Fund Project: This work was supported by the National Natural Science Foundation of China (Grant No. 20072025).

The catalytic performance of a series of cobalt (Ⅱ) hydroxamates (CoL₂) and the synergistic catalytic action of the cobalt complexes combined with N-hydroxyphthalimide (NHPI) in the aerobic oxidation of p-xylene to p-toluic acid (PTA) were investigated. The results showed that the existing synergistic action in the catalytic oxidation can shorten the induction period of the radical reaction and improve the yield of PTA.
