A new easy access to quinones from iron porphyrin-catalysed oxidation of methoxyarenes by magnesium monoperoxyphthalate
Abstract
Electron-rich methoxyarenes were oxidized with high yields (55–100%) and under mild conditions to the corresponding paraquinones by magnesium monoperoxyphthalate in the presence of catalytic amounts of a water-soluble iron porphyrin; the reaction was used to prepare methoxatin.
