✦ Synopsis

Reaction of 1-naphthol and related phenols with hydrogen peroxide catalysed by 5,10,15,20-tetra pentafluorophenyl por-Ž . phyrinatoiron III chloride gives corresponding quinones and oxidative phenol coupled products, whereas the reaction of Ž . naphthols with hydrogen peroxide catalysed by 5,10,15,20-tetramesitylporphyrinatoiron III chloride give above products along with quinone epoxides in moderate yields. The reaction of quinone with potassium superoxide catalysed by Ž . Ž . Me TPPFe III Cl and p-MeOTPPFe III Cl give higher yields of quinone epoxides than the reaction of quinone with 12 Ž . hydrogen peroxide catalysed by 5,10,15,20-tetraarylporphyrinatoiron III chlorides.
