- Synthesis of Diaryliodonium Salts Having Pentafluorosulfanylarenes and Their Application to Electrophilic Pentafluorosulfanylarylation of C-, O-, N-, and S-Nucleophiles
-
Novel reagents for the electrophilic introduction of pentafluorosulfanyl (SF5) arenes into target molecules are disclosed. Unsymmetrical diaryliodonium salts 1 having SF5-arenes were synthesized by a one-pot process from iodo-SF5-benzenes 2 in good yields. The SF5-aryliodonium salts 1 were found to be efficient for the electrophilic SF5-arylation of carbon and heterocentered nucleophiles to furnish the corresponding substituted SF5-arenes in good to high yields.

- 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.
