- PROCESS FOR THE PREPARATION OF 3- AND 4-(PENTAFLUOROSULFANYL)BENZENES
-
Process for the preparation of substituted 3- and 4-(pentafluorosulfanyI)benzenes of general formula 3 and 4 by nucleophilic aromatic substitution, where nitrobenzene having pentafiuorosulfanyl group connected in position 3 or 4 is allowed to react in concentration range 0.01 to 8.0 mol.l-1 with compound RY-M+, where R is selected from a group comprising saturated, unsaturated, acyclic, cyclic or aromatic, substituted or unsubstituted carbon chain, Y is the element of VI. B group and M+ is the metal ion, in an organic solvent. The invention includes also further chemical modifications of primary products.

-
Nucleophilic aromatic substitution of the nitro group of para- and meta-nitro-(pentafluorosulfanyl)benzene with alkoxides and thiolates generates a range of substituted 4- and 3-(pentafluorosulfanyl)benzenes in a single-step reaction.
