Abstract

Tetra(meso-aryl)porphyrins containing 2,6-dimethoxyphenol unit distant from the macrocycle and adjacent to it have been prepared. Radical scavenging activity of the obtained compounds has been estimated in the model reaction of ethylbenzene oxidation initiated by azobisisobutyronitrile. It has been shown that the phenol hydroxy group ability to inhibit ethylbenzene oxidation depends on the environment of phenol group.

Keywords

tetra(meso-aryl)porphyrins, substituted phenols, radical scavenging activity, stoichiometric inhibition coefficients, inhibited oxidation of ethylbenzene
