摘要：

Laser flash-photolytic studies along with determination of the hydroxylation kinetics of salicylic acid under continuous irradiation (lambda(irr) = 589 nm) have shown that the active species inducing the photoreduction of Fe(III) salicylate (i.e. the photogeneration of the catalyst) is the excited singlet state of methylene blue, (1)MB(+). The hydroxylation products are 2,3- and 2,5-dihydroxybenzoic acid. Binuclear complexes containing iron in various oxidation states (i.e. Fe(II) and Fe(III)) seem to be effective hydroxylation catalysts.
