Vicariousnucleophilic substitutions (VNS) of hydrogen in 1-nitro-4-(pentafluorosulfanyl)benzene with carbanions provide 2-substituted 1-nitro-4-(pentafluorosulfanyl)benzenes in good to high yields. VNS of 1-nitro-3-(pentafluorosulfanyl)benzene gives a mixture of 6- and 4-substituted 1-nitro-3-(pentafluorosulfanyl)benzenes in 85:15 to >98:2 ratio and good to high yields. In basic media, the VNS reactions

available 4-nitro-(pentafluorosulfanyl)benzene through vicariousnucleophilic substitution of hydrogen (VNS) reaction, reduction of nitro group and cyclization of resulting anilines were described. Transformations of 5-SF5-indazoles led to a variety of SF5-substiuted heteroarenes that can serve as a versatile building block for diversity-oriented organic synthesis.
