New 4-Pentafluorosulfanyl and 4-Perfluoroalkylthio Derivatives of 1-Chloro-2-nitro- and 1-Chloro-2,6-dinitrobenzenes. — Compounds (II) are obtained by fluorination of disulfides (I) with AgF2, while perfluoroalkylation is carried out by means of
thermolytic reactions with Xe(II) bis(perfluoroalkylcarboxylates). The introduction of
fluorine-containing substituents into the aromatic ring reinforces the activation of the
halogen substituents towards nucleophilic attack. Several nucleophilic substitution reactions are carried out and by this way N- and S-containing groups are introduced into
the benzene ring. — (SIPYAGIN, A. M.; ENSHOV, V. S.; KASHTANOV, S. A.;
