Abstract

This paper summarizes the present state of the preparations and chemical properties of perfluoroalkyl, mainly trifluoromethyl tellurium compounds. Te(CF3)2 is a reactive educt for trifluoromethyl transfer reactions in inorganic and organic syntheses. CF3TeTeCF3 is used as a starting material for preparations of CF3Te compounds, e.g. Hg(TeCF3)2, CF3Tel. The pyrolysis of (CH3)3SnTeCF3 gives difluoro telluroketone. Te(CF3)2 is easily oxidized to yield trifluoromethyl tellurium(IV) derivatives. The preparations and properties of many compounds of the composition (CF3)2TeX2 are described. Nucleophilic trifluoromethylation of (CF3)2TeCl2 yields tetrakis(trifluoromethyl) tellurium(IV).
