Oxidations Catalyzed by Ruthenium Porphyrins,zing agent and is also highly desirable when environmental requirements are considered. However, due to its biradical nature, dioxygen reacts with organic substrates preferably according to a radical chain mechanism, which generally operates with low selectivity. This radical reaction pathway may be

Oxygenation Reactions under Two-Phase Conditions, Such enzymes feature a Fe(III)-protoporphyrin IX at the active site where, after reduction, molecular oxygen is coordinated and activated through a very complicated mechanism, “reductive oxygen activation” (Scheme 1). High valent Fe-oxo species formation is favoured by the electron donation from a

Nitrene and Carbene Transfer Catalyzed by Metalloporphyrins,ids with the intermediate formation of oxoferryl complexes (1,2). It is now generally admitted that the active species which are formed as intermediates in the catalytic cycle of these hemeproteins and which are able to oxidize various substrates are iron-oxo complexes formally equivalent to Fe(V)=O

On the Electronic Structure of Oxo-Metalloporphyrins and Mechanistic Aspects of Oxygen-Transfer Rea1,2]. These compounds are interesting because of the similarity to the oxidation enzymes [1,2]. In order to learn more about the structure and catalytic properties of these systems in nature, metalloporphyrins have served as model substrates [1,2]. Another aspect of the chemistry of metalloporphyrin

Cytochromes are involved in the transfer of electrons from flavoproteins to dioxygen in the mitochondria of higher organisms and play important roles in the respiratory chain and in oxidative phosphorylation. These cytochro
