Manganese and iron tetraphenylporphyrin-catalyzed oxidation of a cardanol derivative (hydrogenated tert-butylcardanol)

Manganese and iron 2,6-disubstituted meso-tetraphenylporphyrins, bearing halogen atoms on the β-positions, have been used as catalysts for the oxidation of a cardanol derivative (hydrogenated tertbutylcardanol), using iodosilbenzene or hydrogen peroxide as oxygen atom donors. The reaction products can be correlated to the catalyst structure and to the nature of the oxidants. © 2002 Society of Porphyrins & Phthalocyanines
