The polymerization via selective oxidation utilizing oxygen as the oxidant presents potentially a desirable low-cost method for upgrading the value of raw materials. The most successful example is the oxidative polymerization of 2, 6-dimethylphenol to yield poly (2, 6-dimethyl-1,4-phenylene oxide) using a copper-amine catalyst in an oxygen atmosphere at room temperature(Eq. 1).1 Our studies on the preparation of poly (p-phenylene sulfide) (PPS), which deserves much attention as a high-performance engineering plastic owing to its excellent chemical, thermal, and mechanical properties,2 have revealed that thiophenol and diphenyl disulfide are oxidatively polymerized to PPS via a cationic mechanism by electrochemical or chemical oxidations (Eq. 2).3-6 The oxovanadium catalyst acts as an efficient catalyst for the O2 polymerization of diphenyl disulfide.7
