Page/Page column 46-47, (2019/12/25)
The present invention relates to a process for preparing a polyfluorinated compound of formula Ar-Ri(l), wherein Ar-Ri(l) is an aromatic ring system wherein R1 is selected from the group consisting of SF4CI, SF3, SF2CF3, TeFS, TeF4CF3, SeF3, IF2, SeF2CF3, and IF4, X2 is N or CR2, X3 is N or CR 3, X 4 is N or CR 4, X 5 is N or CR 5, X 6 is N or CR 6, and the total number of nitrogen atoms in the aromatic ring system is between 0 and 3, and if X 5 is CR 5 and X 6 is CR 6 R 5 and R 6 may form together a saturated or unsaturated five or six membered ring system comprising one or more nitrogen, wherein said five or six membered ring system may be substituted with one or more residues R 7 said process involving the following reaction step reacting a starting material selected from the group consisting of Ar2S2, Ar2Te2, Ar2Se2, ArSCF3, Arl, ArTeCF3, ArSeCF3, ArSCF3, and ArSCI, wherein Ar has the same definition as above, with trichloroisocyanuric acid (TCICA) of the formula (III) in the presence of the alkali metal fluoride (MF).

, p. 279 - 283 (2007/10/03)
The synthesis and mechanism of formation of cis- and trans-Ph2SF4 is described. Starting compounds are Ph2S or Ph2SF2 and the oxidizing agent is XeF2 in the presence of Et4NCl. Also described is the synthesis of related chalcogen(IV and VI) fluorides such as t-butylSF3, difluorodibenzothiophene, PhSeF3, Ph2SeF2, PhSF5, p-MeC6H4SF5, PhSeF5, and PhTeF5. The reactions of Ph2S(O)F2 with alcohols and with the H2O-HF-glass system are briefly described.
