A method was developed to prepare poly(thio-1,4-phenylene) (PPS) from prepolymers containing alkylsulfoniophenylene units by dealkylation of sulfonium moities using nucleophilic reagents. Selenoanisole was quantitatively obtained by the condensation of selenophenol with methyl iodide in H2O in the presence of NaOH. Aryl selenides were produced by Swern condensation of alkyl selenoxides followed by the nucleophilic dealkylation of the resulting selenonium salts.
