Synthesis of 5-(4-hydroxyphenyl)-10,15,20-tris[3,5-di(tert-butyl)-4-hydroxyphenyl]porphine and 5-(4-palmitoyloxyphenyl)-10,15,20-tris[3,5-di(tert-butyl)-4-hydroxyphenyl]porphine and generation of phenoxyl radicals from them

A porphyrin with a lipophilic hydrocarbon substituent, 5-(4-palmitoyloxyphenyl)-10,15,20-tris[3,5-di(tert-butyl)-4-hydroxyphenyl]porphine, was synthesized for the first time by acylation of
(4-hydroxyphenyl)-10,15,20-tris[3,5-di(tert-butyl)-4-hydroxyphenyl]porphine. Oxidation of these compounds with PbO2 in toluene leads to the corresponding phenoxyl radicals.
