A newly established catalyst system for oxygen‐oxidative polymerization of diphenyl disulfide is reported. Combination of vanadyl compounds (e.g., VO(acac) 2 ) and triphenylmethylium tetrakis(pentafluorophenyl)borate (TrB(C 6 F 5 ) 4 ) proceeds the polymerization to give poly(1,4‐phenylene sulfide) (PPS) at 100 °C. When triphenylmethylium tetrafluoroborate (TrBF 4 ) is applied with vanadyl tetraphenylporphyrin (VO(TPP)) or N,N′ ‐(ethylenebis(salicylideneaminato))oxovanadium (VO(salen)), PPS is also given via polymerization under conditions near 160 °C. Combination of the vanadyl complex and the borate affords the first protic‐acid‐free catalytic system for the polymerization of the disulfide, suggesting the overall reaction to produce PPS and H 2 O from O 2 and protons that are eliminated from the monomer.
