  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).

  本发明涉及一种制备化学式为Ar-Ri(l)的多氟化合物的过程，其中Ar-Ri(l)是一个芳香环系统，其中R1选自SF4CI、SF3、SF2CF3、TeFS、TeF4CF3、SeF3、IF2、SeF2CF3和IF4的群组，X2为N或CR2，X3为N或CR3，X4为N或CR4，X5为N或CR5，X6为N或CR6，芳香环系统中氮原子的总数在0到3之间，如果X5为CR5且X6为CR6，则R5和R6可以共同形成一个饱和或不饱和的含有一个或多个氮原子的五元或六元环系统，其中所述的五元或六元环系统可以被一个或多个残基R7取代，该过程涉及以下反应步骤：在碱性金属氟化物（MF）的存在下，将选自Ar2S2、Ar2Te2、Ar2Se2、ArSCF3、Arl、ArTeCF3、ArSeCF3、ArSCF3和ArSCI的起始物质与化学式为(III)的三氯异氰尿酸（TCICA）反应。

  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.

  对顺-和反-Ph 2 TeX 4（X = F，Cl）的立体选择性合成的研究支持两个途径的机制，其中氧化加成导致顺式异构体，而随后的异构化导致反式异构体。

  The reaction of azide with organotellurium(VI) halides Ph5TeBr and cis-(biphen)(2)TeF2 (biphen = 2,2'-biphenyldiyl) resulted in the formation and isolation of Ph5TeN3 (1) and cis-(biphen)(2)Te(N-3)(2) (2), which are the first tellurium(VI)-azide species. In addition to spectroscopic data, both crystal structures have been determined. Furthermore, the stability of possible Te(VI) species with higher azide contents PhxTe(N-3)(6-x) and MexTe(N-3)(6-x) as well as the syntheses and properties of their Ph/MexTeFy precursors was investigated, including the crystal structure determination of trans-Ph2TeF4 (3). Ab initio and density functional studies of all molecules regarding the structures and electronic populations were performed.
