Synthesis and nucleophilic aromatic substitution of 3-fluoro-5-nitro-1-(pentafluorosulfanyl)benzene

3-Fluoro-5-nitro-1-(pentafluorosulfanyl) benzene was prepared by three different ways: as a byproduct of direct fluorination of 1,2-bis-(3-nitrophenyl) disulfane, by direct fluorination of 4-nitro-1-(pentafluorosul...
