presents an overview of the mechanistic chemistry concerned with the reactions of metalloporhyrins involving the iboregulatory molecuel nitric oxide. Topics disucssed include the photolabilization of NO from metal nitrolyls complexes, the formation and dissociation of M-NO bonds, reductive nitrosylation of ferrheme proteins and oxida- tions of NO by dioxygen. Principal emphasis is given to prohyrin complexes of the first transition row metals and especially of iron(II) and iron (III).
