    Abstract

    A newly established catalyst system for oxygen-oxidative polymerization of diphenyl disulfide is reported. Combination of vanadyl compounds (e.g., VO(acac)<inf>2</inf>) and triphenylmethylium tetrakis(pentafluorophenyl)borate (TrB(C<inf>6</inf>F<inf>5</inf>)<inf>4</inf>) proceeds the polymerization to give poly(1,4-phenylene sulfide) (PPS) at 100 °C. When triphenylmethylium tetrafluoroborate (TrBF<inf>4</inf>) 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<inf>2</inf>O from O<inf>2</inf> and protons that are eliminated from the monomer. Strong-acid-free oxygen-oxidative polymerization of PhSSPh is presented, catalyzed by a vanadyl and TrBR<inf>4</inf> system. TrB(C<inf>6</inf>F<inf>5</inf>)<inf>4</inf> is found to activate VO(acac)<inf>2</inf> at 100 °C and the catalyst gives poly(1,4-phenylene sulfide) (PPS) from PhSSPh. TrBF<inf>4</inf> has stronger nucleophilicity, but is found to activate VO(salen) and VO(TPP) at 160 °C for preparing PPS.
