Reactions of 1,2,4,5-Tetrafluoro-3,6-bis(vinylsulfonyl)benzene with Nucleophilic Reagents Containing a Mercapto Group

Addition of 2-aminoethanethiol and 2-mercaptoethanol at both vinylsulfonyl groups of 1,2,4,5-tetrafluoro-3,6-bis(vinylsulfonyl)benzene occurs through the thiol group of the reagent and yields the corresponding 3,6-bis[2-(2-aminoethylthio)ethylsulfonyl] and 3,6-bis[2-(2-hydroxyethylthio)ethylsulfonyl] derivatives. The reaction of the title compound with 1,2-ethanedithiol leads to formation of only polymeric addition products.
