The activation of dioxygen is the major challenge in the catalytic oxygenation of hydrocarbons under mild conditions. In this study, the catalytic efficiency for the aerobic oxidation of toluene and its derivatives by using cobaltmeso-tetraphenylporphyrin was enhanced by using acetylacetone as the oxygen activator. The influences of reaction conditions such as solvent, different metalloporphyrin catalysts, temperature, pressure and acetylacetone loading were studied, as well as the kinetics of the oxidation. Various toluene derivatives could also be oxidized to the corresponding products in satisfactory yields with this catalytic system. Based on the characterization ofin situelectron paramagnetic resonance (EPR) andin situUV-vis spectroscopy, the catalytic mechanism was also proposed, in which acetylacetone served as the key initiator of the free radical in activating dioxygen.
