Metal Complexes of Porphine and Azaporphine Compounds as Catalysts of Reactions Involving Oxidation by Molecular Oxygen

Autor: K A Bogdanova, N S Enikolopyan, K A Askarov

Publikováno v: Russian Chemical Reviews. 52:13-26

The results of studies of the catalytic action of the metal complexes of porphines and azaporphines in reactions involving oxidation by molecular oxygen are surveyed. Various mechanisms of the action of the metal-porphine catalysts are analysed and a

Tetrapyrrole complexes of cobalt as catalysts of the oxidation of epinephrine

Autor: L. Ya. Simonova, K. A. Askarov, G. G. Tsoi

Publikováno v: Chemistry of Natural Compounds. 19:334-338

A scheme is proposed for the qualitatively different catalytic effects of metalloporphyrins in reactions involving the oxidation of epinephrine. A metallocomplex of porphyrin may accelerate the oxidation of some substances and inhibit the oxidation o
