Acetylacetone as an oxygen activator to improve efficiency for aerobic oxidation of toluene and its derivatives by using cobalt meso-tetraphenylporphyrin

An efficient system comprising acetylacetone and cobalt tetraphenylporphyrin was developed for the aerobic oxidation of toluene and its derivatives, in which acetylacetone served as the key initiator of the free radical in activating dioxygen.
