Synthesis, structures and properties of CF3S-substituted tellurium compounds.
New prepns. for the following compds. are described: Te(SCF)2, Te(NSO)2, and Cl2Te(NSO)2. The catalytic or thermal SO2 elimination from Cl2Te(NSO)2 affords a coordinated or noncoordinated thiachalcogenadiazole. Conversions of these compds. are reported. Evidence for the proposed mechanism for the reaction between Te(NSO)2 and SbCl5 is provided. Cl4Te2N2(SCF3)2, prepd. from TeCl4 and CF3SN(SiMe3)2, reacts with LiN(SiMe3)2 to form [(Me3Si)2N]4Te2N2(SCF3)2. An x-ray structural anal. of Cl4Te2N2(SCF3)2 is presented.
