Page/Page column 56-57, (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).

A study of the stereoselective synthesis of cis- and trans-Ph2TeX4 (X=F, Cl) supports a two pathway mechanism in which oxidative addition leads to the cis isomer while subsequent isomerization leads to the trans isomer.
