Fluorinated tellurium(IV) azides and their precursors

The perfluoroaryl tellurolates C6F5TeLi (1) and 4-CF3C6F4TeLi (2) were prepared. These intermediates were identified by NMR spectroscopy and may form, depending on the reaction conditions, either the corresponding ditellanes C6F5TeTeC6F5 (3) and CF3C6F4TeTeC6F4CF 3 (4) by subsequent oxidation, or in the case of 1, a telluranthrene (C6F4Te)2 (5) by reaction with itself. The halogenation products of 5, (C6F4Te)2F4 (6), (C6F4Te)2Cl4 (7), (C6F4Te)2Br4 (8), as well as the azidation product (C6F4Te)2(N3)4 (9) were synthesized. Furthermore, in pursuit of our recent work on tellurium azides, the syntheses and properties of R2Te(N3)2 (R=CF3 (10), C6F2H3 (11)) and RTe(N3)3 (R=CF3 (12) and C6F5 (13)) are reported. The crystal structures of CF3C6F4TeTeC6F4CF 3 (4) (C6F4Te)2Br4 (8), and (C6F2H3)2Te (N3)2 (11) were determined.

PERFLUORORGANOTELLUR-VERBINDUNGEN: DIE SYNTHESEN VON C6F5TeTeC6F5, Hg(TeC6F5)2,CF3TeTeC6F5, CF3TeC6F5 UND PENTAFLUORPHENYLFURANEN

Bis(pentafluorophenyl)ditellurium Te2(C6F5)2 and the three new furan derivatives 2- and 3-pentafluorophenylfuran and 2,5-dihydro-2-pentafluorophenylfuran are prepared by irradiating a mixture of Te(C6F5)2 and furan.Te2(C6F5)2 reacts with elemental mercury to yield Hg(TeC6F5)2.From the reactions of Tex(CF3)2 with Tex(C6F5)2 (x = 1, 2) equilibria are formed with the unsymmetrical compounds CF3TexC6F5.The syntheses, NMR, and mass spectra of these new compounds are described.
